Organs of the Digestive System and their Functions • The body takes energy from the food taken and digested. • Digestion of food is carried out by the organs and substances of the digestive system. During digestion, food is broken down into smaller parts, a fraction of which is made up of nutrients. • The digestive system is made up of the gastrointestinal tract also called the GI tract or digestive tract. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system. • Humans and almost all animals have a digestive system in which food enters the mouth, which moved through a long tube, and exits the anus as feces. The food is broken down into soluble molecules and is moved rhythmically by the smooth muscle in the walls of the digestive system. • The digestive process is a system and if one part of the system is not working properly food will not be properly digested.

Teacher says: Yesterday, July 6 was the kick-off for this year’s 2023 Nutrition Month Celebration Nutrition Month Celebration with the theme, Poster “Healthy Diet Gawing Affordable for All!” This year's nutrition month campaign calls for unity and strengthened food and nutrition security policies and programs that will enable us Filipinos to have greater access to healthy, safe, and affordable food. Teacher asks: Speaking of health and nutrition, did you eat breakfast before coming to school today? Have you ever wondered what happened to the food you ate? Motive Question: What do you think is the organ system involved in the digestion of your food? ELICIT (Spring-Board Activity) Reading Time Teacher asks: What are healthy foods? Teacher tells: I have here a short article titled “What are healthy foods?”. Listen carefully as I read it to you. Then, later on, I will give you time to read it yourself. (Learners read the article after the first reading from the teacher.) Teacher asks: What is the article about? Based on the article, what are healthy foods? How do healthy foods help our bodies? Why do we need to eat fruits and vegetables? What do you think happens to the food you eat? ENGAGE (Scaffolding- Get the learners’ minds focused on the topic) Teacher shows the Human Torso Model containing the organs of the digestive system. Then, the teacher shows pictures of the different parts and organs of the body and lets the learners identify and name each of the body parts and human organs. Brgy.

Model based on the term flashed on the screen. EXPLORE (Presenting examples/ instances that provide learners with common experience) ACTIVITY: CRACKER IN THE MOUTH Teacher gives each learner a piece of bread pan/ breadstick/ cracker Bread pan/ breadstick/ cracker/ and tells them to take a bite. Ask them not to chew the cracker; just biscuit hold it in their mouth for 10 seconds. Then, chew later if it’s difficult to swallow still. 10 seconds Timer Ask the following questions: 1. What happened to the cracker when it’s inside your mouth? 2. What does it feel like initially? What did you taste? 3. What does it feel after 10 seconds in your mouth? 4. Why did it start to get softer? What it feels like when you chew it? 5. Have you experienced difficulty in swallowing your food without chewing it properly? 6. Why do you think Digestive System is important? Teacher says: All the systems in the body need energy to work. It is important that the body gets all the nutrients it needs to function well. They get this energy from food. However, the body cannot use food in the form in which it enters the body. So, it has to be broken down and changed into liquid form. This is in the process of digestion. The organs of the digestive system work together to accomplish this process. Brgy.

Teacher says: The digestive system is a continuous pathway. It is the system of organs responsible for getting food into and out of the body and for making use of food to keep the body healthy. It is divided into two parts: the organ of the alimentary tract that comes in contact with the food and the accessory organ that pour out secretion to assess the digestive system. Teacher says: Let us take a journey throughout the human digestive system to see how it works and how the organs coordinate in order to carry out the processes of digestion. The mouth, esophagus, stomach, small intestine, large intestine, rectum and anus from the pathway are called the digestive tract. Teacher says: Digestion of food begins in the mouth as the teeth grind up and turns food into small pieces with the help of the saliva. Our activity in eating the cracker shows how the saliva in our mouth lubricates and softens the food we ate. The mouth contains the teeth which break down the food into smaller pieces. The tongue is a muscular organ that mixes food with saliva and aids in swallowing food. The duct of the salivary glands secretes saliva that lubricate the food and the palate that forms the roofing of the mouth. The Esophagus receives food from the mouth and carries food into the stomach. Epiglottis is a small flap that folds over our windpipe as we swallow to prevent us from choking. During swallowing, the bolus is conveyed by the esophagus into the stomach via wavelike contraction and relaxation of involuntary muscle which is called peristalsis. Bolus is a small rounded mass of chewed food at the moment of swallowing. The stomach is a muscular sac that actually churns, mashes, mixes food, and adds special chemicals, or gastric juices to the bolus. The stomach is a pear-shaped organ that is about 30.5 cm long and 15.2 wide, the bolus that enters the stomach will convert to semi-fluid partially digested food called Chyme. The Chyme enters the small intestines. Small intestine is considered as the organ of complete digestion and absorption, it is considered as the longest organ of the digestive system. Food does not pass through the liver, gall bladder and pancreas. They are accessory organs of the digestive system. The small intestine signals the pancreas to produce pancreatic juice, and the gall bladder to release bile. Pancreatic juices aid in the digestion of protein and carbohydrates and the bile is responsible to break down fats. Liver produces bile, breaks down fat, and removes toxins. Gall bladder stores the bile that the liver produces. Pancreas produces enzymes that help break down foods. The small intestines digest and absorb proteins, fats and carbohydrates. While the large intestines absorb salt and water from food. It stores the fecal materials, absorbs the Brgy.

Large intestine connects the small intestines to the rectum. Stool or waste left over from the digestive process is passed through the colon by means of peristalsis. The stool or undigested residue or the feces will be stored in the Rectum and then excrete to the Anus. Teacher asks: In summary, what are the organs that composed the digestive tract? MES-SI-LI-RAn (Mouth, Esophagus, Stomach, Small Intestine, Large Intestine, Rectum and Anus) What are the accessory organs in the digestive system? LPG-SG (Liver, Pancreas, Salivary Glands) What are the functions of the organs of the digestive system? (They are responsible for breakdown and absorption of nutrients from food by bringing energy to the body.) Gallbladder, Trivia: BORBORYGMUS is the rumbling sound in the stomach. BORBORYGMUS on the screen When you hear your stomach rumbling, it is a signal from your brain that the stomach has begun digestion. Teacher says: The journey of the food starts from the mouth down to the anus and takes about 18-20 hours. ELABORATE (Guided Practice) Teacher says: Let us watch the short video clip from YouTube to further visualize the digestive system from a different perspective. https://youtu.be/Og5xAdC8EUI How your digestive system works - Emma Bryce GENERALIZATION: What are the different organs of the digestive system? How do these organs work in the digestion of foods? What do you think will happen if one part is not well-functioning? ENRICH (Developing Mastery-Differentiated Instructions and Activities) Teacher says: Before we proceed, I would like you to have a short work break to refreshen your mind and muscles. Break Time energizer Teacher says: This time, I will divide you into four groups according to your interest and each group will have their respective work. Group 1 – the learners will label the parts and give the functions of each part of the digestive system using a diagram and literature. Group 1: Group 2 – the learners will identify each picture card of the organs Group 2: and parts of the human digestive system and give their functions with the help of literature. Brgy.
