Renal tubules are essential structures in the kidneys. This lesson explores the function of the renal tubule and its parts, including the proximal and distal convoluted tubules, the loop of Henle, and the collecting duct. Learn how these components work together to absorb materials and form urine.elieve it or not, there are about 1,000,000 of these nephrons in each kidney! Regardless, the first section of each individual nephron is called the renal corpuscle and is made up of the glomerulus, which filters the blood, and Bowman's capsule, which collects the ultrafiltrate.
At the middle of this indentation a tube called the ureter leaves the kidney, and nerves, and blood and lymph vessels also lead in and out of the kidney. Each kidney is covered by three layers made out of fat or connective tissue, the so-called kidney capsule (or renal capsule).These layers give the kidney extra stability, protect it from external harm and anchor it in the surrounding tissue.The kidney is surrounded by a thin outer renal cortex.t the middle of this indentation a tube called the ureter leaves the kidney, and nerves, and blood and lymph vessels also lead in and out of the kidney.
