Question

Answer

Answer

Answer

While we are taking in oxygen(O) and giving out carbo- di - oxide(CO2). this happens in our body with the help of lungs only so A is the answer.

Answer

Lungs and Removal of CO2

The lungs play a crucial role in the respiratory system, which is responsible for the exchange of gases between our body and the environment. One of the main waste products that is removed from our body by the lungs is carbon dioxide (CO2). Let's delve into the details of why CO2 is eliminated by the lungs.

Respiration and Gas Exchange
Respiration is the process by which our body obtains oxygen and eliminates carbon dioxide. It consists of two main steps: inhalation and exhalation. During inhalation, we breathe in air containing oxygen, while during exhalation, we release air containing carbon dioxide.

The Role of the Lungs
The lungs are a pair of spongy organs located in the chest cavity. They are responsible for facilitating the exchange of gases between the bloodstream and the external environment. The lungs contain millions of tiny air sacs called alveoli, which are surrounded by blood vessels called capillaries.

Gas Exchange in the Alveoli
When we inhale, oxygen from the air enters the alveoli and diffuses into the bloodstream. Simultaneously, carbon dioxide, which is a waste product produced by our body's cells, diffuses from the bloodstream into the alveoli. This exchange of gases occurs due to a concentration gradient, where oxygen moves from an area of higher concentration (air in the alveoli) to an area of lower concentration (bloodstream), and carbon dioxide moves in the opposite direction.

Transport of CO2 in the Blood
Once carbon dioxide enters the bloodstream, it binds to hemoglobin, a protein in red blood cells. Some of the carbon dioxide also dissolves directly in the plasma. The blood then carries the carbon dioxide back to the lungs.

Removal of CO2 by the Lungs
During exhalation, the air containing carbon dioxide is expelled from the lungs. The carbon dioxide diffuses from the alveoli into the air in the lungs and is then released through the nose or mouth. This process enables the removal of CO2 from our body.

In conclusion, when we breathe out, the lungs help remove carbon dioxide (CO2) from our body. The CO2 is exchanged in the alveoli, diffuses into the air in the lungs, and is expelled during exhalation.
