heart
The carrier of food and gases to the body cells is the bloodstream. Oxygen and nutrients are transported by red blood cells, while carbon dioxide and other waste products are carried away from the cells by the bloodstream.
Blood Cells.
The exchange of gases between the blood and the body cells is known as internal respiration. This process involves the uptake of oxygen by the cells and the release of carbon dioxide into the bloodstream to be transported to the lungs for elimination.
Other than as free gases in the lungs, gases are either dissolved in the blood plasma or absorbed by the protein hemoglobin found in red blood cells. Hemoglobin mostly absorbs oxygen, carbon monoxide, or carbon dioxide and carries these gases between the cells and the lungs. Nitrogen gas dissolves in blood plasma and body tissues, and is also a metabolic byproduct (as urea).
Heat is carried away from blood cells. The blood acts as a carrier of heat from the body's core to the skin, where heat can be released to the environment. This helps regulate body temperature and prevent overheating.

Depending on the source, that figure varies from 50 to 75 trillion cells. ---- Answered by Courtney!
