Blog 3 Mechanisms That Control Breathing

One major mechanism of breathing is Ventilation. The two are inhalation and exhalation whiach are controlled by the nervous system and respiratory muscles. In inhalation the air moves in causing the lungs and ribcage to expand. By doing this, the diaphram contracts downward because of inhalation. The mechanism of exhalation is Diaphram relaxes upward, the lungs and ribcage compress, and eventually the air is let our through the mouth. I would say that the lungs, oxygen and air ventilation are the major keys when it comes to controlling any humans breathing.
