Detailed explanation-1: -This is where gas exchange takes place. The circulatory system, which is made up of the heart and blood vessels, supports the respiratory system by bringing blood to and from the lungs. The circulatory system helps deliver nutrients and oxygen from the lungs to tissues and organs throughout the body.
Detailed explanation-2: -Oxygen moves from the alveoli to the blood through the capillaries (tiny blood vessels) lining the alveolar walls. This process is called diffusion. In the bloodstream, oxygen gets picked up by the hemoglobin in red blood cells. This oxygen-rich blood then goes to the heart, which pumps it to the body.
Detailed explanation-3: -The respiratory and circulatory systems work together to maintain homeostasis. The respiratory system moves gases into and out of the blood. The circulatory system moves blood to all parts of the body.
