Digestion

• Mouth- where food enters. It is the first part of the digestive system.
• Salivary glands- produce saliva that contains enzymes (amylase), which break down food.
• Oesophagus- muscular tube that connects the mouth to the stomach. It pushes food down by contractions, called peristalsis.
• Liver- produces bile, detoxifies the blood and processes absorbed foods.
• Bile- neutralises stomach acid, is alkaline and emulsifies fat.
• Stomach- muscular organ where digestion continues. Protease is also produced here.
• Pancreas- breaks down proteins, carbs, fats and where all digestive enzymes are produced.
• Small intestine- produces protease, amylase, and lipase. It is also where small soluble products are absorbed into the blood through the walls.
• Large intestine- processes waste, as faeces pass through, water in absorbed into the blood.
• Rectum- where faeces/stool is stored
• Anus- where faeces leaves the body.
• Gallbladder- stores excess bile before release into the small intestine.
