Hello students, the basic structure of a capillary bed consists of a meta arteriole.
00:07
A meta arteriole is this structure.
00:09
It is a small arteriole that delivers blood to the capillary bed.
00:14
The next major structure is the pre -capillary sphincters.
00:19
These structures are circular smooth muscle fibers that constrict and dilate to control the blood flow into the capillaries.
00:28
In the given diagram, these pre -capillary sphincters are open.
00:35
The next structure is the capillaries.
00:38
Capillaries, they are thin walled vessels that allows the gaseous exchange of substances and as well as exchange of nutrients and waste products between the blood and the tissues.
00:55
The next structure is the venules.
00:59
Venules, venules are small vessels that collect blood from the capillary bed and they converge to form veins.

These is the structure of the capillary bed...
