Circulatory System Functions
- The circulatory system's main function is transporting blood, nutrients, and oxygen throughout the body.
Components of the Circulatory System
- Central Pump: The heart acts as the central pump for the circulatory system.
- Arteries: Carry oxygen-rich blood away from the heart.
- Veins: Carry oxygen-poor blood back to the heart.
- Capillaries: The smallest blood vessels where oxygen and nutrients are exchanged with body tissues.
- Plasma: The watery component of blood.
Blood Components & Functions
- Red Blood Cells: Transport oxygen to body tissues.
- White Blood Cells: Defend the body against bacteria and infections.
- Platelets: Form clots to stop bleeding.
- Hemoglobin: A protein in red blood cells that carries oxygen.
Blood Vessel Function
- Aorta: The largest artery in the body.
- Veins: Contain valves that prevent blood from flowing backward.
Additional Notes
- The circulatory system is vital for delivering essential substances to cells and removing waste products.
