Question

The part of the cardiovascular system that transports oxygen-depleted blood from the heart to the lungs brings oxygenated blood back to the heart is:

• A. Pulmonary circulation
• B. Coronary circulation
• C. Systemic circulation
• D. Single circulatory system.

Answer 1

The correct option is A Pulmonary circulation

The correct answer is option A.

• The cardiovascular system is composed of two circulatory paths: pulmonary circulation, the circuit through the lungs where blood is oxygenated; and systemic circulation, the circuit through the rest of the body to provide oxygenated blood. The two circuits are linked to each other through the heart, creating a continuous cycle of blood through the body.
• Pulmonary circulation: The part of blood circulation which carries oxygen-depleted blood away from the heart, to the lungs, and returns oxygenated blood back to the heart.
• Systemic circulation: The part of blood circulation that carries oxygenated blood away from the heart, to the body, and returns deoxygenated blood back to the heart.
