Describe the role of the organ system listed in the maintenance of homeostasis for each of the following respiratory events:
a. the cardiovascular system in the exchange of oxygen and carbon dioxide in the lungs
b. the muscular system in inhalation and exhalation
c. the cardiovascular system in the transport of gases throughout the body
d. the lymphatic system in the exchange of gases between the blood and cells of the tissues

Explanation:

Homeostasis can be define as the tendency of the body to maintain it's environment constant and stable as compared to the changes occurring in the external environment.

a. The cardiovascular system will exchange gases such as carbon dioxide and oxygen with the body and the external environment. The main requirement of the body is the oxygen which is inhaled and the carbon dioxide is the gas which is produced as waste of the metabolic process which is exhaled out.

b. The muscle of the diaphragm contracts which allows the increase in volume of the thoracic cavity. The muscles helps in inhalation and exhalation. The intercostal muscles present between the ribs helps in enlargement of the chest cavity. They contracts the rib cage that helps in inhalation and when the rib cage expands the process results in exhalation. The inhalation process helps in maintaining the oxygen levels and exhalation maintains the carbon dioxide levels. Thus respiratory system maintains the homeostasis.

c. The cardiovascular system is the organ system that allows the circulation of the blood and transports nutrients like oxygen, carbon dioxide, blood cells, hormones, electrolytes and amino aids to and from the cells. Thus helps in maintaining the homeostasis by regulating the demands of the cells for oxygen and nourishment.

d. The lymphatic system is a network of small tubes called as lymph vessels. These vessels transfers the lymph fluid which transfers gases, white blood cells and nutrients throughout the body. Thus lymph system maintains the homeostasis by the fulfilling the demand of oxygen when body experience scarcity of oxygen.
