Filtration happens separation from solids and fluids
Kidney where is the outside and inside called ?
Outerside is renal cortex
Inside renal medulla
Function of kidney ?
Cleanses blood and produces urine
Maintains ph

Adh and aldosterone hormone
Nephrons ?
Blood processing units which carry out the process that form urine collecting duct collect fluid and carries from nephrons to the renal pelvis
Ureter where is it what does it do ?
Carries urine from the kidney to the bladder
With peristalsis contraction of muscles
Bladder

Aldosterone
Hormone released by adrenal cortext maintains blood volume and bp by absorbing salt and water follows salt
Micturition reflex
Reflex to empty bladder
What is niddm and iddm?
1- no insulin dependant
2 insulin dependant
How does alcohol have a effect on the adh
