Questions About the Cardiovascular System Questions
Question 1 of 5
Iron-deficiency anemia:
Correct Answer: D
Rationale: Iron-deficiency anemia, common in chronic blood loss (e.g., menstruation), depletes iron for hemoglobin. It’s more common in women, doesn’t affect leukocytes, and is typically treated with oral iron (injections are rare).
Question 2 of 5
This sets glomerular capillary pressure apart from other capillaries found in the body
Correct Answer: B
Rationale: Glomerular capillary pressure is higher (~55 mmHg) than in systemic capillaries (~25 mmHg) due to the afferent arteriole’s larger diameter and efferent arteriole’s resistance, enhancing filtration for urine formation. Lower pressure (A) is typical elsewhere.
Question 3 of 5
The systemic circulation includes all of the following structures except one. Which is the exception?
Correct Answer: D
Rationale: Systemic circulation involves blood flow from the heart to the body (excluding lungs) and back, including the aorta (A), femoral vein (B), and superior vena cava (C). The pulmonary vein (D) belongs to pulmonary circulation, carrying oxygenated blood from lungs to the left atrium, making it the exception.
Question 4 of 5
Identify the vessels that return blood to the right atrium.
Correct Answer: A
Rationale: The right atrium receives deoxygenated blood from the body via the superior vena cava, inferior vena cava, and coronary sinus (A, drains heart muscle). Pulmonary veins (B, D) return oxygenated blood to the left atrium, and pulmonary arteries (C) carry blood from the right ventricle to lungs.
Question 5 of 5
Define artherosclerosis.
Correct Answer: A
Rationale: Atherosclerosis is the hardening and narrowing of arterial walls (A) due to plaque buildup. It doesn’t harden the heart (B), destroy cells (C), or solely inflame walls (D; inflammation is a factor, not the definition).
