Physiology
Fluids are filtered through the kidneys and the filtrate is converted to urine. Urine is mostly water and urea, which is a metabolic by-product of protein metabolism, and electrolytes
Urination is mediated by voluntary and involuntary nervous system actions:
- L1-L3 forms the sympathetic branch
- S2-S4 forms the parasympathetic branch - visceral and afferent pathways
