The diffusion of oxygen and carbon dioxide at the muscle site is an essential process for muscle activity. Describe how the process of diffusion works at the muscle site with reference to concepts of partial pressure and diffusion gradients. (6 marks)

(6 marks)", "Image ImageDescription": "Oxygenated blood has high PO2 (partial pressure of oxygen) / concentration of oxygen. Low PO2 in muscle cells. Due to muscle cells using oxygen to create energy. Concentration / diffusion gradient means oxygen passes from bloodstream into muscle cell. Partially permeable membrane. Carbon dioxide transported by the same process but in the opposite direction at each site (e.g. low PCO2 in oxygenated blood and high PCO2 in muscle cells).", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
