Question

describe the structure of nephron and function of nephron​

Answer 1

Answer:

A nephron is the basic unit of structure in the kidney. A nephron is used separate to water, ions and small molecules from the blood, filter out wastes and toxins, and return needed molecules to the blood. ... The glomerulus is the specialized configuration of capillaries within the nephron that make kidneys possible.

Answer 2

Within the kidney are small functional units called nephrons, which are made up of glomeruli, Bowman’s capsule, proximal convoluted tubule, loop of Henley's loop, distal convoluted loop, and collecting duct.

Steps of urine formation:

Each kidney is made of millions of nephron. Each nephron has a hollow cup like Bowman’s capsule and a long tubule system following it. Arteriole branching from renal artery make bunches of capillaries,one of which is called a Glomerulus. The first step in the filtration process is when the blood enters the Glomerulus, where it is then pumped through the porous walls into the Bowman’s space. This filtered plasma is mainly water, various salts, urea and glucose. The “glomerular filtrate” then passes through the proximal convoluted tubule , Loop of Henle, the distal convoluted tubule so that useful substances are re-absorbed by blood present in the capillaries around them.The liquid is now called urine is concentrated and collected in collecting duct and poured in ureters to be carried to urinary bladder. Urine is passed out through urethra, when the urinary bladder is full and due to pressure there is an urge to do so. Sphincter muscles regulate this process.

Osmoregulation and excretion are intimately related, these processes together maintain homeostasis (i.e. staying the same), and are performed by the same set of organs. The kidney is the major organ of osmoregulation and excretion in vertebrates.
