QuestionAnswer
What is the main function of the cardiovascular system? To transport oxygen, nutrients, hormones, and waste products through the blood to maintain homeostasis.
What are the three major components of the cardiovascular system? The heart, blood vessels, and blood.
What is the difference between arteries and veins? Arteries carry blood away from the heart (usually oxygenated), while veins carry blood back to the heart (usually deoxygenated).
What chamber of the heart pumps oxygenated blood to the body? The left ventricle.
What is the function of the valves in the heart? To prevent the backflow of blood and ensure one-way movement through the heart.
What is the largest artery in the body? The aorta.
What is blood pressure? The force of blood pushing against the walls of the arteries.
What is the purpose of capillaries? They are the site of gas exchange — oxygen and nutrients move into tissues, and carbon dioxide/wastes move out.
What is the pacemaker of the heart? The SA node (sinoatrial node) — it starts the heartbeat by generating electrical impulses.
What is the difference between systemic and pulmonary circulation? Systemic circulation: carries oxygenated blood from the heart to the body and returns deoxygenated blood. Pulmonary circulation: carries deoxygenated blood from the heart to the lungs and returns oxygenated blood.
