- Organs and organ systems
- Tissues make up organs
- An organ is a group of tissues that work together to perform a certain function
- The stomach is an organ made of these tissues:
- Muscular tissue which moves the stomach wall to churn up the food
- Glandular tissue, which makes digestive juices to digest food
- Epithelial tissue, which covers the outside and inside of the stomach
- Organs make up organ systems
- An organ system is a group of organs working together to perform a certain function
- The digestive system is found in humans and other mamals
- The digestive system breaks down food. It does this by releasing digestive juices
- Then the digestive system absorbs the products of digestion
- How organs work in the digestion system
- SALIVARY GLANDS: produce digestive juices e.g saliva
- LIVER: Produces bile
- PANCREAS (a gland) : Produces digestive juices
- SMALL INTESTINE: Digests food and absorbs soluble food molecules, e.g gluscose
- LARGE INTESTINE: Absorbs water from undigested food, leaving faeces.
