What Is Blood Pressure hypotension hypertension systolic diastolic pressure
Hi i m sami from fawzi academy In this tutorial I will generally talk about blood pressure Blood pressure BP is the pressure exerted by circulating blood upon the walls of blood vessels and is one of the principal vital signs. blood pressure usually refers to the arterial pressure of the systemic circulation, usually measured at a person's upper arm. A person's blood pressure is usually expressed in terms of the systolic pressure over diastolic pressure and is measured in millimeters of mercury mm Hg. Normal resting blood pressure for an adult is approximately 12080 mm Hg.
Blood pressure varies depending on situation, activity, and disease states, and is regulated by the nervous and endocrine systems. Blood pressure that is pathologically low is called hypotension, and pressure that is pathologically high is hypertension. Both have many causes and can range from mild to severe, with both acute and chronic forms. Chronic hypertension is a risk factor for many complications, including peripheral vascular disease, heart attack, and stroke. Hypertension is generally more common, also due to the demands of modern lifestyles. Hypertension and hypotension go often undetected because of infrequent monitoring.
THE CARDIAC CYCLE HEARTBEAT DIASTOLE SYSTOLE Blood Pressure
Hi I m Sami from fawzi academy In this tutorial I will explain the relation between the blood pressure and cardiac cycle The cardiac cycle is the complete heartbeat from its generation to the beginning of the next beat, and so includes the diastole, the systole, and the intervening pause. The frequency of the cardiac cycle is described by the heart rate, which is typically expressed as beats per minute. Under normal circumstances, each cycle takes 0.8 seconds.2 Each beat of the heart involves five major stages. The first two stages, often considered together as the ventricular filling stage, involve the movement of blood from the atria into the ventricles. The.
Next three stages involve the movement of blood from the ventricles to the pulmonary artery in the case of the right ventricle and movement of blood to the aorta in the case of the left ventricle. Throughout the cardiac cycle, blood pressure increases when the atrium contracts and decreases at ventricular filling stage Systole is the part of the cardiac cycle understood as a force that drives blood out of the heart. it usually means the contraction of the left ventricle When the smaller, upper atria chambers contract in late diastole, they send blood down to the larger, lower ventricle chambers. When the lower chambers are filled.
And the valves to the atria are closed, the ventricles undergo is volumetric contraction marking the first stage of systole. The second phase of systole sends blood from the left ventricle to the aorta and body extremities, and from the right ventricle to the lungs. Thus, the atria and ventricles contract in alternating sequence. The left and right atria feed blood, at the same time, into the ventricles. Then, the left and right ventricles contract simultaneously as well. Diastole is the part of the cardiac cycle when the heart refills with blood following systole contraction. Ventricular diastole is the period during which the ventricles are filling and.
Minor changes in cardiovascular health reduce chances of stroke
The REGARDS Study, as I mentioned, is really large. So it enrolled about over 30,000 people and so it's a very rich database. The concentration is on stroke, but they've been able to tease apart lots of other risk factors for health conditions. Now in this study, the group at Alabama and Emory who work in the REGARDS Study were able to identify how the risk for stroke varied with what we call primary health factors. These health factors are things that we all know about and we'll talk about them in.
A second but they have been kind of packaged as The Simple 7s. And The Simple 7s is a way for people to just start thinking about their health. And so the seven factors in The Simple 7 are blood pressure control, glucose control, blood sugar control, cholesterol control, weight control, physical activity, diet, and smoking. So those are the seven things Seven Simple 7s. In this study, what they did was they looked at the risk of stroke in people and how that varied and how they were doing with regard to these Simple 7s.
Penn employee transforms health due to Be in the Know
The 'Be in the Know' program is a health incentive program offered by the university's HR department for faculty and staff that invited people to have their metabolic numbers screened and provided financial incentives to do so. It took less than a half hour and they tested your cholesterol, blood pressure and blood sugar levels. When I originally walked into the 'Be in the Know' program, I thought I was in pretty good control of my overall health. As it turned out, my screening told me a different story. When I spoke to the nurse and she told me.
How bad the blood pressure result was, I was definitely surprised. Then when she told me that I should leave and go straight to the ER, it was really an eyeopener. I'm married with four kids and thinking about them and knowing that my health was out of control like that, it made me realize that the time to change things was now. Since my initial 'Be in the Know' screening about 20 months ago, I've lost about 40 pounds and I'm much more active. I now eat much more fruits and vegetables.
The health changes that I've implemented particularly surrounding my diet have not been of my own doing. It's been a combination of my choices here and the way that my wife shops. She now stocks a lot more fruits and vegetables, focus on fresh, unprocessed foods and we routinely grill once a week so that we have leftovers and things of that nature to avoid the temptation of fast food when time gets away from us. After signing up with a gym, I enrolled in the Keystone Health Plan Incentive program.
That would reimburse me a portion of my fees after a hundred and twenty visits in a given year. I have started running which is something that I have never done in my life. I recently ran my first 5K with my 11yearold son. It's been a number of years since I was biking regularly. Biking used to be a routine part of my commute. Earlier this spring, when I found out about the Abramson Cancer Center's Ride to Conquer Cancer, that made me want to sign up because it had direct benefit where I work.
Is Soy a Good Source of Protein HealthiNation
Soy has been getting soy much attention lately, and there's a lot of conflicting information out there. Let's start with What is soy Soy is in the legumebean family that's native to southeastern Asia. Although it's been part of the Asian diet for thousands of years, soybeans were only introduced to America about two hundred years ago. Now, the U.S. states produce about half of the world's supply of soybeans. Soybeans contain 35 to 40 protein. These soybean proteins are complete which means they contain significant amounts of all the essential amino acids our bodies need but.
Can't make on our own. That's why soy protein can be a great substitute for animalbased protein that have complete proteins too but also contain more fat, especially unhealthy, saturated fat along with cholesterol. For such a tiny package, soy is a dietary powerhouse when it comes to biological action. That's because soybeans are uniquely rich in certain bioactive molecules called isoflavones. Isoflavones can function as an anti inflammatory, an antioxidant counteracting the damaging effects of free radicals in our cells, and they can even kill parasites! There are different forms of isoflavones. Some forms are more bioavailable, which means.
Our bodies can use them more easily than others. Most traditional Asian soy foods generally contain more of the bioavailable kind than do Western foods Isoflavones are found in a number of plants besides soy, like fava beans, and even in coffee! You can find a lot of products made with soy, but watch out for processed soy foods. Though usually high in protein, they typically contain lower levels of isoflavones. In addition to any possible biological action from isoflavones, many soy products are believed to be healthy. That's because of their high content of polyunsaturated fats the good.
Kind, fiber, vitamins and minerals, and their low content of saturated fat the bad kind. Eating soy foods might lower the risk of heart disease, type 2 diabetes and certain cancers like breast and prostate cancers, as well as improve bone health and give relief from menopausal symptoms. Now I've got your attention, right Well, you and millions of other people, But if you dig through all the medical literature, you'll find that it's complicated and it hasn't all been sorted out yet. Bottom line If you're using soy protein to.
Replace arteryclogging animal protein in your diet, then you're switching out saturated fat and bad cholesterol for a wiser protein source. That's a good idea. But if you're hoping to stave off heart disease with small amounts of processed soy or soy supplements, the benefits are much less certain. And if you're looking to soy protein or isoflavones to improve menopausal symptoms, postmenopausal bone loss, prevent or treat breast and prostate cancers, a lot more research needs to be done before a strong recommendation can be made. As part of a balanced diet, it's soy good.
Heart Valve Replacement Mechanical versus Tissue
To replace a heart valve we have mechanical valves and tissue valves. The mechanical valves are made of metallic alloy. Those valves tend to last forever, for the life of the patient. However, patients required to be on anticoagulants, and the anticoagulants that is required is called Coumadin, and it makes the blood thinner and therefore the patients are at an increased risk of bleeding. But they also need to regulate the levels of this anticoagulant and that involves doing a blood test. Those blood tests are required to be done once the levels are.
Stable, once a month. In addition to that, this mechanical valve makes noise and there's some dietary restrictions associated with the use of Coumadin that the patients need to comply with. On the other hand, we have tissue valves. The tissue valves are made either of cow tissue or pig tissue. Some of these valves are the actual valve of a pig. The cow tissue the cow valves are made with the sac around the heart from a cow. Both are are very good. They don't require to be on blood thinners except aspirin unless there's.
Other indications for the use of blood thinners. However, they don't last forever. The average duration ranges from ten to fifteen years. And after that patients the valve will need to be replaced. People are interested in a simpler lifestyle and compared to the mechanical valves they require less maintenance. They are people don't need to be patients don't need to be on on blood thinners in general when you have a tissue valve. And there's a a misconception in terms of the use of blood thinners and that's a that's a fear of bleeding,.
What Does Our Blood Really Composed of
The blood as we all know, have many different functions in the body. Most of them includes transportation of different nutrients including Oxygen, glucose, and enzymes. It also functions for protection, temperature and pH balance. But have you ever wonder what really composes our blood Generally, we can divide the blood into two main groups. The first one is called the Plasma. It fills the 55 of the total blood volume. It is the liquid component of the blood and it has no cellular content. The other 45 is the blood's cellular component.
And and it is divided into three different kinds of cells. The greatest portion goes to the Red Blood Cells at 80, and the ramaining 20 is shared by the white blood cell and the platelets. The Red blood cells contains a protein called the HEMOGLOBIN which is responsible for its characteristic red color and the ability to carry oxygen atoms. It fills the bulk of 7585 RBC count. The White blood cells however, is much fewer compared to Red blood cells and only comprises at about 6 of the cellular component.
These cells are further divided to five different cells namely Neutrophils, being the most abundant of all which covers about 60 Lymphocytes being the second most numerous, the monocytes, eosinophils and lastly the basophils. And the last but not the least, the platelets which is the main responsible for the blood clotting process. The plasma moreover, also composed of different compounds. This are the Water, being the largest at about 90, the proteins which consist of the albumin, the clotting factors and immunoglobulins at around 8, the Hormones which includes amines and steroids,.
Human Lungs Parts of Respiratory system Human anatomy 3D animation tutorials
Humans for respiration need a continuous supply of oxygen. Humans take in oxygen and leave out carbon dioxide, which is the poisonous waste product in the process of respiration. The lungs are essential respiratory organs in the human body. The human anatomy consists of two lungs. They can be called as the left and the right lung, respectively. The left lung has two lobes while the right lung has three lobes. The lungs contain approximately 1500 miles of airways and about 300 to 500 million alveoli. The total surface area is an approximate of 70m2 msquare in a fully grown human body,.
Roughly the size of a badminton court. An alveoli , also known as little cavity , is derived from the Latin word alveolus , and these are the terminal ends of a respiratory tree and are shaped like a hollowcavity. The average respiratory rates of a resting adult is about 1020 breaths per minute. We spend about 13rd of a minute in inhaling. The total breathing capacity, however depends on the individual, that is, it varies on factors depending on age, height, weight and sex. It is observed that females tend to have a.
2025 lower breathing capacity than males, while tall people tend to have a larger lung capacity than shorter people. And people living in lowlined areas, that is, at the sealevel, tend to have a smaller lung capacity than those people living at a higher altitude. People who smoke have a lower lung capacity than nonsmokers. Lungs function similar to that of bellows, which is a mechanical device that blows strong current of air. Lungs convert the hormones that cause the narrowing of blood vessels and drives the blood pressure up and also remove the waste.
Products in the blood. A lung is measured to be between 1012 inches long. The two lungs are separated by a structure called media sternum. The lungs are covered by a structure known as the pulmonary pleura. The lung is an important organ that performs various functions that happen every second of our lives, out of which breathing is considered to be the most essential. As previously mentioned, the lungs take in oxygen and give out carbon dioxide. The air that we breathe in, enters the human body and reaches to the lungs through a windpipe.
, called trachea, which branches further into two main tubes which distributes the air supply to both the left and the right lung , respectively. These tubes further divide themselves into 22 times the number of branches resulting in the formation of more than 100,000 smaller tubes, called bronchioles, and about 300 million air sacs or alveoli, which are only about a 0.3 mm in diameter. Since the walls of the alveoli are 150th the thickness of a tissue paper and are also covered up with millions of tiny blood vessels,.
Called capillaries, there is a freeflow exchange of both, oxygen and carbon dioxide, between the body and the environment. The lungs play an important role in the body's defense against infection and other harmful environmental factors. Air that is inhaled either through the nose or the mouth may consist of various dust particles or infectious agents, and ended up getting stored in the lungs. Mucus, which is a sticky liquid that is produced by the lungs, may trap the inhaled particles while the lung's white blood cells , that serve as protective agents, aid in the engulfment.
