Answer #1

Answer:urine is formed in kidney through filtration of blood.

Urine formation occurs as a result of these processes,they are

1)Glomerular filtration

2)tubular reabsorption

3)tubular secretion

4)execretion

Glomerular flitration:In this water and smaller solutes forced through capillary wall and pores of glomerular capsule into renal tubule.

Tubular reabsorption:water,glucose and aminoacids,needed ions are reabsorbed from filtrate into tubule cell and then into capillary blood.

Tubular secretion:H+,k+,creatinine and drugs removed from peritubular blood and secreted by tubule cell into filtrate.

Water conservation:removes water from urine and returns it into blood and concentrate the wastes.
