PPT-1 Biology Year 9 Digestion and Food

2 The digestive system The digestive system converts foods to simple substances that can be absorbed and used by the cells of the body It is composed of the mouth pharynx oesophagus stomach small intestine and large intestine and is aided by several accessory organs liver gall bladder and pancreas.

How does it change? Your meal has a story to tell about its journey through the digestive tract and the interactions it has with the accessory organs of the digestive system. Your job is to express and illustrate this journey!. Andrew Gabriel and . Tidasate. Success. What exactly is biogas (composition)?. What is the biological process by which it is created?. What type of substance is used in this process?. What are the three stages of the biogas production process?. Tony . Serino. , Ph.D.. Biology 201. Misericordia. University. Digestion. The reduction through mechanical and chemical means (hydrolysis) of complex food substances into simple monomers and their absorption into the internal environment.. . We are going to use household items to model the digestive system..  . Digestion Lab. Substances in food that provide raw materials and energy the body needs to live. Our digestive system turns the chemical energy in these nutrients into energy we can use. Digestive System Mouth Digestion begins in the ________ . ________ begins the process of digestion __________________- is the physical breakdown of large pieces of food into smaller pieces. __________________- large food molecules are broken down into smaller food molecules with the help of different enzymes. Understanding:. The contraction of circular and longitudinal muscle layers of the small intestine mixes the food with enzymes and moves it along the gut. The pancreas secretes enzymes into the lumen of the small intestine. . Kaur. P.G.G.Govt. . College, Sector 11. CHANDIGARH. Intracellular . digestion. Intracellular digestion .
