It is not a surprise that humans need oxygen in order to survive. What are the benefits that oxygen can provide to the body? Oxygen is needed by the cells because it will promote cell growth and regeneration. Take note that the cells need to be healthy all the time to ensure that people will be in perfect health. Based on the choices that are mentioned above, C would be the best answer.

For A, it is the platelets that are in charge of helping blood to clot. Oxygen does not bring food to the cells too. Carbon dioxide is considered to be a waste product of the body so D is not the best answer also. E describes the process by which oxygen enters the body but that is about it. Oxygen is most important for cell growth.

Oxygen is of extreme importance for the human blood and cells, because oxygen is necessary for the cell growth and energy. Hence, option C would be the correct answer. The number of alveoli in an adult’s lungs is somewhere around 600 million. Upon inhalation of oxygen, it enters our lungs through the mouth/nose and then from the lungs, the oxygen gets diffused into the blood capillaries.

At the same time, the carbon dioxide is diffused out into the lungs. The oxygen gets absorbed in the red blood cells and gets transported to cells throughout the body for cell growth and maintenance
