Detailed explanation-1: -You have fenestrated capillaries in your kidneys, intestines, pancreas and endocrine glands. These organs need a continuous exchange of nutrients, waste and substances between the capillaries and tissues. The pores in the capillaries make it easier for this exchange to happen.

Detailed explanation-2: -Capillary structure They are composed of a thin layer of epithelial cells and a basal lamina, or basement membrane, known as the tunica intima. There is also an incomplete layer of cells, that partially encircles the epithelial cells, known as pericytes.

Detailed explanation-3: -Capillaries. Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins).
