Answer: The greater distance for diffusion will decrease efficiency for diffusion.
Step-by-step explanation:
The microvascular complications includes symptoms that lead to the damage to the eyes (retinopathy), damage to the nerves (neuropathy). This may also lead to impotence and disorders in diabetes.
This involves the damage to the small blood vessels that includes the veins, capillaries and arterioles. The capillaries becomes abnormally thick this affects the gas exchange process. The distance for diffusion increases as a result of which the efficiency for diffusion decreases.
