WebMay 7, 2024 · Osmosis. Osmosis is a specific type of diffusion; it is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration. Water moves in or out of a cell until its concentration is the same on both sides of the plasma membrane. Semi-permeable membranes are very thin … WebNov 18, 2024 · The blood cells of a person deliver oxygen to their body’s cells. This natural process, which allows a cell to take up nutrients and expel waste, is important for its survival. The cell would quickly die if it did not receive oxygen. It is possible, however, that oxygen diffusion is hampered in some cases. home tapis

"WebGas molecules move down a pressure gradient; in other words, gas moves from a region of high pressure to a region of low pressure. The partial pressure of oxygen is high in the alveoli and low in the blood of the pulmonary capillaries. As a result, oxygen diffuses across the respiratory membrane from the alveoli into the blood.
