Choose the correct option regarding the statements.
1. Plasma constitutes 45% of blood.
2. Albumin is plasma protein involved in osmotic balance.
3. Blood clotting factors are present in blood.
4. Plasma without clotting factors is serum.
5. Minerals are not found in blood.

  1. 1-4 correct, 5 wrong

  2. 1-2 correct, 3, 4, 5 wrong

  3. 2, 3, 4 correct, 1 and 5 wrong

  4. 2 and 4 correct, 1, 3, 5, wrong

  5. 1 and 5 correct, 2, 3, 4 wrong
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
1. Blood plasma is the fluid portion of blood and constitutes about 55- 60% of the blood.
2. Albumin is the smallest protein present in blood plasma. It maintains osmotic pressure of plasma and also maintains osmotic balance of cells and tissue fluids.
3. Blood contains 13 clotting factors which are named in roman numerals from I to XIII. For example, factor I is fibrinogen, factor II is prothrombin and factor XIII is fibrin stabilising factor.
4. Blood plasma without any clotting factor is called serum.
5. Blood contains many inorganic micronutrients called minerals which are essential for normal body functions such as calcium, iron, phosphorus, sodium etc.
Hence, statements 2,3,4 are correct and 1,5 are incorrect.
So, the correct answer is '2, 3, 4 correct, 1 and 5 wrong'.

C Correct answer
Explanation

Globulins, specifically immunoglobulins (antibodies), are essential components of the immune system and are primarily responsible for the body's defense mechanisms.

E Correct answer
Explanation

Fibrinogen and prothrombin are inactive precursors (zymogens) circulating in the blood plasma that are activated during the clotting cascade.

Match the column I (constituent of blood plasma) with column II (its function) and select correct option

I II
(p) Globulins (x) Regulation of membrane permeability
(q) Sodium (y) Clotting of blood
(r) Water (z) Defence and liquid transport
(s) Fibrinogen (w) Solvent for carrying substances

  1. p-w, q-z, r-z, s-y

  2. p-z, q-x, r-w, s-y

  3. p-y, q-w, r-y, s-x

  4. p-w, q-y, r-z, s-w.

B Correct answer
Explanation

Globulins are involved in defense (z), sodium regulates membrane permeability (x), water acts as a solvent (w), and fibrinogen is involved in clotting (y).

Properdin is

  1. Neurohormone for stimulating body activities

  2. Plasma protein that destroys foreign RBC's

  3. Plasma protein involved in defence against certain bacteria and viruses

  4. Both B and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Properdin is a gamma globulin protein present in the serum of blood. Properdin participates in certain immune functions such as it destroys foreign RBC's and is involved in the defense against certain bacteria and viruses.

So, the correct answer is 'Both B and C'.
