Study Notes
Blood Vessel Characteristics
- Arteries have the thickest muscular walls, which helps to maintain blood pressure.
- Arterioles are responsible for controlling blood flow, as they can constrict or dilate to regulate blood flow to specific areas of the body.
- Veins act as major reservoirs for extra blood, storing approximately 50-60% of the total blood volume.
Blood Vessel Structure
- Capillaries have the thinnest walls, consisting of a single layer of endothelial cells, allowing for efficient exchange of oxygen and nutrients.
- Veins have low pressure, which is aided by the presence of one-way valves that prevent backflow.
Blood Vessel Function
- Venules are responsible for collecting blood from capillaries, converging to form larger veins.
- Veins carry blood back to the heart, with the main function of returning deoxygenated blood.
- Arteries carry oxygenated blood away from the heart, with the main function of distributing oxygen and nutrients to the body.
Additional Features
- Veins have valves to prevent backflow of blood, ensuring that blood flows in one direction.
- The main function of arteries is to distribute oxygenated blood to the body, while the main function of veins is to return deoxygenated blood to the heart.
