Answer:
Exchange of oxygen and carbon dioxide takes place in the lungs and the blood is now oxygenated (with oxygen). Through the systemic circulation, oxygenated blood travels from the left side of the heart to the other areas of the body. ... This deoxygenated blood again goes back to the right side of the heart.

Answer:
Humans follow double circulation which is when the blood follows two routes – one for oxygenated blood and the other for deoxygenated blood. Hence, the name “double circulation.” The majority of mammals, including humans utilize a double circulatory system.
