Step 1

Kidney is an important organ of the excretory system and nephron is the basic structural and functional unit of the kidney. As blood passes through the kidneys, it filters the nitrogenous waste to form urine. The processes include glomerular filtration, tubular reabsorption, and tubular secretion. It helps to maintain the homeostasis of the body.

Step 2

e. - 1. Collecting duct

The collecting tube is a long narrow tube that helps to concentrate and transport urine from the nephron. The loss of water takes place in the collecting duct through the aquaporin channels that are controlled by the anti-diuretic hormone (ADH). This makes the fluid concentrated. The urea moves out of the collecting ducts into the interstitial fluid and is excreted as urine.

m. –2. Glomerulus

The glomerulus is the microscopic filter present in nephrons. It lies inside a cup-like sac structure referred to as the glomerular capsule at the end of the nephron. It removes the waste products, ions, and excess water from the blood and returns the required molecules back into the blood.

Step 3

j. - 3. Peritubular capillaries

Peritubular capillaries are the fine network around the renal tubule that allows for the reabsorption and secretion between blood and lumen of the nephron. Each efferent arteriole gets into the capillary network of peritubular capillaries or vasa recta. In peritubular capillaries or vasa recta, the exchange of gases, nutrients, and waste occurs between the kidney and the blood.
