Doen’t undergo extra-renal elimination

Question 2

Urea filtration, reabsorption, secretion and extra-renal elimination

Answer 2

Urea is freely filtered at the glomerulus

It is reabsorbed a bit from the renal tubule

It is not secreted into the kidney tubule

It doesn’t go completely to the kidney, about a 1/4 ends up in the gut

Question 3

It is not absorbed from the renal tubule
It is secreted into the renal tubule
It doesn’t undergo extra-renal elimination

Question 4

Answer 4

Age, sex, muscle mass, diet lol

Question 5
