Parts of urinary system

Kidneys Ureters bladder urethra
associated nerves and blood vessels

How is urinary homeostasis maintained

Regulates
blood volume, pressure, PH and composition and osmolarity of
ions glucose and excreting wastes producting

3rd week - the mesoderm begins forming the urinary system
Kidneys form first by 3rd month the kidneys begin
excreting urine

Summary of Renal Function

Characteristics of normal urine

Urinalysis

The analysis of the volume and physical, chemical, and microscopic
properties of urine

How much of urine consists of water

about 95%

What can happen to urine in the case of a disease that effects
metabolism or kidney function

Traces of substances normally not present or normal constituents in
abnormal amounts may appear
