Question 1

5.5 L

Answer 1

Amount of blood in adult? (volume)

Question 2

Cardiac Output=C.O.=(stroke volume)(Heart Rate)

Answer 2

Cardiac Output Equation?

Question 3

Jan. 23, 2011

Answer 3

coldest day in January

Question 4

Galvanic cell has negative G.Electrolytic cell has positive G, requires voltage to run.ALSO, think electroLYSIS, breaking up, making pure products (like H2)

Answer 4

Difference between Galvanic Cell and Electrolytic cell?

Question 5

No! It does not have that H on the end.

Answer 5

Does an atom with R-O(-) count as protic?

Question 6

w=nFe where n=# electrons, F=Faraday’s constant, e=electromotive force (V, voltage)

Answer 6

Equation for amount of work performed in electrolytric cell?

Question 7

vRMS=sqrrt(3RT/m)

Answer 7

Equation for Root Mean Square Velocity Gas

Question 8

unsaturation=2(#C)+2-(#H) Extended= 2(#C)+N-(#H)-(#X) Nitrogen makes 3 bonds, which is 1 less than the required.Halogens make one bond, which is one less than the required amount. It’s the total # of intended bonds - the total # of actual bond making things

Answer 8

Formula for Unsaturation

Question 9

Stick the object in water, and see what % of it is submerged.

Answer 9

How can you tell the density of an object in comparison to water?

Question 10

take the average of pKa of conjugate acid of weak base, and average with pH of titrant acid.

Answer 10

How do you approximate the pH at equivalence for a weak base titrated by strong acid?

Question 11

Take the average of pKa1 and pKa2.

Answer 11

How do you find the equivalence pH of first proton of diprotic acid?

Question 12

=3/2RT

Answer 12

Kinetic Energy of Gas

Question 13

Zikes! Martian is a Big Giant Nerd!

Answer 13

Mnemonic for embryology stages?

Question 14

just curious, does anyone have a mneomic or easy way to remember what the meso, ecto, and endo -derms develop into? Kaplan’s is pretty good: Endoderm: Think Endernal (internal) lining/layer - Organs: Digestive and Respiratory tract, liver, thyroid, pancreas, and bladder. Mesoderm: Think “Means-O-Derm” (i.e., means of getting around) : Musculoskeletal, circulatory, excretory, and reproductive. Ectoderm: Think “Attract-O-Derm” (things that make you attractive): Eyes, epidermis, inner ears (good listener), nervous system (smarts).

Answer 14

Mnemonic for what tissue is derived from what fundamental layer?

Question 15

Q=DelP[(piR^4)/(8nL)]

Answer 15

Poiseulle’s Law

Question 16

Mitral Valve

Answer 16

Valve into left Atria

Question 17

22.4 L Think two rows of 10 1.0 L bottles, with 2.4 extra

Answer 17

Volume of 1 mol ideal gas at STP

Question 18

Peptide bond, N-C=0 Be very weary of a hydrolysis of glutamine or aspartamine, it will yield glutamate and aspartate

Answer 18

What bond does a hydrolysis affect

Question 19

it does NOT depend on # of electrons that have passed, depends on more intrinsic factors.

Answer 19

What does the EMF of a redox reaction depend on?

Question 20

Vena Cava (think of a cave where you are throwing blue blood into, somewhere in Argentina)

Answer 20

What is blood vessel returning veins to right atria?

Question 21

it is the average of the pKa’s that end up giving the molecule a 0 charge, with one + atom and one - atom.Always has to be the zwitterion form.

Answer 21

What is the pI, in simple relativistic terms?

Question 22

Amount of blood leaving veins and entering arteries

Answer 22

What is Venous return?

Question 23

Endothelial cells

Answer 23

What type of cells line blood vessels?

Question 24

Peptide hormone, just like other hormones of the hypothalamus and pituitary glands.

Answer 24

What type of hormone is oxytocin?

Question 25

Think artERIOLS.(think of a opera composer commanding a flock of bleeding, baseball-cap wearing ORIOLES (which are being controlled).

Answer 25

Which blood vessels are most heavily regulated?

Question 26

Pressure.As evidenced by linearity of P in P=pgh

Answer 26

Which increases linearly, pressure or volume?
