Oxygen diffuses by from the alveoli into the blood.

The answer should be C, It diffuses from the alveoli into the blood.


Alveoli, also called the air sac, is the place where the oxygen we breathed in is exchanged with carbon dioxide that our body produces. Oxygen is passed into the blood in the capillaries through the process of diffusion, while carbon dioxide is diffused from the blood back to the alveoli, so that we can exhale the carbon dioxide after that.


Both a and b are not right because when we breathe in, the oxygen travels from the trachea to the bronchi, to the bronchiole, and to the alveoli, instead of directly into blood vessels like arteries, capillaries, or veins. d is also not right because the direction is wrong.


Therefore, your answer should be C.

OLEGan [10]

Answer: They lack nucleus and other organelles important for the synthesis of the enzyme.

Explanation:

The main function of the red blood cells is to supply oxygen throughout the body. The oxygen binds to the hemoglobin and travels throughout the body to ensure the supply of oxygen to various organs and more precisely the cells of the body.

The enzymes that is being synthesized inside the body is produced by the help of the gene and nucleus along with the other organelles involved in it.The mature red blood cells lack nucleus in order to increase the surface area for carrying the oxygen.

As there is no nucleus, mitochondria and golgi apparatus in the cell, there is no enzyme synthesis and broke down in the cell.
