In the renal system, peritubular capillaries are tiny blood vessels that travel alongside nephrons allowing reabsorption and secretion between blood and the inner lumen of the nephron. Peritubular capillaries surround the proximal and distal tubules, as well as the loop of Henle, where they are known as vasa recta. Ions and minerals that need to be saved in the body are reabsorbed into the peritubular capillaries through active transport, secondary active transport, or transcytosis. The ions that need to be excreted as waste are secreted from the capillaries into the nephron to be sent towards the bladder and out of the body. Basically, they reabsorb useful substances such as glucose and amino acids and secrete certain mineral ions and excess water into the tubule.
Where are lymphatic capillaries found in the body? Lymphatic capillaries are found throughout the body, except for the following areas: all avascular tissues (cartilage, cornea, lens, and epidermis), the central nervous system, the spleen, and bone marrow. Describe the structure and function of the lymphatic capillary. Lymphatic capillaries are similar to blood capillaries in structure, but are unique in that they allow interstitial fluid to pass into them, but not out. Instead of intercellular clefts separating adjacent endothe-lial cells, lymphatic capillary endothelium overlaps like shingles, forming a type of one-way valve that allows fluid to move into the capillary only.
