Oxygen diffuses into the blood through a process called passive diffusion, driven by differences in partial pressure. Step 1: In the lungs, the partial pressure of oxygen (PO₂) in the alveoli is higher than in the deoxygenated blood arriving from the body. Step 2: This pressure gradient causes oxygen molecules to move from the alveoli, across the thin alveolar and capillary walls, into the blood plasma. Step 3: Most oxygen then binds to hemoglobin within red blood cells, which facilitates the transport of large amounts of oxygen throughout the body. Send me the next one 📸
