Disease
1.1 Pathogens:
Pathogens are disease causing microorganisms Disease is the symptoms displayed on a
person following an infection, a malfunction of the body or mind Infectious Disease: Caused by
bacterium, virus, fungum transferred from one person to another Non Infectious Disease: A
disease that…

beyond the mucus
· Digestive System:
o Mucus is antiseptic to kill bacteria o Gastric juice contains HCL which has a low pH to kill
bacteria, by denaturing the pathogen's enzymes
and protease which digests the bacterial cell wall which is made up of protein. o Friendly
bacteria in the…

kash G 12M Pathogens cause disease by:
· Damaging host tissue (inhibit the synthesis of DNA,RNA and proteins ­ may break down the
membrane of the host cell)
· Produce toxins (have various effects such as increased water loss from cholera bacteria)
1.2 Data and Disease:
· Epidemiology is the…

G 12M 2.0 - Enzymes and the Digestive
System
2.1 Enzymes and digestion:
The digestive system is made up of one long tube which is an interface to the environment as
food passes into the body through it; which contains glands that produce enzymes.
Major parts of the digestive…

kash G 12M Digestion There are two types of digestion:
1. Physical breakdown 2. Chemical digestion
1. Physical Breakdown:
o Food is broken down into smaller pieces by the teeth o Makes it possible to ingest, and
increases surface area for chemical digestion o Churning of food by stomach muscles…
