Breathing and Respiration

Breathing is also known as ‘external respiration’ because it is an external procedure of bringing oxygen into the body and exchanging carbon dioxide through the respiratory organs. The breathing process in all vertebrates is comprised of a high-yielding tubes which connect the nose with the alveoli. Breathing is a continuous cycle in which the amount of respiratory cycles in a minute is referred to as breathing or the rate of breathing. Under normal circumstances the speed and the depth of breathing is controlled by various homeostasis processes to regulate the partial pressure of carbon dioxide levels in the blood.
