What is a "venule"?

A venule is a small blood vessel that collects blood from capillaries and merges to form larger veins. They play a crucial role in the circulation of deoxygenated blood back to the heart, serving as a conduit for the return of blood from tissues and organs. Venules also participate in the exchange of nutrients, waste products, and immune cells between the bloodstream and surrounding tissues.

Examples

1. Small-vessel vasculitis affects small vessels like arterioles, capillaries, and venules.

2. Maybe as it ends the brachial artery and enters the arterial, maybe the beginning and the end of the capillaries also from the venule to a vein and also, wrapping it up, what the pressure is at the end.

3. The cells send their CO2 and other junk out to the venal end of the capillary exchange where the capillaries unite into venules, and then merge into veins that head back to the heart.

4. Blood then collects into small veins, called venules, then to larger veins and back to the heart.
