nephrons
Hollow, muscular sac that stores urine until it is relased.
urinary bladder

Glomerulus
Tube leading from the urinary bladder to the outside.
urethra
blood, sugar, proteins
what factors affect glomerular filtration rate
hydrostatic and osmotic pressure
when substances move from the blood capillaries and into the tubular filtrate
tubular secretion
This surrounds the glomerulus
Bowman's capsule
what substances are reabsorbed (name 3)
glucose, water, amino acids, P, K, Na, Ca
Bedwetting
enuresis
