What is the renal tubule? What structures are found int the renal tubule? What is its purpose? (Anatomy and Physiology)

Structure and function of renal tubule is given below.

Explanation:

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.The components of the renal tubule are the proximal convoluted tubule (PCT), the loop ofHenle, and the distal convoluted tubule (DCT).Urine drains from these pores into the minor calyx that encloses the papilla. Glomerular capsule to PCT to nephron loop to distal convoluted tubule to collecting duct to papillary duct to minor calyx to major calyx to renal pelvis to ureter to urinary bladder to urethra.There are about two million nephrons in each kidney. Nephrons begin in the cortex; the tubules dip down to the medulla, then return to the cortex before draining into the collecting duct. The collecting ducts then descend towards the renal pelvis and empty urine into the ureter.Once the filtrate passes through the thick ascending limb of Henle, it enters the distal convoluted tubule, which is a duct of the renal tubule located in the kidney's cortex that reabsorbs calcium, sodium, and chloride and regulates the pH of urine by secreting protons and absorbing bicarbonate.
