Draw one straight line from each component of blood to its correct primary function.
| Component of blood | Primary function |

| Erythrocytes | Transports dissolved carbon dioxide, urea, and digested food molecules |
| Initiates the multi-step cascade that leads to blood clotting | |
| Plasma | Transports oxygen bound to haemoglobin |
