Serum differs from blood plasma in:
1. lacking globulins
2. lacking albumins
3. lacking clotting factors
4. lacking antibodies
Which one of the following is correct?
1. Serum = Blood + Fibrinogen
2. Lymph = Plasma + RBC + WBC
3. Blood = Plasma + RBC + WBC + Platelets

The haemoglobin content per 100 ml of blood of a normal healthy human adult is:
1. 25-30 g
2. 17-20g
3. 12-16 g
4. 5-11
Globulins contained in human blood plasma are primarily involved in:
1. defence mechanisms of body
2. osmotic balance of body fluids
3. oxygen transport in the blood
4. clotting of blood
The correct statement in respect of protein haemoglobin is that it:
1. Maintains blood sugar level
2. Acts as an oxygen carrier in the blood
3. Forms antibodies and offers resistance to diseases
4. Functions as a catalyst for biological reactions
