The Respiratory System - Essay Example

The paper "The Respiratory System" is an outstanding example of an essay on biology. The respiratory system is one of the major systems of the human body. Any malfunction in the system leads to a wide range of disarray in the normal functioning of other body organs. In case of an infection or asthmatic attack that impairs the normal flow of oxygen in and waste products out of the system, there is a likelihood of somebody developing hypoxemia and respiratory acidosis which affects a number of body systems. At the same time, the heart is overworked in the bid to compensate for the oxygen demands in other parts of the body as a result. Normal metabolism of the cells is affected owing to the fact they are deprived of oxygen, which remains vital in maintaining the basal metabolic rate.

Moreover, through the respiratory system, one can inhale aerosols that are harmful to the human cells and other systems at large. Some of the chemical gases can cause ulceration to the mucosal membrane of the respiratory system while others affect organs like the kidney which cleanings the human blood. At the same time, the respiratory system acts as a passage through which a number of microorganisms enter into the body, hence causing a number of infections to the system. Some of the infections affecting the respiratory system sometimes might spread further into other organs for instance tuberculosis (Cohn and Reinero, 850). Infection to the lungs too can affect a whole range of the respiratory function. The lungs are necessary for the exchange of gases by exchanging carbon dioxide form deoxygenated blood with oxygen from the atmosphere. Thus the respiratory system plays a vital role in the existence of human beings which has to be maintained functional at the optimal possible standards. Read More
