• Oesophagus is the pipe through which food transports to stomach.
• Killing of the microorganisms takes place in stomach.
• Complete digestion of food and absorption of food takes place in small intestine.

• Digestion - breakdown of food into simpler form
• Absorption - Absorption of food by the cells of our body
• Assimilation - Using the absorbed food by the cells of our body
• Egestion - Removal of faeces
• Liver secrets the bile juice to digest fats in small intestine.
• Villi are the finger like projection on the surface of small intestine, the function of villi is to increase the surface area for absorption of digested food.
• Amoeba ingests its food by using its false feet/pseudopodia and digests food in food vacuole.
