Detailed explanation-1: -The respiratory system works with the circulatory system to provide this oxygen and to remove the waste products of metabolism. It also helps to regulate pH of the blood. Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body cells.

Detailed explanation-2: -Homeostasis is the process by which the body maintains a stable internal environment. Homeostasis is maintained by the nervous and endocrine systems.

Detailed explanation-3: -The respiratory system brings oxygen into the body from outside the body and then puts it into the bloodstream in the alveoli of the lungs. Then the circulatory system uses the heart and arteries to bring the oxygen-carrying blood to the capillaries that go to the body cells themselves.

Detailed explanation-4: -The pulmonary circulation is a short loop from the heart to the lungs and back again. The systemic circulation carries blood from the heart to all the other parts of the body and back again.

Detailed explanation-5: -The respiratory and circulatory systems work together to maintain homeostasis. The respiratory system moves gases into and out of the blood.
