kidney

Question 1

Nephron Structures

Answer 1

bowman capsule, glomerulus, PCT, Loop of Henle, DCT, Collecting duct

Question 2

Bowman’s Capsule:

Answer 2

it filters blood plasma and collects the filtrate that will eventually become urine.

Question 3

Glomerulus:

Answer 3

It is responsible for the filtration of blood, where water, ions, and small molecules are filtered out of the blood into the Bowman’s capsule.

Question 4

Proximal Convoluted Tubule (PCT)

Answer 4

After the filtrate enters the PCT, valuable substances like glucose, amino acids, and ions are reabsorbed into the bloodstream.

Question 5

Loop of Henle:

Answer 5

The descending and ascending limbs of the Loop of Henle create a concentration gradient in the kidney, which helps with water and sodium reabsorption. This helps concentrate the urine.

Question 6

Distal Convoluted Tubule (DCT)

Answer 6

In the DCT, further reabsorption of sodium, chloride, and water occurs. This area is also where the effects of aldosterone and parathyroid hormone (PTH) influence the body’s electrolyte and calcium balance.

Question 7

Collecting Duct:

Answer 7

The final site for reabsorption of water, influenced by ADH. It helps in adjusting the final urine concentration before it enters the renal pelvis.

Question 8

Bowman’s Capsule & Glomerulus location

Answer 8

Located superficially in the renal cortex, which is the outermost region of the kidney.

Question 9

Loop of Henle & Collecting Duct location

Answer 9

These are located deeper in the renal medulla, which is the inner portion of the kidney, further from the surface.
