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.
The capillary also allows waste from the metabolizing cell to diffuse from the tissue spaces into the capillaries for transport by the blood to the organs of excretion. The capillaries are called exchange vessels because they allow for an exchange of nutrients and waste.6 people found this useful.he diameter of the afferent renal arteriole narrows progressively  more and more into the glomerular capillaries, with the same blood  flow, leading to an increase in press â¦ ure within the glomerulus.
