Breathing is a mechanical Process. In breathing, an organism takes in oxygen from its environment and released carbon- dioxide. Breathing involves the transport of oxygen and carbon dioxide between the external environment and the body cells. This process is also called pulmonary respiration. • Breathing is the physical process of inhaling oxygen and exhaling carbon dioxide. The mechanism of breathing involves two main processes: inspiration and expiration. Inspiration occurs when the diaphragm and the external intercostal muscles contract. • #medical #shorts #video #biology #shortvideo #animation #3danimation #human #breathing #breath
