The Mitochondria
Gas exchange occurs through the process of diffusion. Oxygen passes from areas of high concentration in the environment to lower concentration in the cell, while carbon dioxide passes from the cell to the environment. This is facilitated by the phospholipid bilayer of the cell membrane.
Through the cell membrane.
Water, oxygen, co2
Water, carbon dioxide and oxygen can enter a cell through the plasma membrane.
Small uncharged molecules like oxygen and carbon dioxide can pass through a cell using passive transport, which includes processes like diffusion and facilitated diffusion. Water can also pass through a cell membrane through a process known as osmosis.

What_is_the_passage_of_water_through_cell_membranes_calledPassage of water through cell membranes occurs through osmosis.
Oxygen is essential for cellular respiration, the process by which cells produce energy. Oxygen passes through the cell membrane into the cell and is used in the mitochondria to generate ATP, the cell's energy currency. Without oxygen, the cell's ability to produce energy is compromised, leading to cell dysfunction and potentially cell death.
All particles trying to get into the cell must get through the cell membrane. The cell membrane is selectively permeable, which means that it can select what goes in and what goes out. The structure of a cell membrane is called a lipid bilayer, which is two layers of phospholipids.

It is called Diffusion. It is basically what happens when the air passes through your lungs. It cleans out all the bad stuff and brings in the good.
