Why do we breathe?
Gaseous exchange is an important process in living things which reduces the accumulation of toxic gases in the body and helps in reducing tension and anxiety in human beings. Breathing involves the exchange of gases where oxygen is delivered to the blood streams in the lungs, and carbon dioxide is removed from the bloodstreams. Air enters the body through the nostrils or the mouth down to the throat; it enters the trachea which is divided into two bronchi. Each bronchus holds the lungs in the left and right side of the chest cavity. The bronchus is further divided into bronchioles, which hold alveoli necessary for the gaseous exchange. This paper will discuss reasons as to why human being do breath.
Every part of the body requires oxygenated blood for effective performance. Breathing facilitates gaseous exchange whereby the carbon dioxide produced in the body during metabolism is removed (Edward R.). Blood delivers carbon dioxide in the capillaries surrounding alveoli in the lungs. Carbon dioxide moves into the lung through the thin membrane of alveoli. The mechanism of exhaling the toxic gas out involves diaphragm which triggers deflation of alveoli thus forcing the carbon dioxide out of the body. The prolonged build of carbon dioxide in the body results to death because of carbon dioxide poisoning.
Conversion of nutrients extracted from food material consumed by a human being into energy requires oxygen. Breathing provides oxygen, which is a necessary element during
Metabolism. Metabolism process uses oxygen gas as a raw material in energy production which as a result produces carbon dioxide as a waste product.
Inhaling and exhaling in a slow, deep and gentle manner helps people to calm and relax. Deep breathing lowers stress in th...
