6 primary functions of digestive system: 1. Ingestion- food intake 2. Secretion 3. Digestion- mechanical & chemical breakdown of food Mechanical Mastication- first step. Enables mixing with saliva to form bolus to be swallowed. Regulated by CNS. Deglutition Mixing/Churning Peristalsis- movement of muscles within GI tract that facilitates movement of food Chemical- Hydrolysis (using H2O) of macromolecules into monomers (residues) carried out by digestive enzymes produced by salivary glands

components of ‘Chain of Infection’ with suitable example. *Infectious agent: microorganism causes diseases such as bacteria‚ virus‚ paeasite and fungi. * Reservoir: natural environment that the pathogen requires for survival such as water‚ food or human feces. *Portal of exit. This link is needed for the pathogen to leave the reservoir for example blood‚ urinal track‚ respiratory track or body fluids. *Mode of transmission. The pathogen can be transmitted either directly or indirectly for example as environmental
