Defence Against Pathogens
Animals
- Skin
- Physical barrier that blocks pathogens
- Contains antimicrobial chemicals
- Mucous Membranes
- Protect body openings
- Secrete mucous which traps and kills pathogens
- Blood Clotting
- Mesh of protein fibres
- Prevent pathogen entry and blood loss
- Inflammation
- Tissue damage increases permeability of blood vessels
- Leaks fluid into surrounding area and isolates the pathogens
- Swelling
- Vasodilation increases blood flow
- More White blood cells
- Tissue damage increases permeability of blood vessels

- Outer layers of skin divide and move to edge of wound
- Expulsive Reflexes
- Automatic response to expel foreign objects, including pathogens
- Coughing and Sneezing
- Skin
Plants
- Physical
- Waxy Cuticle
- Cell walls
- Callose Deposition
- Sieve plate in the phloem are blocked by a polysaccharide called callose. This prevents pathogens from moving through the phloem
- Chemical
- Produce antimicrobial chemicals
- Saponins
- Chemicals that are toxic to insects
- Produce antimicrobial chemicals
- Physical
