Question

Identify X, Y, and Z.
$\begin{array}{cc}\text{Component of blood}& \text{Function}\\ \left(a\right)\text{X}& \left(i\right)\text{Prevents blood clotting in blood vessels}\\ \left(b\right)\text{Y}& \left(ii\right)\text{Phagocytic in nature and engulf bacteria}\\ \left(c\right)\text{Z}& \left(iii\right)\text{Help in blood clotting}\end{array}$

• A. X: Platelets, Y: Heparins, Z: Monocytes
• B. X: Heparins, Y: Lymphocytes, Z: Platelets
• C. X: Platelets, Y: Neutrophils, Z: Heparins
• D. X: Heparins, Y: Monocytes, Z: Platelets

Answer 1

The correct option is D X: Heparins, Y: Monocytes, Z: Platelets

• Heparin (X) proteins play important role in preventing unwanted blood clotting inside blood vessels.
• Monocytes (Y) are motile leucocytes. They are phagocytic in nature and engulf bacteria.
• Platelets (Z) are involved in blood clotting process. They help to prevent excessive blood loss during injuries.
