The cell membrane simply accepts it when it is delivered through the blood.
Oxygen and carbon dioxide move into and out of cells through diffusion. Oxygen diffuses into cells to be used in cellular respiration, while carbon dioxide diffuses out of cells as a waste product of this process.
'c' heart pumps oxygen rich blood, 'a' oxygen rich blood arrives at capillaries, 'd' oxygen moves through capillary walls, 'b' oxygen enters body cells.

The process is called cellular respiration. Oxygen moves out of the cells during the final step of cellular respiration, where it is used to produce energy (ATP) through a series of chemical reactions.
Oxygen diffuses from the tracheoles into the body cells through a process called passive diffusion. This process relies on a concentration gradient, where oxygen moves from an area of high concentration in the tracheoles to an area of low concentration in the body cells.

Oxygen and carbon dioxide move into and out of cells through diffusion. Oxygen diffuses into cells to be used in cellular respiration, while carbon dioxide diffuses out of cells as a waste product of this process.
capilaries
Oxygen diffuses into cells. Carbon dioxide diffuses out.
Capillaries
Oxygen is the gas that usually passes into cells. It moves by diffusion from the bloodstream.
Sponges get oxygen by taking water through it's pores. The water moves over cells inside the sponge and oxygen in the water moves into the sponge's cells.
The circulatory system (blood) moves oxygen through the body to the cells.
Oxygen moves through the body via the bloodstream, carried by red blood cells. It is inhaled into the lungs, where it diffuses from the alveoli into the bloodstream, and then transported to tissues and organs where it is exchanged for carbon dioxide to be exhaled.
'c' heart pumps oxygen rich blood, 'a' oxygen rich blood arrives at capillaries, 'd' oxygen moves through capillary walls, 'b' oxygen enters body cells.
capilaries
Oxygen leaves the circulatory system and enters cells through the process of diffusion. This occurs at the capillaries where oxygen moves from an area of higher concentration in the bloodstream to an area of lower concentration in the cells. This process is essential for providing cells with the oxygen they need for cellular respiration.
