NEET Zoology Blood Composition MCQ Question
Which of the following statements about blood composition are correct?
Fibrinogens are involved in blood clotting while globulins help in defense mechanisms.
Erythrocytes are the least abundant cells in blood, constituting less than 45 percent.
Plasma contains various minerals and nutrients, but lacks clotting factors.
Albumins play a role in osmotic balance and are the most abundant proteins in plasma.
Correct Answer
Detailed Explanation
Fibrinogens are indeed needed for blood clotting, and globulins are primarily involved in defense mechanisms. Erythrocytes are the most abundant cells in blood, not the least. Plasma does contain clotting factors, making options B and C incorrect. Albumins do help in osmotic balance, but they are not the most abundant proteins; that title belongs to globulins.
