Question

Where do ultrafilteration, reabsorption and secretion occur in nephorn ?

Answer 1

Answer:

Where do ultrafiltration, reabsorption and secretion occur in nephron?

Ultrafiltration takes place in the Bowman's capsule

Reabsorption takes place in the proximal convoluted tubule, loop of Henle and the distal convoluted tubule.

Secretion takes place in proximal convoluted tubule and the distal convoluted tubule

Explanation:

The nephron is the basic and functional unit of the kidney. It is made up of the following parts:

The Glomerulus

The Bowman's capsule

The Proximal convoluted tubule

The loop of Henle

The distal convoluted tubule

The collecting ducts and tubules

Ultrafiltration is the process in which blood is filtered in the Glomerulus. The blood filtrate that resembles the plasma enters into the Bowman's capsule. This process takes place in the Glomerulus that has the efferent and afferent arterioles.

Reabsorption the process by which water and important mineral salts are reabsorbed back into the blood from the Glomerulus filtrate.

Secretion the process in which wastes like uric in the blood are moved from the blood stream into the Glomerulus filtrate

Answer 2

Nephrons:

The nephrons are considered as structural and functional unit of kidney.

It is involved in urine formation which happens through three stages namely:

• Ultra filtration

This happens in the Bowman's capsule through the following places:

1. Endothelium of capillaries
2. Basement membrane
3. Epithelial lining of Bowman's capsule.

• Reabsorption

The reabsorption happens through:

1. PCT
2. Loop of Henel

• Secretion

This process occurs through distal convoluted tubule.
