- Circulates OXYGEN and removes Carbon Dioxide.
- Provides cells with NUTRIENTS.
- Removes the waste products of metabolism to the excretory organs for disposal.
- Protects the body against disease and infection.
- Clotting stops bleeding after injury.

- transport of oxygen, carbon dioxide and nutrients.
- clotting of open wounds.
- regulation of body temperature.
What is cardiovascular system and its function?

What are the 4 stages of a heartbeat?
The cardiac cycle involves four major stages of activity: 1) “Isovolumic relaxation”, 2) Inflow, 3) “Isovolumic contraction”, 4) “Ejection”. (See Wiggers diagram, which presents the stages, label-wise, in 3,4,1,2 order, left-to-right.)
