Question 1

components of plasma

Answer 1

intercellular fluid, interstitial fluid, extracellular fluid composed of plasma and transcellular fluid

Question 2

function of interstitial fluid

Answer 2

transport of oxygen nutrients and waste products throughout the body
aka lymph when drained into the lymphatics

Question 3

plasma function

Answer 3

liquid component of blood

Question 4

transcellular fluid function

Answer 4

ocular fluid and cerebrospinal fluid composed of

Question 5

difference between plasma and interstitial fluid

Answer 5

more protein present in the plasma

Question 6

how to obtain plasma

Answer 6

centrifugation of the blood

Question 7

what is seen between red cells and plasma

Answer 7

Buffy coat

Question 8

composition of Buffy coat

Answer 8

made of leukocytes and platelets

Question 9

apherisis

Answer 9

taking blood from volunteer and centrifugation to separate desired components and returning the rest back to volunteers

Question 10

difference between plasma and serum

Answer 10

serum id obtained by letting blood clot trapping the platelets in the clot
plasma has coagulation factors while serum does not

Question 11

major type of plasma proteins-2

Answer 11

serum albumin and globulin

Question 12

function of serum albumin

Answer 12

transport of lipids, hormones and ions and maintains osmotic pressure

Question 13

globulins subdivision-3

Answer 13

alpha, beta and gamma

Question 14

alpha-1-globulin function

Answer 14

represented by alpha-1-antitrypsin protease inhibitor to protect tissues e.g neutrophil elastase during inflammation

Question 15

alpha-2-globulin function

Answer 15

divided into 2
haptoglobin:binds to haemoglobin forming happy-haemoglobin complex to be removed by spleen
&2-macroglobulin: protease inhibitor which inactivates fibrinolysis

Question 16

beta-globulin function

Answer 16

represented by C3 and C4 complements

or protein transferrin which is needed for iron transport

Question 17

gamma-globulin function

Answer 17

immunoglobulin and C-reactive protein involved in immune system activity

Question 18

describe the Na+-K+ ATPase

Answer 18

3 Na+ out and 2 K+ in

uses the energy from the breakdown of ATP

Question 19

describe the electrolyte composition in and out of cells

Answer 19

more Na+ outside the cell
more K+ inside the cell
highest conc difference with more Ca2+ inside the cell
more Mg2+ inside the cell
more Cl- inside the cell
