Today, we’re going to explore the amazing organs that make up our digestive system. The digestive system is like a team of organs that work together to help us break down the food we eat. This process, called digestion, turns food into nutrients that our bodies can use. Anything that our body doesn’t need is turned into waste and leaves our body as poop.
Our journey starts in the mouth. When we eat, our teeth chew the food into smaller pieces. Our tongue helps mix the food with saliva, a liquid in our mouth that makes the food soft and easy to swallow. Saliva also has special helpers called enzymes that start breaking down the food.
Next, the food travels down a tube called the esophagus, which is like a highway for food. The tongue pushes the chewed food, now called a bolus, into the esophagus. This tube carries the food from the mouth to the stomach.
Once the food reaches the stomach, it gets mixed and churned like a smoothie. The stomach is shaped like a J and uses acids and enzymes to break the food into even smaller pieces. This is where the food starts to look more like a liquid.
After the stomach, the food moves into the small intestine, which is a long, twisty tube about 6 meters long! The small intestine has three parts: the duodenum, jejunum, and ileum. Here, juices from the pancreas and liver help finish breaking down the food. The small intestine also absorbs nutrients into the blood, which our body uses for energy and growth.
Next, the leftover food that can’t be digested moves into the large intestine. This part is shorter but wider than the small intestine, about 1.5 meters long. The large intestine absorbs extra water from the waste, turning it into solid poop. This waste then moves to the rectum.
The rectum is like a storage area for poop until it’s ready to leave the body. When it’s time, the poop exits through an opening called the anus.
Let’s quickly remember the path food takes: it starts in the mouth, travels down the esophagus, gets mixed in the stomach, absorbs nutrients in the small intestine, loses extra water in the large intestine, and finally exits through the rectum and anus. Our digestive system is a fascinating journey from start to finish!
Food Journey Map: Create a map of the digestive system using craft materials like paper, markers, and string. Label each part of the digestive system: mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus. Use different colors to show the path food takes. Discuss with your classmates or family how each part helps in digestion.
Chew and Observe: Take a small piece of bread and chew it slowly for one minute. Notice how the texture and taste change as you chew. Talk about how saliva and chewing help start the digestion process. Write down your observations and share them with your class.
Digestive Detective: Keep a food diary for a day. Write down everything you eat and think about how each food travels through your digestive system. Draw a picture of your favorite meal and label which parts of the digestive system help break it down. Share your drawing and explain the process to a friend or family member.
In this video, we will learn about the organs of the digestive system. The digestive system is a group of organs that work together to carry out digestion. Digestion is the process by which food is broken down into simpler forms so that the body can absorb nutrients from it. The leftover undigested remains are removed or excreted by our system in the form of feces.
The organs of the digestive system include the mouth, esophagus, stomach, liver, small intestine, large intestine, rectum, and anus. We intake food through the mouth, where digestion begins. Food is chewed by our teeth and broken down into small pieces. The tongue helps to mix food with saliva, which contains enzymes that make food soft and easy to swallow.
The esophagus, also known as the food pipe, is a tube-like structure that carries food from the mouth to the stomach. Inside the mouth, food mixes with saliva to form a small ball-like structure called a bolus. The tongue pushes this bolus into the esophagus, from where it is carried to the stomach.
The stomach is a J-shaped pouch-like organ that acts like a mixer, further mixing and churning food to break it into tinier particles. The acids and enzymes released by the walls of the stomach partially digest the food.
The small intestine is a long tube, about 6 meters in length, and has three parts: duodenum, jejunum, and ileum. Digestive juices from the pancreas and liver are poured into the small intestine, where the final and complete digestion of food occurs. Along with digestion, the absorption of nutrients into the blood also takes place through the inner walls of the small intestine. The leftover undigested remains of food then move into the large intestine.
The large intestine is around 1.5 meters long. It is shorter in length than the small intestine but much wider. The large intestine absorbs extra water from the undigested remains and forms feces. From here, feces pass to the rectum, and from the rectum, they are excreted through the anal opening to the outside of the body.
Let’s do a quick revision: our digestive tract extends from the mouth to the anus.
