Question

which factor is responsible for the formation of concentrated urine? ​

Answer 1

The answers are loop of Henle and Anti-Diuretic Hormone (ADH).

The factors that are responsible for the formation of concentrated urine are loop of Henle and Anti-Diuretic Hormone.

The loop of Henle creates a negative or low water potential in the medulla tissues so that more water gets absorbed from the fluid present in the collecting duct.

The Anti-Diuretic Hormone alters the permeability of the collecting duct walls. When the blood as low water potential, the posterior pituitary releases ADH because the neurosecretory cells in the hypothalamus get stimulated.

Answer 2

Maintaining hyperosmolarity towards the interior medullary interstitium in the kidney is responsible for the formation of concentrated urine

Explanation:

• Urine is used to expelling wastes such as urea, ammonia, and uric acid. In addition, potassium, sodium, and calcium ions are expelled in the urine.
• Humans are known as ureotelic because urea is the most common component in urine.
• The term "concentrated pee" refers to urine that has a higher solute concentration than water.
• Sugars, salts, and proteins are dissolved particles that make up the solutes.
• Different processes absorb all of these substances back into the body.
• A loop of Henle and antidiuretic hormone are the factors responsible for the generation of concentrated urine.
• The Henle loop causes the medulla tissues to have a negative or low water potential, allowing them to absorb more water from the fluids in the collecting duct.
• The close closeness of the loop of Henle and the vasa recta, as well as the fluid countercurrent between them, contributes to maintaining a rising osmolarity towards the inner medullary interstitium.
• The medullary interstitium maintains a concentration gradient thanks to this mechanism.
• Because of this mechanism, the concentration gradient in the medullary interstitium is maintained, and human urine is typically four times more concentrated than the initial filtrate.
