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.
1 capillaries are tiny, thin-walled vessels which form a network to take blood through the organsand tissues. 2  veins collect blood from the capillaries in the body and return the blood to the heart.3  The wall of the veins are thin, the blood is at a much lower pressure.rteries, veins and capillaries. There are three main types of blood vessels: 1  arteries take blood away from the heart to the body organs and tissues. 2  The artery wall is thick and muscular so it can withstand the high pressure of the blood being pumped directly from the heart.
