4.1 quiz Flashcards
ADH is a hormone responsible for
- increasing the permeability of the collecting duct to water
- decreasing the amount of urine
the presence of the hormone ADH in the nephron would result in…
- a more concentrated urine
- a darker colored urine
- a less dilute volume of urine
DNA has a _______ charge
negative
the red end of the electrophoresis chamber has a ________ charge
positive
the black end of the electrophoresis has a ______ charge
negative
when running gel electrophoresis, the wells of the gels should be closer to the _____ (color) end of the chamber
black
during electrophoresis, DNA in the wells will move toward the _______ (color) end of the chamber
red
when blood osmolarity is high, what is produced in the brain?
a feeling of thirst
the hormone ADH makes the collecting duct more impermeable to water
false
where is antidiuretic hormone (ADH) synthesized in the body?
hypothalamus
the functional unit of the kidney is the…
nephron
which structure of the nephron will the hormone ADH interact with?
collecting duct
in the absence of the hormone ADH, a large volume of dilute urine will be excreted from the kidneys
true
moves substances from the renal tubules to the blood capillaries
reabsorption
moves substance from the blood capillaries to bowman’s capsule
filtration
moves substances from the blood capillaries to the renal tubules
secretion
low blood osmolarity will result in the synthesis and release of the hormone ADH
false
where is antidiuretic hormone (ADH) released/secreted in the body?
posterior pituitary
order the correct sequence of urine movement in the urinary system
- kidney
- ureter
- bladder
- urethra
which hormone is most responsible for regulating electrolytes in the body?
aldosterone
which cell receptors are responsible for monitoring blood osmolarity levels?
osmoreceptors
the structure where water reabsorption does NOT occur is…
ascending loop of Henle
most of the reabsorption of substances in the blood (glucose, amino acids, some water) occurs in the…
proximal convoluted tubule
what type of feedback loop does blood osmoregulation represent?
negative
a person who is diabetic would most likely have high amount of what in their urine?
C6H12O6
you observed leukocytes, trace amounts of blood, and crystals in a patient’s urine sample. what is most likely the diagnosis of this patient?
