Answer:

A nephron is the basic structural and functional unit of the kidneys that regulates water and soluble substances in the blood by filtering the blood, reabsorbing what is needed, and excreting the rest as urine

A nephron is the structure that produces urine in the process of removing waste and excess substances from the circulation. Around 1,000,000 nephrons are found in each human kidney. Primitive fish kidneys (pronephros), amphibian larvae, and embryos of more advanced vertebrates have the most primitive nephrons.

The nephrons seen in amphibians' and most fish's kidneys (mesonephros), as well as in the late embryonic development of more sophisticated vertebrates, are only marginally more advanced in structure. Adult kidneys or metanephros of land vertebrates such as reptiles, birds, and mammals have the most mature nephrons.

Functions of nephron :

The fundamental purpose of the nephron is to remove all waste products from the blood, including solid wastes and excess water, to convert blood into urine, and to reabsorb, secrete, and excrete a variety of compounds.

Small molecules are pushed into the glomerular capsules and travel through a winding sequence of tubules as blood travels through the glomerulus at high pressure.

Each tube's cell absorbs various molecules, omitting glucose, water, and other helpful compounds, which is referred to as the ultrafiltrate. The hypertonicity of the ultrafiltrate molecules increases as they go through the tubules, resulting in more water being extracted before it exits the nephrons, from the ultrafiltrate

The blood that surrounds the nephron returns to the body via the renal blood arteries, which are devoid of toxins and other waste products. The ultrafiltrate retrieved is pee, which goes down the collecting duct to the bladder, where it is stored before being discharged through the urethra.
