MICROANATOMY

Detailed explanation-1: -CO2 is transported in the bloodstream to the lungs where it is ultimately removed from the body through exhalation. CO2 plays various roles in the human body including regulation of blood pH, respiratory drive, and affinity of hemoglobin for oxygen (O2).

Detailed explanation-2: -Carbon dioxide (CO2) is a waste product of cellular metabolism. You get rid of it when you breathe out (exhale). This gas is transported in the opposite direction to oxygen: It passes from the bloodstream – across the lining of the air sacs – into the lungs and out into the open.

Detailed explanation-3: -The volume of air inspired or expired during normal respiration is defined as the tidal volume. The average tidal volume of a healthy human being is 500mL/min. Thus, the amount of carbon-di-oxide given out is 500mL/min.

Detailed explanation-4: -Through these tubes, the lungs bring oxygen into the body and remove carbon dioxide from the body. Oxygen is necessary for all functions of your body. Carbon dioxide is a waste product that the body needs to get rid of.
