Four main structures of the urinary system - Answers kidneys, ureter,
urinary bladder, urethra
How do kidneys regulate the blood - Answers Filtration, reabsorption, excretion
Kidneys can regulate water volume in our bodies because they can ________ or _______ the urine -
Answers Concentrate, dilute
Urinary Space - Answers Space between inner lining of glomerulus and outer layer of capsule
renal medulla - Answers inner portion of kidney
nephron - Answers functional unit of kidney
Glomerulus - Answers intertwinning network of capillaries
Renal Corpuscle - Answers Spherical structure
Bowman's capsule - Answers sac-like structure that surrounds the glomerulus
Renal cortex - Answers outer portion of kidney
what is the functional unit of the kidney - Answers nephron
what is the nephron composed of? - Answers Renal Corpsucle and tubule
what are the three structures of the renal corpuscle - Answers glomerulus, bowman's capsule, urinary
space
the renal corpuscle receives blood from the _____ arteriole and leaves through the _____ arteriole -
Answers afferent and efferent
what are the three layers of filtration in the kidney? - Answers glomerulus, middle CT layer, bowman's
capsule
what do the pores in the glomerular endothelial layer prevent from getting into the filtrate? and what
do they allow? - Answers Blood, proteins
how does the podocyte layer (bowman's capsule) differ from the glomerular endothelial layer? -
Answers the podocyte layer only allows water/dissolved solutes through its pores, while other layer
allows proteins
what is the correct order of the three layers
a. endothelial, podocyte, connective tissue
,b. endothelial, connective tissue, podocyte
c. podocyte, connective tissue, endothelial
d. podocyte, endothelial, connective tissue - Answers b. endothelial, connective tissue, podocyte
Where does the renal tubule start at? and end at? - Answers Renal Corpuscle, collecting duct
Which is NOT one of the components of the renal tubule?
a. loop of henle
b. proximal convolted tubule (PCT)
c. Bowman's capsule
d. distal convolted tubule (DCT) - Answers C. Bowman's capsule
True or false: The PCT is the first segment of the renal tubule? - Answers True
True or False: The loop of henle is the last segment of the renal tubule - Answers False- its the middle
segment
Waht is the loop of henle composed of? - Answers Descending and ascending limb
the fluid in the loop of henle becomes very concentrated and is not called what? - Answers urea
what is the name of the last segment of the renal tubule - Answers distal convolted tubule
why does further adjustment happen insdie of the distal convolted tubule? - Answers To regulate blood
pressure volume and pH
True or false: the juxtaglomerular apparatus is an endocrine structure - Answers true
When the JG cells release renin this activates angiotensin in the distal convoluted tubule, what does it
do? - Answers It helps regulate blood pressure and blood volume
what is the definition of vasoconstriction - Answers the constriction of blood vessels to increase blood
pressure
what hormone raises sodium absorption to raise blood pressure and volume> - Answers Aldosterone
Atrial natriuretic peptide hormone releases from the atria causes reabsorption at the DCT and secretion
into the - Answers Urine
Name the hormones released after a drop and increase in blood pressure - Answers renin> angiotensin>
aldosterone
ANP
, True or false: the DCT regulates blood pressure by releasing H+ and HCO3- - Answers True
True or false: in the collecting duct ADH stimulates the H2O excretion - Answers False
Where is the binding point for angiotensin? ADH? - Answers The DCT, collecting duct
Renal capsule function - Answers speration of blood and water
Proximal convolted tubule (PCT) - Answers H2O absorption
Distal convolted tubule (DCT) - Answers Na+ reabsorption
Loop of henle - Answers Na+ pumped out (H2O follows)
collecting duct - Answers H2O reabsorption
