ANATOMY

Detailed explanation-1: -The exchange of gases between the blood and tissue cells is internal respiration. Finally, the cells utilize the oxygen for their specific activities: this is called cellular metabolism, or cellular respiration. Together, these activities constitute respiration.

Detailed explanation-2: -Cellular respiration is the process in which the cells of all living things break down the organic compound glucose with oxygen to produce carbon dioxide and water. Oxygen is brought into the body with each inhalation, and carbon dioxide is released with each exhalation.

Detailed explanation-3: -The process of gaseous exchange All forms of respiration require some form of gaseous exchange. In aerobic respiration, oxygen must enter our blood and carbon dioxide must leave the blood through our lungs. Gaseous exchange is the exchange of oxygen and carbon dioxide across a respiratory surface.

Detailed explanation-4: -The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

Detailed explanation-5: -Respiration is the process in which food is oxidized to release energy. Complex organic compounds are converted into simpler ones, e.g glucose into CO2 water and energy released. Gaseous exchange is the diffusion of gases from a region of higher concentration to a region of lower one.
