Final answer:
Red blood cells do not diffuse across the capillary lining driven by their individual concentration gradients.
Step-by-step explanation:
False. Red blood cells do not diffuse across the capillary lining driven by their individual concentration gradients. Instead, they are actively transported through capillaries by the pumping action of the heart and the contraction of smooth muscles in the blood vessel walls. This process is known as bulk flow. Red blood cells have no nuclei and are incapable of undergoing diffusion.
