Which of the following best describes the function of the cardiovascular system?
Which of the following best describes the function of the cardiovascular system?
- Filtering air and facilitating gas exchange in the lungs.
- Transporting nutrients and removing waste from tissues. (correct)
- Regulation of body temperature through sweat glands.
- Controlling movement via skeletal muscles.
If a patient has high blood pressure, which type of blood vessel would be most affected?
If a patient has high blood pressure, which type of blood vessel would be most affected?
- Veins, because they carry deoxygenated blood at lower pressure.
- Venules, because they connect capillaries to veins.
- Arteries, due to their role in regulating blood pressure. (correct)
- Capillaries, due to their thin walls.
Which of the structural features allow capillaries to efficiently exchange materials with tissues?
Which of the structural features allow capillaries to efficiently exchange materials with tissues?
- Several layers of smooth muscle to control blood flow.
- A single-cell thick wall. (correct)
- Thick muscular walls that can withstand high pressure.
- Valves that prevent backflow of blood.

Study Notes
- Cardiovascular system explains the general components.
- Demonstrates how the heart structure works
- Compares vessels that make up the vascular system
- Summarises regulation of blood flow and pressure
- Allows understanding of the mechanisms of blood pressure regulation
General components of the cardiovascular system
- Heart pumps blood.
- Blood contains nutrients and waste products.
- Blood vessels include arteries, veins and capillaries.
Vessels structure & function
- Compares vessels to constitute the vascular system
Arteries
- Thick muscle
- Contracts and relaxes.
- Regulates blood pressure.
- Increases and decreases blood pressure (BP).
Vein
- Thin muscle
- Carries deoxygenated blood.
Capillaries
- No muscle
- Exchanges material
- One cell thick
