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. WebAlveoli look like clusters of small round fruits. After absorbing oxygen, the blood leaves your lungs and is carried to your heart. From there, it’s pumped through your body to provide oxygen to the cells of your tissues and organs. When cells use oxygen, they produce carbon dioxide and transfer it to your blood. early settlers of pennsylvania
