Circulation of blood in vein

- Slow blood flow under low blood pressure - No pulse

Structure of capillary (1)

Thinnest wall which is one cell thick without any muscle or elastic tissue

Structure of capillary (2)

No valves

Structure of capillary (3)

Has smallest lumen

Function of capillary

Allows the exchange of gases, food and waste products between the blood and body cells via diffusion through the thin wall of the capillary

Circulation of blood in capillary (1)

Slow blood flow under decreasing blood pressure

Circulation of blood in capillary (2)

No pulse
