- Cell Organisation
- Large multicellular organisms
- Made up of organ systems
- Cells are the building blocks that make up all living organisms
- Specialized cells form tissues, which form organs, which form organ systems
- L.M.O - e.g. humans have different systems inside them for exchanging and transporting materials
- Similar cells make up tissues
- Epithelial tissue is a type of tissue made of epithelial cells. It covers the inside of the gut
- A tissue is a group of similar cells that work together to carry out a funtion
- Tissues make up organs
- An organ is a group of different tissues that work together to perform a certain funtion
- Stomach - organ, Epithelial tissue lines the inside and outside of the stomach
- Organs make up organ systems
- The organ system is a group of organs working together to perform a function
- The digestive system is an organ system found in humans and other animals. It breaks down and absorbs food. Made up of these organs:
- 1. Salivary glands - produce digestive juices
- 2. Stomach - digests food
- 3. Liver - produces bile
- 4. Pancreas - produces digestive juices
- 5. Small intestine - digests food and absorbs soluble food molecules e.g. glucose
- 6. Large intestine - absorbs water from undigested food leaving poo.
- Organ systems work together to make entire organisms
- Large multicellular organisms
