| 1. | red blood cells | 2. | platelets |
| 3. | neutrophils | 4. | basophils |
Thrombokinase:
| 1. | does not allow blood to clot inside the blood vessels |
| 2. | converts inactive prothrombin into active thrombin |
| 3. | acts as a thrombolytic |
| 4. | is required for formation of thrombocytes |
| 1. | The foetus may suffer from severe anaemia and jaundice due to maternal Rh antibodies attacking fetal RBCs. |
| 2. | The mother’s immune system remains unresponsive to Rh-positive RBCs in subsequent pregnancies. |
| 3. | The foetus develops an overproduction of RBCs to counteract maternal antibodies. |
| 4. | The condition only affects the first pregnancy, with no impact on later pregnancies. |
1. Serum amylase
2. A globulin
3. Fibrinogen
4. Albumin
| 1. | Thrombokinase directly converts fibrinogen into fibrin, which forms a clot. |
| 2. | Thrombokinase is an enzyme complex that converts prothrombin into thrombin, which subsequently converts fibrinogen into fibrin. |
| 3. | Thrombokinase prevents clot formation by inhibiting thrombin activity. |
| 4. | Thrombokinase dissolves clots by breaking down fibrin into smaller fragments. |
Name the blood cells, whose reduction in number can cause clotting disorder, leading to excessive loss of blood from the body.
1. Erythrocytes
2. Leucocytes
3. Neutrophils

Clotting of blood involves:
| 1. | Hemolysis of RBCs |
| 2. | Denaturation of albumins by thrombin |
| 3. | Inactivation of plasma clotting factors |
| 4. | Change of fibrinogen to fibrin by thrombin |
