So this is about vassau construction.
00:03
Vassal construction.
00:05
Construction, okay? a very important aspect when you're dealing with the circulatory system.
00:13
And we have another term known as vassal dilation.
00:17
These two processes are important when it comes to heat regulation.
00:22
How do you regulate heat of the body? so you see, vosal constriction is kind of dependent on the core than on skin temperature, probably okay.
00:39
And caternese, vesal constriction is predominantly controlled through the sympathetic, a part of the autonomous, autonomic nervous system.
00:57
So therefore, we are going to, i'm trying to say here that versus construction is the narrowing of red vessels.
01:06
So if you see vessel, and then you have constriction.
01:11
To constrict something is to render it narrow.
01:19
So it's narrowing of blood vessels resulting from, you know, when the muscular walls of the vessels contract, okay? say scenario a, you have the normal sized blood vessel during the normal temperature, for instance, okay.
01:33
Then scenario b here, you have cold temperature, okay? say below 20 or below 15 degrees celsius...
