Detailed explanation-1: -The air we breathe: three vital respiratory gases and the red blood cell: oxygen, nitric oxide, and carbon dioxide.

Detailed explanation-2: -Respiration is the process through which living organisms take in oxygen and give out carbon dioxide to release energy. So, naturally, respiration is a major and vital process of gas exchange. The transport of gases during respiration, both oxygen and carbon dioxide are carried out by the blood cells.

Detailed explanation-3: -INTRODUCTION. Molecular oxygen and carbon dioxide are two gasses that have played a vital role in physiology over the full course of evolution. Due to the pathological threat of conditions such as hypoxia and hypercapnia, it is vital that these gasses are constantly maintained within the physiological range.

Detailed explanation-4: -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-5: -We humans, along with many other creatures, need oxygen in the air we breathe to stay alive. Oxygen is generated during photosynthesis by plants and many types of microbes. Plants both use oxygen (during respiration) and produce it (via photosynthesis).
