Question

What are nephrons how do they help in excretion of waste fast

Answer 1

A nephron is responsible for removing waste products, stray ions, and excess water from the blood. The blood travels through the glomerulus, which is surrounded by the glomerular capsule. As the heartpumps the blood, the pressure created pushes small molecules through the capillaries and into the glomerular capsule. This is the, more physical function of the nephron. Next, the ultrafiltrate must travel through a winding series of tubules. The cells in each part of the tube have different molecules that they like to absorb. Molecules to be excreted remain in the tubule, while water, glucose and other beneficial molecules work their way back into the bloodstream. As the ultrafiltrate travels down the tubules, the cells become more and more hypertoniccompared to the ultrafiltrate. This causes a maximum amount of water to be extracted from the ultrafiltrate before it exits the nephron. The blood surrounding the nephron returns to the body via the interlobular vein, free of toxins and excess substances. The ultrafiltrate is now urine, and moves via the collecting duct to the bladder, where it will be stored.

Answer 2

Hey, here is your answer

Inside the kidney, there are millions of microscopic tubular structures called renal tublues or nephrons. Each nephron starts as a cup like Bowman's capsule which continues behind as a narrow tubule. The tubule is convoluted and opens into a collecting duct. All the collecting ducts then open into the renal pelvis which leads into the ureter.

The main function of the nephron is to filter the blood, purify it and to produce urine. The nephrons remove the waste substances from the blood and convert it into urine.
