ADH effects on blood pressure Renal system physiology NCLEXRN Khan Academy
We left off the story of antidiuretic hormone when it was just secreted into the blood vessels of the posterior pituitary. So it was just synthesized, just made. It’s a little hormone. And ADH was on its way to different parts of the body. So let’s just pick up the story right there.
And figure out where does it go next. So this little molecule is, we said, a small peptide hormone made up of amino acids. And so I’m just going to draw it here. And this little hormone is going to go off to do a couple of important things. So we know at the end of the day, it really wants to increase blood pressure.
So one of the places it visits is all of the vessels of the body, all the arterial vessels of the body. And specifically, it targets smooth muscle. So this hormone is going to go and get this smooth muscle to constrict. And we know that when smooth muscles constrict, the blood vessels are actually going to tighten down,.
And we call that vasoconstriction. So the blood vessels are going to get tight and small, and that’s going to increase resistance. And increased resistance is going to relate to blood pressure. And we’ll talk about how we know that. There’s that formula. I’m going to write it over here delta P equals flow.
Q is flow times resistance, is R. And you can actually change that around to say arterial pressure minus venous pressure equals and we know the flow is actually stroke volume times heart rate, and it’s all multiplied by resistance. So if you look at this, and if we assume for the moment that the venous pressure is going.
To be basically unchanged, then anything that increases the resistance over here is going to increase our pressure over here. So that’s why, in this case, if ADH is able to cause constriction of the blood vessels and increase resistance, our pressure would go up as well. So that’s actually one of the things that it does. And the other thing that it does is.
It’s going to act on the kidney. So it’s going to have an effect on the kidney. Here’s my kidney. And specifically what it’s going to do is it’s going to cause increased reabsorption of water. So increased reabsorption of water is going to increase our stroke volume. So now you can see the other key effect it’s going to have.
