Question

describe the process of urine formation in mammals

Answer 1

The kidneys filter unwanted substances from the blood and produce urine to excrete them. There are three main steps of urine formation: glomerular filtration, reabsorption, and secretion. These processes ensure that only waste and excess water are removed from the body.

1. The Glomerulus Filters Water and Other Substances from the Bloodstream

2. The Filtration Membrane Keeps Blood Cells and Large Proteins in the Bloodstream

3. Reabsorption Moves Nutrients and Water Back into the Bloodstream

4. Waste Ions and Hydrogen Ions Secreted from the Blood Complete the Formation of Urine

5. Urine Is 95% Water

Answer 2

The mechanism of formation of urine in mammals

Explanation:-

• Mammals will turn out targeted excrement. The loop of Henle and also the vasa recta play a crucial role within the same.
• The transport of binary compound within the ascending limb of the loop of Henle ends up in a diffusion gradient.
• It's inactive within the skinny region of the loop whereas active within the thick region.
• The hypertonic medulla is created by the urinary organ tubules and also the vasa recta within the following way:-
• There is an energy absorption of carbamide from the grouping duct.
• Passive absorption of water while not NaCl happens within the down limb of the loop of Henle, which helps to concentrate NaCl coming into the ascending limb.
• In the vasa recta, water is absorbed into the blood and also the absorbed matter comes to the interstitium. this can be referred to as a countercurrent exchange mechanism.
• Human kidneys will turn out more or less fourfold a lot of targeted excrement than the initial filtrate that's shaped.
