how does the change in glomerular plasma osmotic pressure affect filtration pressure?
gpop increase=fp decrease and filtration decrease
gpop decrease=fp increase and filtration increase
if change in hydrostatic pressure in bowmans capsule what happens in filtration pressure?
CHP decreases = FP increases and filtration increases
CHP increases = FP decreases and filtration decreases
the amount of filtrate produced by both kidneys in a twenty-four hour period equals what?
out of 180 liters our kidneys filtrate, what happens to most of it?
it is reabsorbed
the outer layer is called?
the inner layer is?
conical masses of tissues seen in the renal medulla are?
the tips of the renal pyramids are?
extensions of the renal cortex into the medulla form structures called?
name the 2 types of nephrons in the kidney.
cortical and juxtamedullary
describe cortical nephron:
all parts of the nephron are located in the cortex or the loop of henle barely dips into the medulla. 80% of nephrons
describe juxtamedullary nephrons:
the loop of henle dips significantly into the medulla. these are necessary for the formation of hypertonic urine. 20% of nephrons
capillary network within kidney
each glomerulus is surrounded by what?
the glomerulus and bowmans capsule together is called?
bowmans capsule is made up of two layers of what?
simple squamous epithelium
glomerular capillaries contain numerous tiny openings in their walls called? what do they do?
fenestrae-makes the glomeruli more permeable than the capillaries of other parts of the body.
this is formed by the combination of the macula densa and the juxtaglomerular cells:
the large smooth muscle cells of the afferent arteriole that come into contact with the macula densa. it secretes renin. what is this?
the distal convoluted tubule of the nephron comes into contact with the afferent arteriole. Where the contact occurs, the epithelial cells of the distal convoluted tubule are narrowed and packed together. these cells make up what?
the expansion of the ureter as it enters the kidneys is?
the renal pelvis
the tube that connects the kidney to the urinary bladder is?
the tube that leads from urinary bladder to exterior area of body. and name 3 parts for a male:
Look in notebook for pictures of a nephron!!!
the pressure exerted by the blood pressure within the glomerulus is? this promotes filtration and goes into bowmans capsule:
GHP - glomerular hydrostatic pressure
the pressure exerted by the solute level in bowmans capsule. it opposed filtration and opposes movement out of glomerulus. what is this?
GPOP- glomerular plasma osmotic pressure
this runs across the top of the renal pyramids seperates the cortex from the medulla is?
this is located in the cortex and form a meshwork:
capillaries that are located in the medulla, and are longer in the length run vertically are called?
the pressure exerted by the filtrate in bowmans capsule. It opeses filtration and opposes movement out of glomerulus. what is this?
CHP-capsular hydrostatic pressure
if filtration pressure drops the body responds by doing what?
