Respiratory Organ System

Respiratory System is one of the significant bodily systems . It plays a major role inside the circulation of the human body . One affected part of the respiratory system may cause great damages in other bodily processes . Respiratory System keeps the body from continuous accumulation of oxygen and to do away with carbon dioxide . Respiratory system is made of lungs , trachea , bronchi , pharynx , nasal passages and larynx . Lungs are the principal respiratory organs of most non- aquatic vertebrates . Lungs

are enclosed in a cavity of the thorax or chest and are usually paired . In the body the lungs are divided into thousands of microscopic compartments called the alveoli . The movement of the diaphragm and of the rib muscles cause the lungs to expand and contract taking air into the lungs (inhaling ) and forcing it out (exhaling . The walls of the air sacs of the lungs are lined with tiny blood vessels The blood gives off carbon dioxide and takes on oxygen through the thin walls of the capillaries . The blood is then returned of the heart and pumped to the various parts of the body to supply the cells with oxygen The cells then diffuse carbon dioxide into the blood through the capillary walls and the blood passes back to the lungs

In good health , a delicate balance of fluids , electrolytes , and acids and bases is maintained in the body . This balance , or physiologic homeostasis , depends on multiple physiologic processes that...
