Respiration and Respiratory Systems: Human respiration: GAS EXCHANGE

WebbIn the lungs, oxygen diffuses out of the alveoli and into the capillaries surrounding the alveoli. Oxygen (about 98 percent) binds reversibly to the respiratory pigment hemoglobin found in red blood cells (RBCs). RBCs carry oxygen to the tissues where oxygen dissociates from the hemoglobin and diffuses into the cells of the tissues. Webb17 nov. 2024 · Once in the lungs, oxygen is moved into the bloodstream and carried through your body. At each cell in your body, oxygen is exchanged for a waste gas called … WebbDuring alveolar gas exchange, respiratory gases are exchanged between the air in the alveoli and the blood in the capillaries that surround them. Oxygen and carbon dioxide must diffuse through the respiratory membrane, which is composed of the squamous cells forming an alveolar wall and the squamous cells forming a capillary wall. philip romm md ga
