How does O2 move from the capillaries to the tissues? How does a rise in metabolic rate in the tissues affect this process?
What will be an ideal response?
Answer: O2 moves by diffusion from the capillaries into the tissues. There is a concentration gradient, with O2 being lower in the tissues due to O2 consumption by the mitochondria. If the tissues increase their metabolic rate, more O2 will be consumed, and the concentration gradient becomes greater, so more diffusion occurs.
