Kidneys and Urinary System :recycle:
Formation of Urine
ii.Ammonia ---> urea
iii.Urea travels in blood to kidney
i.Amino acids ---> ammonia
Urinary System
1.Kidneys excrete nitrogenous waste
2.Maintain blood volume
Water balance regulation
iii.ADH travels in blood to nephron
ii.Low water, pituitary releases ADH
i.Brain monitors water content of blood
iv. ADH causes more water to move from urine back into blood
Kidney stones
Uric acid
Bacteria
Calcium
Major organs
Ureters
Bladder
Kidneys
Urethra
Urine formation by Nephron
ii.Glucose and aminon acid reabsorbed into blood
iii. Some water reabsorbed into blood
i.Blood pressure forces water ... into nephron
iv.Urine is urea and salt concentrated in water
Alcohol effects
Without ADH, higher amounts of water stay in the urine
Urine with high concentrations of water leaves the body
i.Alcohol suppresses ADH production by the pituitary
Causes Incontinence
Urge
Overflow
Stress
Problems of Urinary Tract
ii.Infect urethra ->bladder -> kidneys
