2What are the three functions of the Kidney?
3Remove Wastes2. Maintain Water Balance3.
Maintain Ion / pH Balance
4Name three components of blood that do not make
it past the glomerular filter.
5RBCs, WBCs, platelets, large proteins
6In osmosis, water moves from an area of ______
concentration to an area of _____ concentration.
7Water moves from high concentration to low
concentration
8Where in the nephron is glucose reabsorbed into
the bloodstream?
9Glucose is actively transported back into the
blood in the proximal tubule
10Why do our bodies need to deaminate amino acids?
11Removal of the amino group occurs so that
proteins can be converted into carbohydrates for
storage
12What is the outer part of the kidney called?
13Renal Cortex
14At approx. what volume does urine storage become
painful?
15Approx. 400 mL
16What specific semi-permeable structure acts as a
high pressure filter?
17The Glomerulus is a high pressure filter
18These structures carry urine from the kidneys to
the bladder
19Ureters carry urine from the kidneys to the
bladder.
20Where in the nephron does the majority of water
reabsorption occur?
21The descending limb of the loop of Henle is the
site of most water reabsorption
22Where does the majority of ACTIVE reabsorption
and secretion occur in the nephron?
23The majority of ACTIVE reabsorption and secretion
occurs in the proximal and distal tubules
24During osmosis, water moves from an area of _____
solute concentration (hypotonic) to an area of
_____ solute concentration (hypertonic).
25Water will move from a hypotonic solution (low
solute) to hypertonic (high solute)
26Name three wastes products removed by the Kidney
27Ammonia- Urea- Uric Acid- H
28Name three substances that are actively
reabsorbed back into the bloodstream
29Na, Glucose, Amino Acids, Vitamins, other
nutrients are all actively transported back into
the bloodstream
30What area of the nephron has the highest
mitocondria concentration and why?
31Proximal and distal tubules have lots of
mitochondria due to the amount of active
transport that takes place
32The word diabetes comes from a latin word
meaning
33 increased urine output
34Why does somebody with diabetes mellitus have
increased urine output?
35Diabetes mellitus higher blood glucose thus
glucose spills over into urine drawing water
with it.
36What is hemodialysis?
37artificial kidney - blood is pumped through a
dialysis machine that removes wastes from the
blood for somebody with a damaged kidney
38What is Diabetes Insipidus?
39Diabetes insipidus is a malfunction of ADH
causing decreased water reabsorption
40When why would somebody undergo peritoneal
dialysis and why?
41When their kidney / kidneys are not functioning
but and require / request more flexibility
42How many people have won the 1 million Deal or
No Deal prize?
430 - Nobody has picked the right case yet.
44Explain the effect of Antidiuretic Hormone (ADH)
45ADH increases water reabsorption
46What size cube has a the largest surface area to
volume ratio 1cm, 10cm, or 1m
47The 1cm cube has the largest surface area to
volume ratio - an important concept in Biology
48What type of food and/or drink is allowed in the
classrooms at MCHS?
49WATER ONLY! (and sometimes doughnuts if there is
enough for the whole class)
50How is aldosterone different than ADH
(antidiuretic hormone)?
51Aldosterone and ADH increase water reaborption,
but aldosterone does so indirectly through the
reabsorption of Na (sodium)
