Cell organisation

• What are large multicellular organisms made up of?


  Organ systems
• What are the building blocks that make up all living organisms?

  Cells
• How do specialised cells contribute to the structure of multicellular organisms?


  They form tissues which then form organs to carry out specific functions
• What is the role of different systems in large multicellular organisms?


  They are responsible for exchanging and transporting materials
• What is a tissue?


  A group of similar cells that work together to carry out a function
• What is an organ?


  A group of tissues
• What is the digestive system?


  An organ system found in humans and other mammals
• What are the main organs of the digestive system?


  • Salivary glands
  • Liver
  • Stomach
  • Pancreas
  • Large intestine
  • Small intestine
• What are the functions of the main organs in the digestive system?

  • Salivary glands: Produce digestive juices
  • Liver: Produces bile
  • Stomach: Digests food
  • Pancreas: Produces digestive juices
  • Large intestine: Absorbs water from undigested food
  • Small intestine: Digests food and absorbs soluble food molecules (e.g., glucose)
