| 1. | Basophils | 2. | Neutrophils |
| 3. | Eosinophils | 4. | Monocytes |
| 1. | Lub | : | First heart sound associated with closure of tricuspid and bicuspid valves |
| 2. | Cardiac output | : | Stroke volume multiplied by heart rate |
| 3. | Dub | : | Second heart sound, due to opening of semilunar valves |
| 4. | Duration of cardiac cycle | : | 0.8 seconds |
| 1. | AV bundle → Bundle of His → SA node → Purkinje fibres |
| 2. | SA node→ Purkinje fibres → AV node → Bundle of his |
| 3. | Purkinje fibres → AV node → Bundle of His → SA node |
| 4. | SA node → AV node → Bundle of His → Purkinje fibres |
| 1. | Blood pressure is measured with an instrument called sphygmomanometer |
| 2. | If the blood pressure of an individual is 140/90 mm Hg or higher it shows hypertension |
| 3. | The normal systolic pressure is 120 mm Hg and diastolic pressure is 80 mm Hg |
| 4. | Hypertension is caused by vasodilation which results in increased resistance to blood flow |
