Now here we are addressing how barrow receptors work.
00:07
Okay, barrow receptors are pressure receptors.
00:16
Okay, in our arteries.
00:18
Now, barrow receptors are going to be triggered to send action potentials when stretched.
00:42
Well, not when the barrow receptors themselves are stretched, but when the arteries are stretched.
00:58
And when we're talking about stretch, we're not talking about stretch lengthwise.
01:02
If you're talking about the diameter, thinking about our circulatory system as a series of tubing, okay, stretched so that the diameter of the tube is larger.
01:14
Okay, so that means when you have a high blood volume, so lots of blood, they're going to be stretched more.
01:36
So here it's talking about decreased blood volume.
01:46
So with decreased blood volume, they're going to be stretched less.
02:05
So if they're stretched less, i forgot the h there, if they're stretched less.
02:11
Now remember, they're triggered to send action potentials when they are stretched.
02:19
So if they're stretched less, there's going to be less.
02:23
Less action potentials.
02:33
Okay, so if it makes sense, if you have a high blood volume, that means with a high blood volume, think about it, increased blood volume means more blood per stroke...
