Crash Course Blood Vessels part 1

What is the function of blood vessels in the circulatory system?

• All of the above

• To maintain blood pressure

• To bring blood back to the heart

• To carry blood away from the heart

What is the role of capillaries in the circulatory system?

• To regulate blood pressure

• To serve as a bridge between arterial and venous systems

• To absorb large pressure fluctuations

• To distribute blood to specific body parts

What is the main difference between elastic arteries and muscular arteries?

• Muscular arteries are able to absorb large pressure fluctuations

• Muscular arteries are pressure reservoirs

• Elastic arteries contain more elastin than muscular arteries

• Elastic arteries have thicker tunica media than muscular arteries

What is the purpose of venous valves in the veins?

• To distribute blood to specific body parts

• To absorb large pressure fluctuations

• To help keep the blood from flowing backward

• To regulate blood pressure

What is the function of capillary beds in the circulatory system?

• To distribute blood to specific body parts

• To regulate blood pressure

• To help regulate body temperature

• To serve as a bridge between arterial and venous systems

What is the role of smooth muscle tissue in arterioles?

• To help regulate blood flow and pressure

• To absorb large pressure fluctuations

• To serve as a bridge between arterial and venous systems

• To distribute blood to specific body parts

What happens to the blood in the capillaries?

• It gets distributed to specific body parts

• It gets rid of carbon dioxide and other waste

• It absorbs large pressure fluctuations

• It gets oxygenated

What is the purpose of the autonomic nervous system in blood vessels?

• To serve as a bridge between arterial and venous systems

• To distribute blood to specific body parts

• To help regulate blood flow and pressure

• To absorb large pressure fluctuations
