Detailed explanation-1: -The capillaries optimise the diffusion rate by receiving a constant blood supply. They also have an average membrane thickness of only 0.6 micrometres and form a network of capillaries over the alveoli.
Detailed explanation-2: -What are capillaries? Capillaries are delicate blood vessels that exist throughout your body. They transport blood, nutrients and oxygen to cells in your organs and body systems.
Detailed explanation-3: -Final answer: The afferent arteriole after leaving the glomerulus forms a dense network of capillaries called secondary capillary network.
Detailed explanation-4: -Development. During early embryonic development, new capillaries are formed through vasculogenesis, the process of blood vessel formation that occurs through a novel production of endothelial cells that then form vascular tubes.
