urinary system

4 functions of kidneys 1) regulate blood volume; 2) regulate blood electrolytes; regulate blood pH blood; 3) regulate volume, electrolyte content and pH in tissue fluid
where are kidneys located retroperitoneal
what is the membrane that covers the kidneys called renal fascia
internal structure of the kidneys has two tissue layers and a cavity, what is the outer layer called renal cortex
what is the inner layer called renal medulla
what is the cavity called renal pelvis
each kidney has an indentation where the arteries and the veins exit and enter and it is also where the ureter exits, what is the indentation called hilus
in the renal corpuscle the glomerulus is surrounded by what capsule Bowman's capsule
this expands out with tubules and inside there are foot cells that make pores - between these layers is a fluid that will become urine, what is this fluid called renal filtrate
when the tubules and the renal tubule unite they form what duct Papillary duct
these papillary ducts empty urine into what part of the renal pelvis calyx
what are the 3 steps to the formation of urine - put them in correct order 1) glomular filtration; 2) tubular reabsorption; 3) tubular secretion
we have 4 mechanisms of absorption, during active transport the cells and the renal tubules need what energy to transport materials ATP
during passive transport after positive ions are reabsorbed what else is reabsorbed negative ions
during osmosis what is reabsorbed after minerals water
during pinocytosis proteins are absorbed out by what part of the cell membrane
there are 3 hormones that influence absorption - name the hormones and what mechanisms they are responding to 1) aldosterone - to high potassium, low sodium & low BP; 2) ANH - to high BP and high blood volume; 3) ADH - to low body water volume
the ureters stem from where to where and allow urine to flow kidneys to the bladder
what is it called when the smooth muscle of the ureters contracts peristalsis
what is the smooth muscle of the bladder called detrusor
within the urinary bladder what are the folds that permit the bladder to expand called rugae
urination is also known as micturition
the yellow color of urine comes from the breakdown of bile and is called urochrome
the 1st and most primary evaluation of the urinary system is often done with a simple test called urinalysis
the procedure is used to directly visualize the internal structures of the urethra, the urinary bladder and allows for biopsy is called cystoscopy
if someone has a normal urinalysis this demonstrates 4 things which are 1) proper filtration; 2) proper absorption; 3) proper elimination; 4) precise fluid & electrolyte balance
name 5 characteristics of the urine 1) color; 2)odor; 3) pH; 4) specific gravity; 5) constituents; 6) amount
