Why do we need to eat food? Because food contains different nutrients that give us energy to walk, talk, run, ………. etc. Levels of biological organization 1.Cell: -The human body consists of cells. -The basic (smallest) unit. 2.Tissue: A group of cells 3.Organ: A group of tissues. 4.System: A group of organs. 19 Glory International Schools National Section Science Department Grade 3- First Term Booklet 2024/2025 The digestive system Digestion process: is breaking down food into smaller parts to get energy and growth. by the help of the digestive system. The function of the digestive system: 1- Break down complicated food into simple food (small pieces). 2- Digests and absorbs food. The structure of the digestive system: 1- Mouth 2- Pharynx 3- Esophagus 4- Stomach 5- Small intestine 6- Large intestine 7- Rectum 8- Anus 20 Glory International Schools National Section Science Department Grade 3- First Term Booklet 2024/2025 Mouth -The first part of the digestive system. -Mouth contains: Teeth: They break down food into small pieces. Saliva: -It is a liquid substance in the mouth. -It makes the food soft. - Saliva starts to digest some carbohydrates. Tongue: It mixes food with saliva in the mouth and then push the food to the pharynx. 21 Glory International Schools National Section Science Department Grade 3- First Term Booklet 2024/2025 Pharynx It connects the mouth to esophagus. Esophagus It is a long tube that contract to carry the food mixed with saliva. This process is called peristalsis. It allows the food to move from throat (pharynx) to stomach. Stomach The place where the proteins is digested and broken down into semi liquid substance by gastric juice (mixture of chemicals). 22 Glory International Schools National Section Science Department Grade 3- First Term Booklet 2024/2025 Small intestine It is about 6 meters long It is between the stomach and the large intestine. Food from the stomach enters the small intestine as a semi-liquid. In the small intestine, Digestion happens by the help of liver and Pancreas (help in breaking down the food into nutrients). The walls of the small intestine have villi (Small finger-like projections) that help to absorb these nutrients. The liquefied food moves through the small intestine by contractions of muscles in a process called peristalsis. 23 Glory International Schools National Section Science Department Grade 3- First Term Booklet 2024/2025 Large intestine It is about 1 to 1.5 meters long. It absorbs the water and salt from the undigested food so they change from liquid into solid form called feces. No digestion takes place in it. Rectum and anus At the end of large intestine is the rectum, which is where the feces wait until we go to the bathroom. The feces leave our rectum through the anus. ✓ The alimentary canal is the route food takes through your body. 24 Glory International Schools National Section Science Department Grade 3- First Term Booklet 2024/2025 Notes The liver helps in the digestion of fats in the small intestine. The gall bladder helps the liver digest fat and store bile (produced by liver and helps the digestive system to break down fats). The pancreas helps the body digest fats, carbohydrates and proteins. To keep your digestive system healthy: 1. Chew the food well. 2. Do not eat fast meals. 3. Drink a large amount of water. 25 Glory International Schools National Section Science Department Grade 3- First Term Booklet 2024/2025 Dictation Digestive system – Mouth - Stomach- Small intestine – Large intestine - Rectum- Anus- Pharynx- Esophagus – Peristalsis – Liver – Pancreas – Villi – Tongue – Saliva – Alimentary canal. 26 Glory International Schools National Section Science Department Grade 3- First Term Booklet 2024/2025 Digestive The organs in your system body that process the food you eat The opening through which an animal or Mouth human take in food The soft part of the Pharynx throat connects the mouth and nose to esophagus The tube that connects your mouth through Esophagus throat to the Stomach 27 Glory International Schools National Section Science Department Grade 3- First Term Booklet 2024/2025 The organ in the body where protein is Stomach incomplete digested The narrow and long Small intestine upper of intestine, here the food is digested The shorter part of the intestine that absorbs Large intestine water and eliminates the residues of digestion 28 Glory International Schools National Section Science Department Grade 3- First Term Booklet 2024/2025 Is the last part of large Rectum intestine The opening through which solid wastes Anus leave your body.
