2. Immunity:

• The gamma globulin produce antibodies which provide immunity to the body.

3. Transport:

• Plasma proteins helps in transport of certain substances like hormones, enzymes etc.

4. Erythrocyte sedimentation Rate (ESR):

5. Reserve Function:

• Plasma proteins stores proteins and break them into amino acids when needed by the body.

Question 2. Serum.
Answer:

Question 3. Starling’s Hypothesis.
Answer:

• It is to determine the net filtration pressure.
• According to the Starling’s hypothesis, the net filtration through capillary membrane is proportional to the hydrostatic pressure difference across the membrane minus the oncotic pressure differences.
• These pressure are called Starlings forces.
