What is the name of the circulation pathway that describes the flow of blood from the heart to the lungs and back to the heart?

The circulation pathway that describes the flow of blood from the heart to the lungs and back to the heart is known as pulmonary circulation. This pathway is essential because it allows for the exchange of carbon dioxide for oxygen in the lungs. When blood is pumped from the right side of the heart to the lungs, it travels through the pulmonary arteries. In the lungs, the blood releases carbon dioxide and absorbs oxygen. The oxygenated blood then returns to the left side of the heart via the pulmonary veins, ready to be pumped out to the rest of the body.

This process is distinct from other types of circulation, such as systemic circulation, which is responsible for delivering oxygenated blood to the body's tissues and returning deoxygenated blood back to the heart. Coronary circulation specifically refers to the flow of blood to and from the tissues of the heart itself, while cerebral circulation pertains to the blood supply to the brain. Understanding these different circulation pathways is crucial for comprehending how blood circulates in the body and supports various functions.
