- Disease - caused by pathogens
- Pathogens
- Cause infectious diseases
- Penetrate an organisms interface with the environment
- Must enter body to cause disease through an organisms surface of contact with the environment
- Nose, cut, eyes
- Definition: Microorganism which causes disease
- Bacteria, fungi, viruses
- Cause infectious diseases
- Interfaces
- Gas Exchange System
- Air containing pathogens is breathed in
- Trapped in mucus lining the lung epithelium
- Cilia that move/beat the mucus up into the trachea to the mouth to remove it.
- Some pathogens reach the alveoli > invade cells causing damage
- Trapped in mucus lining the lung epithelium
- Air containing pathogens is breathed in
- Skin
- If skin becomes damaged, pathogens enter bloodstream
- Blood clots preventing pathogen entering
- Some enter before it clots
- If skin becomes damaged, pathogens enter bloodstream
- Digestive System
- Food and drink containing pathogens
- Killed by acid in the stomach
- Some survive and pass through the intestines and invade cells of the gut wall
- Food and drink containing pathogens
- Gas Exchange System

- Cause infectious diseases
- Produce toxins
- Bacteria release toxins
- Tetanus produces toxin which clocks function of nerve cells.
- Causes muscle spasms
- Tetanus produces toxin which clocks function of nerve cells.
- Bacteria release toxins
- Damages cells
- Damages Hosts cells which cell pathogen is invading and reproducing inside
- 1) Ruptures and releases nutrients inside of them
- 2) Breaks down nutrients inside the cell for their own use
- Starves and kills the cell
- Replicates inside cells and bursts them when they are released
- Viruses
- Damages Hosts cells which cell pathogen is invading and reproducing inside
- Pathogens
