- Cell Organisation
- Cells make up all living organisms.
- Specialised cells form tissues carrying out a function.
- Organs are made up of different tissues carrying out a joint function.
- Organ system are groups of organs carrying out a function.
- Digestive Systems to break down and absorb food.
- Mouth breakdown food
- Glands which produce digestive juices.
- E.g. Salivary gland which produces amylase enzymes in the saliva.
- Liver which produces bile that emulsifies fats and neutralises stomach acid.
- The gall bladder stores bile before it gets released into the small intestine.
- The stomach churns up food and has a HCL that kills bacteria and give the right pH for provides protease enzyme (pepsin) to work.
- The pancreas produces protease, amylase and lipase enzymes and releases it to the small intestine.
- The large intestine removes excess water from undigested food leaving faeces.
- The small intestine moves absorbed food, glucose and ions to blood and has a large surface area.
- The rectum and anus get rid of waste food.
- The small intestine moves absorbed food, glucose and ions to blood and has a large surface area.

- Stomach
- Muscular Tissue - moves stomach wall to churn food.
- Glandular Tissue - makes digestive juices to digest food.
- Epithelial Tissue - covers outside & inside the stomach.
- Organ system are groups of organs carrying out a function.
- Muscular Tissues - contracts (shortens) to move whatever it's attached to.
- Glandular Tissue - makes and secretes chemicals like enzymes and hormones.
- Epithelial Tissue - covers some parts of the body e.g. inside the gut.
- Organs are made up of different tissues carrying out a joint function.
