Answer 1

Two factors  on which re absorption  in kidney depends on

(1) how much excess water is there to be absorbed

and

(2) how much dissolved waste is there to be excreted

Introduction

Formation of urine is a process important for the whole organism. Not only acid-base balance is modulated by it, but also blood osmolarity, plasma composition and fluid volume, and thus it influences all cells in our body.

A healthy adult person produces 1.5-2 liters of urine per day and this process involves three basic mechanisms:

1) Glomerular filtration

2) Tubular reabsorption

3) Tubular secretion

Functional anatomy

The basic functional unit for the urine formation is called nephron. Very important is the arrangement of nephron: it begins with renal corpuscle (Malpighi) that consists of a glomerulus, which is supplied by afferent glomerular arteriole and drained by efferent glomerular arteriole, and Bowman’s capsule (capsula glomeruli, glomerular capsule). Renal tubules have three segments. The proximal tubule, in which we distinguish pars convoluta (initial section) and pars recta, loop of Henle (intermediate tubule), where can be recognized the descending limb and ascending limb (its proximal part is formed by a thick segment of the ascending limb), and distal convoluted tubule (which has conversely first pars recta and then the pars convoluta) that subsequently joins the collecting ducts.
