• The kidneys regulate acid/base concentration and water balance in the blood
and discharge metabolic wastes as urine The entire blood volume passes
through the kidneys every three minutes, during which time water and
electrolytes are filtered and selectively reabsorbed to maintain homeostasis
• Each adult kidney is about 11 cm long, 6 cm wide, and 2.5 cm thick, and
weighs about 140 grams
• The urethra drains urine from the bladder; in males, it also carries
semen during ejaculation In women it is 3 cm long, while in men
it is 20 cm long • Because of this, women are more susceptible to
urinary tract and bladder infections • In men, enlargement of the
prostate gland can result in narrowing of the urethral lumen,
producing frequent and sometimes painful urination

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!
