Table 1: Blood Components
| Component | Function |
|---|---|
| Red Blood Cells | Carry oxygen |
| White Blood Cells | Fight infection |
| Platelets | Help stop bleeding |
| Plasma | Transports nutrients and hormones |
Table 2: Blood Vessel Types
| Vessel Type | Function |
|---|---|
| Arteries | Carry blood away from the heart |
| Veins | Carry blood back to the heart |
| Capillaries | Allow exchange of substances between blood and tissues |
| Arterioles | Regulate blood flow to capillaries |
Table 3: Heart Functions
| Function | Description |
|---|---|
| Systole | Contraction of the heart |
| Diastole | Relaxation of the heart |
| Atrial Systole | Contraction of the atria |
| Ventricular Systole | Contraction of the ventricles |
Table 4: Common Mistakes to Avoid
| Mistake | Correction |
|---|---|
| Confusing arteries and veins | Remember: Arteries carry blood away from the heart, while veins carry blood back to the heart. |
| Misunderstanding the role of platelets | Platelets help stop bleeding by forming clots, not by carrying oxygen or nutrients. |
| Assuming that the circulatory system only transports oxygen | The circulatory system also transports nutrients, hormones, and waste products. |
| Neglecting the importance of capillaries | Capillaries are essential for the exchange of substances between blood and tissues. |
