What type of circulation sends blood from the heart to the lungs?

The correct answer, pulmonary circulation, is crucial because it specifically refers to the pathway through which blood is transported from the heart to the lungs and back. In the pulmonary circuit, deoxygenated blood is pumped from the right ventricle of the heart through the pulmonary arteries to the lungs. In the lungs, carbon dioxide is exchanged for oxygen, and the now oxygenated blood returns to the left atrium of the heart via the pulmonary veins. This process is essential for maintaining proper oxygen levels in the blood, which is vital for the body's functions.

Other types of circulation mentioned serve different purposes. Systemic circulation refers to the flow of oxygenated blood from the heart to the rest of the body and then back again, while coronary circulation pertains specifically to the blood supply to the heart muscle itself. Venous circulation generally focuses on the return of blood to the heart from the body, but it does not delineate the specific pathway involving the lungs. Understanding these distinctions is important for comprehending how the circulatory system operates as a whole.
