Alveoli: Function, Lung Anatomy, and Causes of Damage

WebIn the lungs, oxygen diffuses out of the alveoli and into the capillaries surrounding the alveoli. Oxygen (about 98 per cent) binds reversibly to the respiratory pigment haemoglobin found in red blood cells. These red blood cells carry oxygen to the tissues where oxygen dissociates from the haemoglobin, diffusing into the cells of tissues.
