in ionic bonds are electrons exchange or shared?

A

exchanged

29
Q

in covalent bonds are electrons exchange or shared?

A

shared

30
Q

what is an example of ionic bond

A

salt

31
Q

what is an example of covalent bond

A

water

32
Q

Electrical gradient is

A

charged particles moving toward he opposite charge “opposites attract”

33
Q

concentration gradient

A

the concentration of particles is higher in one area and lower in another

34
Q

Examples of passive transport

A

Diffusion

Facilitated diffusion

35
Q

Examples of active transport

A

primary active,
secondary active
endocytosis exocytosis

36
Q

Osmosis is

A

diffusion of water across a membrane

37
Q

Osmolarity is

A

Measure of solute concentration

38
Q

tonicity is

A

effect a solution has on a cell

39
Q

What would decrease passive transport into a cell

A

No concentration

40
Q

What is the normal range of blood pressure

A

90/60mmHg to 130/85mmHg

41
Q

Mean arterial blood pressure (MABP)normal operating range

A

70-100mmHg

42
Q

What is blood glucose

A

primary fuel to make ATP

43
Q

What is the normal blood glucose range?

A

4-6mmol/L

44
Q

hypotonic is when …. and what happens to a cell

A

solutions cause water to move into a cell

- cell then swells up

45
Q

Hypertonic is when … what then happens to a cell structure

A

solutes cause water to leave cell

- cell will shrink

46
Q

What is the normal ECF osmolarity for blood

A

285-300mosmol/L

47
Q

Hypo-osmotic means that there are how many solutes

A

hypo-cold (temp becomes less). therefore LESS solutes

48
Q

Iso-osmotic means that their is how many solutes?

A

iso - same

49
Q

Hyper-osmotic means that their are how many solutes

A

hyper - more solutes

hyper- getting MORE excited

50
Q

In water (hypo-osmotic) do blood cells bursts?

A

Yes

51
Q

What is the maintained core body temp

A

37 degrees C

52
Q

A

Albumin

53
Q

What blood transport maintains blood volume

A

Albumin

54
Q

Albumin is a form of blood transport what is another

A

Hemoglobin

55

enchances blood clotting process

57
Q

injury repair: platelets

A

forms a plug at wound to stop bleeding

58
Q

Injury repair: erthyrocytes

A

red blood cells gets caught in mesh to stop bleeding

59

Iso-osmotic solution:

A

any solution with an osmolarity equal to 300mosmol/L

e.g. NaCl

63
Q

Hyper-osmotic solution:

A

any solution with an osmolarity more than 300mosmol/L

e..g NaCL solution with 300mmol/L (as you double it)

64
Q

A solvent

A

is a liquid that can dissolve other substances to create a solution. E.g. water

65
Q

A solute

A

is a dissolved substance within a solution. E.g. NaCl

66
Q

A solution

A

is created by the combination of a solvent and solutes. For example a sodium-chloride solution is created when NaCl is added to water.
