Question

What is glomerular filtration ? describe mechanism of its formation

Answer 1

Answer:

Explanation:Glomerular filtration is a physiological function of kidney nephrons. The ultrafiltrate, which appears in the lumen of the proximal convoluted tubule, is composed of water and solutes that can pass through the filtering membrane of the capillaries. Under physiological conditions, the large molecular weight proteins and blood cells do not pass through the capillary wall and hence do not appear in the luminal fluid. Therefore, glomerular filtration is relatively nonselective.

Answer 2

Answer:

Glomerular filtration is the process by which blood is filtered through the glomeruli to remove waste and excess fluid from the body.

Explanation:

This is how it works:

• Blood Enters the Glomerulus: Blood enters the glomerulus, which is a group of tiny blood vessels called capillaries.
• Filtration occurs: As blood flows through the capillaries, fluid is expelled from the blood vessels into the surrounding space called Bowman's capsule. This is due to the difference in pressure between the blood vessels and the capsule.
• Formation of filtrate: Fluid filtered out of blood vessels is called filtrate.This filtrate contains water, electrolytes, and waste products like urea and creatinine.
• Reabsorption: As the filtrate passes through the renal tubules, some of the water and electrolytes are reabsorbed into the bloodstream. This process helps regulate the balance of fluids and electrolytes in the body.
• Secretion: In addition to reabsorption, some substances, such as drugs and other toxins, are actively secreted into the renal tubules.
• Urine formation: After passing through the renal tubules, the remaining fluid collects in the collecting tubes and is eventually excreted from the body as urine.
