Renal/Urinary System Flashcards
what percent of our bodies are made of water (male and female)
male = 60%, female = 55%
what is the ratio of intracellular fluid vs extracellular fluid of our bodies
intracellular = 2/3, extracellular = 1/3
what does the blood expel in the kidneys
excess water, salt, wastes of metabolism, toxins, drugs
how much blood flows through the kidneys per min and how much urine is produced in a day
1200mL, 800 - 2000 mL
what does normal urine contain
water, salts, urea, metabolites, hormones, small proteins
what does abnormal urine contain
large proteins, RBC, glucose
4 major organs of the urinary system
kidneys, ureters, urinary bladder, urethra
what is the location of the kidneys
T12 - L3, 11th and 12th ribs, retroperitoneal
3 regions of a kidney
cortex, medulla, pelvis
what are the components of the inner medulla
divided into pyramids, each medullary pyramid ends in a papilla
what are the components of the outer cortex
continuous layer, renal columns
what are kidney lobes and how many are there per kidney
a section of kidney including a medulla and the surrounding cortex, made up largely of nephrons, 5 - 11 per kidney
what is the path of urine from a medulla to a ureter (5)
papilla, minor calyx, major calyx, renal pelvis, ureter
where does filtration occur
the cortex
how is urine produced
by filtering waste from the blood into the nephron
