PROTEIN

Question 4

PLASMA AND ISF ARE SEPERATED BY _____

Answer 4

HIGHLY PERMEABLE CAPILLARY MEMBRANE SO THEI IONIC COMPOSITION ARE SIMILAR.

Question 5

CAPILLARY HAS ___ TO PROTEIN.

Answer 5

LOW TO PROTEIN, HENCE LEAK ONLY SMALL AMOUNT OF IT INTO INTERSTITIAL SPACE AND MOST TISSUES.

Answer 7

• ANTIPYRINE
• DEUTERIUM OXIDE
• TRITIUM OXID

Question 8

STATE 2 MARKERS THAT IS SUITABLE TO BECOME THE ECF MARKER.

Answer 8

ECF MARKER - A MARKER SUBSTANCE THAT DOES NOT PENETRATE THE CELLS.
- INULI
- THIOSULPHATE
- THIOCYANATE

Question 9

STATE 2 MARKERS THAT IS SUITABLE TO BECOME THE PLASMA MARKER

Answer 9

PLASMA MARKER - A MARKER SUBSTANCE THAT CAN STAY WITHIN THE CASCULAR SYSTEM
- ALBUMIN
- EVAN’S BLUE

Question 10

TO MEASURE THE VOLUME OF VIRTUALLY ANY COMPARTMENT IN THE BODY, WHAT THINGS SHOULD BE PROVIDED.

Answer 10

1. AMOUNT OF THE MARKER TAHT IS INJECTED INTO THE BODY IS KNOWN
2. CONCENTRATION OF THE MARKER THAT IS INJECTED INTO THE MARKER IS KNOWN
3. THE MARKER DISPERSED EVENLY THROUGHOUT THE COMPARTMENT
4. THE MARKERS DISPERSED ONLY IN THE COMPARTMENT THAT WANTED TO BE MEASURED

Question 11

WHAT IS OSMOLARITY?

Answer 11

OSMOLARITY: THE OSMOLAR CONCENTRATION OF A SOLUTION IN LITRE OF SOLUTION/ SOLVENT
- IT CAN GET AFFECTED BY THE TEMPERATURE AND PRESSURE.

Question 12

WHAT IS OSMOLALITY?

Answer 12

OSMOLALITY IS THE OSMOLAR CONCENTRATION OF THE SOLUTION IN KG OF SOLUTION/SOLVENT
- IT CAN GET AFFECTED BY THE CONCENTRATION OF A SOLUTION

Question 13

WHAT IS OSMOTIC PRESSURE?

Answer 13

OSMOTIC PRESSURE IS THE PRESSURE THAT IS REQUIRED TO PREVENT THE OSMOSIS OF WATER THROUGH A SEMIPERMEABLE MEMBRANE.

Question 14

WHAT IS ISOTONIC SOLUTION?

Answer 14

ISOTONIC SOLUTION:
- IT IS A SOLUTION IN WHICH THE COCENTRATION OF SOLUTE IS THE SAME AS THE ANOTHER SOLUTION.
- THERE WILL BE NO NET MOVEMENT OF WATER (OSMOSIS)
- THE OVERAL CONCENTRATION IN BOTH SIDES OF THE CELL MEMBRANE IS CONSTANT.

Question 15

WHAT IS HYPERTONIC SOLUTION?

Answer 15

HYPERTONIC SOLUTION:
- IT IS THE SOLUTION IN WHICH THE SOLUTION HAS HIGH SOLUTE WHEN COMPARED TO ANOTHER SOLUTION
- THE WATER FROM THE CELL WILL DIFFUSE OUT AND INTO THE ECF.

Question 16

WHAT IS HYPOTONIC SOLUTION?

Answer 16

HYPOTONIC SOLUTION:
- IT IS THE SOLUTION IN WHICH THE SOLUTION HAVE LOW SOLUTE WHEN COMPARED TO THE ANOTHER SOLUTION
- THE WATER FROM THE ECF WILL DIFFUSE INTO THE CELL CAUSING THE CELL TO INCREASE IN SIZE AND EVENTUALLY LYSED.

Question 17

STATE 3 EFFECT OF ADDING ISOTONIC SOLUTION INTO THE ECF.

Answer 17

1. OSMOLARITY OF THE ECF DOES NOT CHANGES
2. THERE IS NO NET MOVEMENT OF WATER
3. INCREASE IN THE ECF VOLUME.
4. NA+ AND CL- REMAIN IN THE ECF.

Question 18

STATE 3 EFFECT OF ADDING HYPERTONIC SOLUTION INTO THE ECF.

Answer 18

1. OSMOSIS FROM THE CELL INTO THE ECF
2. ECF VOLUME INCREASES
3. OSMOLARITY OF THE ECF INCREASES
4. ICF VOLUME DECREASES
5. OSMOLARITY OF THE ECF AND ICF INCREASES

Question 19

STATE 3 EFFECTS OF ADDING THE HYPOTONIC SOLUTION INTO THE ECF.

Answer 19

1. BOTH ECF AND ICF VOLUME INCREASES
2. ICF OSMOLARITY INCREASES TO A GREATER EXTENT
3. DIFFUSION OF WATER FROM THE ECF INTO THE ICF.
4. OSMOLARITY OF TH ECF DECREASES.
