Digestion worksheets for grade 4 students cover different topics related to digestion like microbes, digestive system, and teeth.
Digestion Process
Digestion is a process that occurs inside your body. It all starts in your mouth where you chew your food into small pieces. Then, it travels down a long tube called the esophagus and into your stomach. Here, special juices help break down the food even more. Next is the small intestine, where all the good stuff gets absorbed into your body. Finally, waste travels to the large intestine before leaving your body. Then the waste is removed from the body through the anus.
Digestive System
Our digestive system has many important parts that work together to help our bodies break down food. It starts with the mouth, where we chew our food into smaller pieces. Then, the food travels down the esophagus to the stomach, where it gets mixed with digestive juices. Next, it moves into the small intestine, where nutrients are absorbed into the body. Finally, waste passes through the large intestine where water is absorbed, and waste exits the body through the anus. Each part plays a crucial role in helping us digest our food and stay healthy.
Microbes
Microbes are tiny living things that are found everywhere. Bacteria are single-celled organisms that can be helpful or harmful. Viruses are even smaller and can make us sick, like the flu. Protozoa are tiny creatures found in water, some are friendly while others can cause sickness. Fungi are like mushrooms and molds, they help decompose things but can also cause infections.
Teeth
Teeth come in different types, each with its special job. Incisors are like little knives at the front, great for biting into apples. Canines are pointy and help tear food. Molars are flat and perfect for grinding. Premolars are for grinding and chewing. Every tooth has a crown, the part you see, enamel is the hardest covering of teeth and roots anchoring it in your gums.
