Why nephron is called filtering unit of kidney?

Question

Answer

Nephron is the filtering unit of kidney. It is so called because it filters the blood and removes nitrogenous wastes from it. The harmful products get filtered and useful products are reabsorbed by tubular part of nephron.....

Answer

The primary filtration of blood took place in nephron in which the toxic wastes of our body i.e. nitrogenous wastes are filtered with the help of constituents like bowmen's capsule, glumerulus, and semipermeable membrane of blood capillaries in which important substances are reabsorbed from tubule. That's why we can say that the nephron is the filtering unit of kidney.

Answer

Kidneys are made up pf nephrons so then it work but really nephrons are functioning there

Answer

Nephron is the structural and functional unit of the kidney because it act as a unit of filteration and removes the waste products from blood  inside the kidneys by many processes including ultrafiltration, selective reabsorption and secretion. After these processes, urine is formed.Each kidney possesses a large number of nephrons (approximately 1- 1.5 million).

Answer

**Introduction:**
The nephron is considered the filtering unit of the kidney due to its crucial role in the filtration and processing of blood to produce urine. Each kidney contains approximately one million nephrons, which are responsible for maintaining the body's fluid balance, regulating electrolyte levels, and removing waste products.

**Structure of the Nephron:**
A nephron consists of two main parts: the renal corpuscle and the renal tubule. The renal corpuscle is comprised of the glomerulus and the Bowman's capsule, while the renal tubule is composed of the proximal convoluted tubule, loop of Henle, and distal convoluted tubule.

**Filtration Process:**
The filtration process within the nephron begins at the glomerulus, a network of tiny blood vessels called capillaries. The glomerulus receives blood from the renal artery and high pressure forces plasma out of the capillaries and into the Bowman's capsule. This process is known as filtration.

**Selective Reabsorption:**
After filtration, the filtrate moves into the renal tubule, where selective reabsorption occurs. The renal tubule is responsible for reclaiming valuable substances from the filtrate and returning them to the bloodstream. Essential substances such as glucose, water, ions, and amino acids are selectively reabsorbed through active transport and diffusion.

**Tubular Secretion:**
Tubular secretion is another important process that takes place within the nephron. It involves the transfer of substances, such as hydrogen ions, potassium ions, and certain drugs, from the blood into the renal tubule. This process allows the nephron to actively eliminate waste products and maintain proper pH balance.

**Urine Formation:**
As the filtrate flows through the renal tubule, it undergoes various modifications before it becomes urine. The loop of Henle plays a crucial role in concentrating the urine by creating a concentration gradient in the surrounding interstitial fluid. This allows for the reabsorption of water in the collecting duct, resulting in the production of concentrated urine.

**Conclusion:**
The nephron is rightly called the filtering unit of the kidney as it performs the essential functions of filtration, selective reabsorption, tubular secretion, and urine formation. Through these processes, the nephron helps maintain the body's fluid balance, regulate electrolyte levels, and eliminate waste products. Understanding the intricate functioning of the nephron is crucial for comprehending the kidney's overall role in maintaining homeostasis within the body.

Answer

Nephron is known as filtering unit of kidney because it removes the waste products from blood and forms urine. Each kidney possesses a large number of nephrons

I hope it's helpful for us .....

Answer

Because it removes the waste products from blood.
