Study Notes
Human Circulatory System
- Transports oxygen and nutrients through blood to body cells.
- Comprises the heart and blood vessels.
Heart
- Functions as a pump, circulating blood throughout the body.
- Comprised of four chambers:
- Two upper chambers called atria.
- Two lower chambers called ventricles.
Blood Vessels
- Three primary types of blood vessels:
-
Arteries:
- Transport oxygen-rich and nutrient-rich blood from the heart to body cells.
-
Veins:
- Carry carbon dioxide-rich and low-oxygen, low-nutrient blood back to the heart before sending it to the lungs for reoxygenation.
-
Capillaries:
- Tiny blood vessels connecting arteries to veins, facilitating nutrient and gas exchange at the cellular level.
-
Arteries:
Blood Movement
- Blood flows in one direction through arteries and veins, ensuring efficient circulation.
