The human body has non-specific defence systems to prevent pathogens from entering and causing disease.
Draw one straight line from each body defence to its correct function.
| Body defence | Function | |
|---|---|---|
| Mucus in the trachea | Contains enzymes that destroy bacterial cell walls | |
| Neutralises chemical toxins | ||
| Tears | Traps inhaled pathogens and dust | |
| Engulfs and digests pathogens | ||
| Produces acidic oils to kill microbes |
