Understanding Venules: The Small Veins That Keep Your Body Alive

Venules are small veins that carry blood away from the capillaries and back towards the heart. They are the smallest veins in the body, and they play an important role in the circulatory system by collecting blood from the tissues and organs and transporting it back to the heart for oxygenation and distribution to other parts of the body.

Venules are typically found in the skin, muscles, and other tissues throughout the body. They are very thin-walled and have a diameter of only a few micrometers. They receive blood from the capillaries and then merge into larger veins, which eventually return blood to the heart.

In summary, venules are small veins that collect blood from the tissues and organs and transport it back to the heart for oxygenation and distribution to other parts of the body.
