Kidney is:

Responsible for maintaining homeostasis through water balance, ions levels, urea levels, pH of blood.

1

Flow of Blood in Kidney

Renal Artery
Afferent Arteriole
Glomerulus
Efferent Arteriole
Peritubular capillaries
Renal vein

2

Flow of filtrate

glomerulus
Bow mans capsule
Proximal Convulated Tubule
Loop of Henle
Distal Convulated tubule
Collecting duct
Renal pelvis
Ureter
Bladder
Urethra

3

Filtrate includes

Water
Salts
Amino acids
Fatty acids
Glucose
Urea
Uric acid
Hormones
Toxins
Ions

4

Proximal Convulated Tubule and Loop of Henle

reabsorption of sodium, potassium, chloride and bicarbonate ions
Glucose
Water by diffusion

5

Distal Convulated tubule

Reabsorption of sodium ions
Active reabsorption of water depending on body needs

Secretion of hydrogen and potassium ions, creatinine and certain drugs like penicillin.

6

Haemodialysis

Machine is used to filter blood

7

Peritoneal Dialysis

Fluid low concentration of wastes is infused into peritoneal cavity. Wasted diffuse into the fluid and it is removed from the body.

8

Deamination

Amino groups are converted into urine.
Remaining part of amino acid - carbon and hydrogen is converted into carbohydrates.

Amino Acid + oxygen > carbohydrate and ammonia.

Ammonia and CO2 + energy > urea and acids
