Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body's cells. Every three to five seconds, nerve impulses stimulate the breathing process, or ventilation, which moves air through a series of passages into and out of the lungs.
When we breathe, we inhale oxygen and exhale carbon  dioxide. This exchange of gases is the respiratory system's means  of getting oxygen to the blood. The respiratory system also helps  to regulate the acid-base level in the blood.he primary function of the respiratory system is to supply the  blood with oxygen in order for the blood to deliver oxygen to all  parts of the body. The respiratory system â¦ does this through  breathing.
