Stupid physio words

Question 1

what is a colligative property? example?

Answer 1

• property is that is based on the NUMBER of particles in a solution. (so, its NOT based on the size, shape, or charge)
• example: OSMOTIC pressure
• example: if we say there are 10 BOYS at a party, there are 10 PENISES. We don’t care about size, or shape (at least not in this case)

Question 2

tonicity is? example?

Answer 2

• the ability of a molecule to ATTRACT H20 and change cell VOLUME (think hypertonic)
• example: HOT boys have more tonicity to ATTRACT girls to a party

Question 3

colloid osmotic pressure?

Answer 3

• special name for PLASMA protein to pull H20 into INTERSTITIUM
• example: if you advertise free alcohol, people will come

Question 4

solvent drag?

Answer 4

• wherever H20 goes, it brings dissolved PARTICLES with it

- example: wherever Bieber goes, his groupies follow.

Question 5

membrane potential?

Answer 5

• difference in CHARGE between the inside and outside

- example: difference in TEMPERATURE between inside and outside your apartment

Question 6

exteroceptor vs. enteroceptor

Answer 6

• extero = outside sensor (skin temperature)

- entero = inside sensor (blood pH)

Question 7

renal blood flow?

Answer 7

• the AMOUNT of blood that the kidney gets PER MINUTE
• usually, its about 20% of CARDIAC output
• aka 1200 mL / min

Question 8

whats our analogy for these stupid renal things?

Answer 8

• you run a famous strip club/prostitution place in las vegas.
• 20% of the guys walking down your street stop by your place (renal blood flow)

Question 9

GFR?

Answer 9

• glomerular filtration rate = flow of stuff that goes into bowmans capsule
• the number of people that GO INSIDE your place per minute

Question 10

urine flow rate?

Answer 10

• this is the amount of urine produced per minute

- for our analogy its, the number of ORDERS provided per minute

Question 11

hydrostatic pressure?

Answer 11

• pressure of blood in glomerular capillaries

- total number of guys that PASS BY your establishment

Question 12

clearance?

Answer 12

• amount of something excreted per minute
• example: calculate how many blow jobs your girls give per hour!
  ==> 10% of guys that COME IN get blow jobs (GFR)
  ==> your girls fill 100 orders per hour
  ==> your CLEARANCE is 10 blow jobs per hour

Question 13

fractional excretion?

Answer 13

• % of something that is excreted in one pass
• example: % of guys that pay for a lap dance?
  ==> 50 guys walk inside
  ==> 25 order a lap dance
  ==> fraction is 25/50…. 50%

Question 14

filtered load?

Answer 14

• amount of something you get to filter into Bowmans space
• example: how many single guys can you get to come inside your building?
  ==> you get 100 people in your place per minute (GFR)
  ==> 75% of people in las vegas are single men
  ==> you can get 75 single guys inside!
