Answer 10

Occurs in the loop of henle

Question 11

Descending limb

Answer 11

Let’s water in then water leaves nephrons bia osmosis

Question 12

Ascending limb

Answer 12

Lets in ions which diffuses the concentration of salt

Question 13

Distal convoluted tubule

Answer 13

Final reabsorption of ions

Question 14

Gland that produces ADH

Answer 14

Pituitary gland

Question 15

Dehydration in kidney

Answer 15

Pituitary gland releases ADH so less water is lost in urine and more absorbed via osmosis
