The respiratory system is a vital part of the human body for it supplies oxygen to the different parts of the body which is necessary for survival. As the body’s breathing mechanism, it is composed of the nose, mouth, trachea ( or wind pipe ) which collectively serve as the airway, a pair of lungs and a muscle for respiration, the diaphragm. The respiratory system begins with the nose where air is inhaled and then carried through the nasal cavity into the pharynx. Once air passes through the pharynx, it goes into the trachea, and from there, enters into the lungs. H/T – Pieter van den Assum
