Question: How is oxygen and carbon dioxide transported in human beings?
Oxygen and carbon dioxide are transported in human beings through the circulatory system, primarily through the blood.
Oxygen is carried by red blood cells in the form of hemoglobin. When red blood cells reach the tissues, they release oxygen, which is used by cells for cellular respiration. The hemoglobin then picks up carbon dioxide, a waste product of cellular respiration, and carries it back to the lungs, where it is exhaled.
In addition to being transported by the blood, a small amount of carbon dioxide is also dissolved in the plasma.
The circulatory system works in conjunction with the respiratory system to ensure a continuous supply of oxygen to the body and removal of carbon dioxide.
