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.
In the renal medulla are a series of cone-shaped tissue masses called renal pyramids. The tip of the renal pyramid is called the renal papilla, and it helps excrete urine formed in the cortex and medulla of the kidney into the renal pelvis.he renal medulla has several cone-shaped tissue masses called renal pyramids; they sort of look like the Pyramids of Giza lying on their side. The very tip of the Pyramid of Giza is known as the capstone.
