Question

What is the relationship between oxygen and carbon dioxide in the respiration process?

Answer 1

Hint: The respiration process involves the inhalation of oxygen-rich air from the atmosphere to each and every cell of the body and also the exhalation of deoxygenated air rich in carbon dioxide from the cells back to the atmosphere.

Complete answer:
In the respiration process, oxygen and carbon dioxide are related in such a way that as the one moves inside the body at the same time the other rushes outside of the body. This means that we breathe in air containing oxygen that reaches the alveoli in our lungs where it diffuses into the blood through which it is carried to the heart. At the same time, carbon dioxide present in the blood diffuses into the alveoli of the lungs from where it is removed from the body when we exhale. Carbon dioxide gets collected from the cells by the blood during the distribution of oxygen to the cells. This process is called the exchange of gases.
The process or exchange occurs simultaneously.

Additional Information:
-Oxygen from the outside air is supplied by our lungs to the cells through the blood along with the cardiovascular system of our body to enable us to obtain energy.
-When we inhale or breathe in, oxygen enters the lungs and diffuses into the blood. Then through the blood, it is taken to the heart and pumped into the cells.
-At the same moment, the carbon dioxide which is the waste product from the breakdown of sugars in the cells of the body diffuses into the blood and later it diffuses from the blood into the lungs and is expelled as we exhale or breathe out.
-One gas oxygen is exchanged for another gas that is carbon dioxide. This exchange of gases takes place both in the lungs during external respiration and in the cells during internal respiration.
-The exchange of gases between alveoli and blood vessels occurs through diffusion. For this, the alveoli are intensely folded and it results in increased surface area for easy diffusion.
-Exchange of gases between blood vessels and alveoli takes place through diffusion followed by exhalation.

Note:
-The oxygen moves into the cells where cellular respiration takes place and energy is produced. The carbon dioxide released moves into the blood and is carried to the lungs.
-During the breathing cycle the lungs always contain a residual volume of air so that continuous inhalation and exhalation should take place. This gives sufficient time for oxygen to be absorbed in carbon dioxide to be released.
