urinary system Flashcards
sturcture of the urinary system
kidney, renal cortex, renal mendulla, ureters, bladder, urethra
kidney
are a pair of organs that filter blood and produce urine
renal cortex
is the outer layer of the kidney that contains the renal pyramids and blood vessels, erythropoietin is stimulated in the production of new red blood cells
renal medulla
the inner layer of the kidney that help to concentrate urine
ureters
are a pair of tubes that carry urine from the kidneys to the bladder
bladder
is a sac that stores urine until is ready to be excreted
the urethra
is a tube that carries urine from the bladder to the outside of the body
function of the urinary system
important for homeostasis within the body it helps the body excrete waste and maintain balance
the structual unit of the kidney is the
nephron
nephrons
are responsible for the filtration of blood by removing wasteand reabsorbing water
glomerulus
is a ball of capillaries that is the site of filtration within the neuron
renal tubule
is a tube that leads from the glarius to the renal pelvis is reponsible for that reabsorption and secreation what remains from the tubule will be carried into the kidney and drained out from the ueters
cardiovascular system
transports blood to the kidneys so that they can filter it
relationship between the cardiovascular and unrinary sytem
work together to maintain homeostasis
the urinary
excretes waste and helps to regulate blood pressure by controlling the volume of blood
kidneys produce
a hormone called erythropoietin that stimulates the production of new red blood cell in the heart
