Blood compostion

Question 1

Plasma osmolarity is

Answer 1

300 mOsmol/L

Question 2

Define osmotic pressure

Answer 2

the pressure necessary to prevent net movement of water (in osmosis )

Question 3

Nomral plasma osmotic pressure

Answer 3

5540mmHg

Question 4

Plasma osmotic pressure types

Answer 4

Crystalloid osmotic pressure and colloid

Question 5

what is the Crystalloid osmotic pressure

Answer 5

it is the pressure generated by electrolyte mainly NaCl , this pressure control water distributibn betweeen inside and outside of cells . hence its improtant in manintaing fluid balance acroos cell membrane

Question 6

colloid osmotic pressure what is it

Answer 6

it is the pressure generated by plasma proteins mainly (albumin) , this pressure control water distributibn betweeen inside and outside of blood capillaries , its normally about 25mmHg which is 0.5% of total osmotic pressure
