Question 1

Oxygenation

Left Vs Right

Answer 1

Patients Right is Deoxygenated

Patients left is Oxygenated

Question 2

Amplitude of a wave

Answer 2

Height of the wave

Question 3

1 Ms to seconds

Answer 3

3 decimal places

Question 4

Congigate base

Answer 4

A more general definition is that a conjugate base is the base member, X-, of a pair of compounds that transform into each other by gaining or losing a proton. The conjugate base is able to gain or absorb a proton in a chemical reaction. The conjugate acid donates the proton or hydrogen in the reaction

Question 5

Strong Acid - Conjugate Base = weak

Weak Acid - Conjugate Base = Strong

Answer 5

X

Question 6

Low pka - Strongest Acid

High pka - Weakest Acid

Answer 6

X

Question 7

Draw information on diagrams

Answer 7

X

Question 8

H3O+ = H+

Answer 8

X

Question 9

Fluid can be in 3x places in your body

Answer 9

Intravascular - Inside your veins

Intracellular - In your cells

Interstitial - Outside cells and veins - AKA the 3rd space

Question 10

Shunt

Answer 10

In medicine, a shunt is a hole or a small passage which moves, or allows movement of, fluid from one part of the body to another.

Question 11

Why do we have a shunt in our heart as a child?

Answer 11

To avoid sending blood to the lungs as a child because they are not yet oxygenated

Question 12

Pulse

- Pulse rate?

Answer 12

Distance between two peaks of the same amplitude.

Question 13

Frequency?

Answer 13

Wave frequency is the number of waves that pass a fixed point in a given time.

Question 14

Fundamental and resulting resonance

Answer 14

Fundamental - main peak and drop

Resulting resonance - the other peaks

Question 15

COOH

Answer 15

Carboxylic Acid

Question 16

Ends in ‘ose’

Answer 16

It is a sugar

Fructose
Glucose
Ribose

Question 17

Ohms Law

&

Symbols

V=
I=
R=

Answer 17

V = Voltage 
I = Current 
R = Resonance 

V = IR
I=V/R

Question 18

Voltage

Water Analogy

Answer 18

Electric Potential

Potential energy per unit charge - Volts

Water stored in a pipe - open the pipe releases the potential energy.

Question 19

Current

Think water again

Answer 19

How much charge goes past a point on a circuit in a certain time.

C/T -Charge/Time

How much water goes through a pipe in a second.

Question 20

Resistance

*think water

Answer 20

How much the charge flow is impeded

Ohm

A tighter neck on the pipe

Question 21

Battery

Neg/Pos

Answer 21

Electrons want to go from negative to positive

Question 22

What is the flow of electrons + charge?

Answer 22

Electrons flow from - to +

BUT

Franklyn didn’t know that so we still use + to -

Question 23

When resistors are in series just add then up.

Answer 23

X

Question 24

Circuits in series

&

Circuits in parallel

Answer 24

Series - one path for electrons to take

Parallel - more than one path for electrons to take

Question 25

More resistors in parallel results in less resistance

Think more water for pipe to flow

Answer 25

X

Question 26

Resistivity

Represented by Roe

Answer 26

How much a material offers resistance opposite to conductivity

R= Roe L/A

How big is the resistance

Question 27

Capacitor

Answer 27

They store charge

Capacitance - How much can a capacitor store.

Question 28

Capacitors in parallel all add up to their equivalent capacitance

Answer 28

X

Question 29

Dielectric

Answer 29

Non conducting material in between conductors in a capacitor - can become polar
