Functions Of Renal Tubules

Question 1

What are the two types of tubules?

Answer 1

Proximal convoluted tubule (PCT)
Distal convoluted tubule (DCT)

Question 2

What is PCT responsible for?

Answer 2

Reabsorption of glucose, amino acids, water

Question 3

What is loop of Henle consists of?

Answer 3

Thin descending part
Thin ascending part
Thick ascending part

Question 4

What is thin descending part responsible for?

Answer 4

Highly permeable to H2O and nearly impermeable to sodium and urea

Question 5

What is thin ascending part responsible for?

Answer 5

Less permeable to H2O and more to urea and sodium

Question 6

What is thick ascending part responsible for?

Answer 6

Impermeable to H2O and urea
Permeable to Na+ Cl and K

Question 7

What is DCT consist of?

Answer 7

Diluting segment
Late distal part

Question 8

What is Diluting segment responsible for?

Answer 8

Impermeable to H2O and urea

Question 9

What does late distal part have?

Answer 9

Aldosterone → causes Na+ reabsorption and excretion of k+ or H+
Antidiuretic hormone ( ADH )→ H2O reabsorption
