Circulatory System Components
The circulatory system is a network of organs and structures that transport blood throughout the body. Its main components include:
Heart
- A muscular organ that pumps blood through the body
- Consists of four chambers: two atria (upper) and two ventricles (lower)
- Valves prevent blood from flowing backward
Blood Vessels
- Arteries: Carry blood away from the heart
- Veins: Carry blood back to the heart
- Capillaries: Tiny vessels where gas exchange occurs
