  • Digestive System
    • Oesophagus
    • Stomach
      • Muscular sac with an inner layer that produces enzymes
      • It's role is to store and digest food, especially proteins. It has glands that produce enzymes which digest protein
    • Ileum
      • Long muscular tube
    • Large intestine
      • Absorbs water
      • Most of the water that is absorbed is water from the secretions of the many digestive glands
    • Rectum
      • Final section of the intestines
      • Faeces are stored here before periodically being removed via the anus in a process called egestion
    • Salivary Glands
      • Situated near the mouth
      • They pass their secretions via a duct into the mouth. These secretions contain the enzyme amylase, which hydrolyses starch into maltose
    • Pancreas
      • Large gland situated below the stomach
      • It produces a secretion called pancreatic juice. This secretion contains proteases to hydrolyse proteins, lipase to hydrolyse lipids and amylase to hydrolyse starch
