Digestive System — Grade 7 Science Worksheets.The body's breathing system. The body's system of nerves. The body's food-processing system. The body's blood-transporting system. Digestion begins in the mouth. The gullet. The rectum. The small intestine. The large intestine. Our throat divides into two separate tubes: the windpipe and the gullet. What prevents food from entering the windpipe? The uvula. The tongue. The trachea. The epiglottis. Where does the partly-digested food in liquid form go after it leaves the stomach?
The appendix. The digestive system processes food into usable and unusable materials. The usable materials are sent to the body's cells as food. What happens to unusable materials? It goes into the pancreas to await disposal. It goes to the right ventricle to await disposal.
It goes into the large intestine to await disposal. It goes into the small intestine to await disposal. Solid waste leaves the body through the rectum then the anus. Liquid waste leaves the body after passing through the Digestion takes place in a long tube-like canal called the alimentary canal, or the digestive tract.
Food travels through these organs in the following order:. The liver is located in the abdomen and performs many functions. Which of the following is NOT a function of the liver? Storing food. Manufacturing insulin. Producing digestive juices. Healing itself when it is damaged.Fetch robotics competitors
Digestive System What is the digestive system? The body's breathing system The body's system of nerves The body's food-processing system The body's blood-transporting system Digestion begins in the mouth.
The tongue keeps the food in place in the mouth while the food is being chewed. The digestive juices can react more easily with the food when chewed.Crown of success ritual
The food is completely digested and is absorbed by tiny blood vessels in the walls of the stomach. It passes from the small intestine into the large intestine, then into the blood.The Digestive system is also called alimentary canal and it is supported by organs like teeth, tongue, liver, and others. The digestive system helps to convert food into energy and nutrients to nourish the body.
The food we take in is thoroughly digested and absorbed by our body and the wastes are eliminated through the excretory system. The food particles get digested in every stage of the alimentary canal as they move. The mouth has many accessory organs such as the tongue, teeth, and salivary glands, which help in the digestion of food. Food is grinded by the teeth. This moistens the food, and break the food down into usable and absorbable components and then the food is pushed down into the pharynx.
The pharynx acts as a passage for the chewed food from the mouth to the esophagus. It has a flap of tissue known as the epiglottis preventing the food from getting into the wind pipe and helps us from getting choked while we eat. The esophagus is a tube joining the pharynx to the stomach.
It is made of flexible muscle to help pushing of food easily. It carries swallowed food down its long tube and pushes it to the stomach. The stomach is a thick-wall made of muscle in the form of a bag that is located on the left side of the abdominal cavity.
It is the largest part of our digestive system. Stomach acts as a storage place for food. And slowly digests food. It gets food from the food pipe and sends it to the small intestine. The stomach has digestive acids which help reduce food into further absorbable substances. Mucous protects the inner walls of the stomach. This can otherwise get damaged while digesting food.Eset phone
Because the acid reacts with the bacteria and kills it that enters our body with food. The digestive enzymes break down proteins into simpler substances. The small intestine is just named small. But it is the longest part our digestive system. The length of the small intestine depends on the diet of the organism. A major proportion of digestion takes place in the small intestines. Nutrients get digested here. The walls of the small intestine also secrete juices for digesting food.
The enzymes in the intestine convert the carbohydrates into glucose, proteins to amino acids and fats into fatty acids and glycerol. The liver releases bile. This neutralizes the acidity level of the food. Once the food is broken down into the simple particles, it is ready to be absorbed by the body. The absorbed food is then carried to different parts of the body through the blood vessels for cell activities.
The large intestine is a thicker tube than the small intestine. The large intestine absorbs water and left over nutrients from the remaining food with the help of many bacteria in it.As students enter the room, they take out their journals and respond to the prompt: What is the function of the digestive system?
Prior to this class, the students took notes on this topic, so I expect them to be able to provide a brief, accurate description. While the students write, I circulate through the room to review their responses. During this time, I may ask them to elaborate on an idea, or further explain information.
This is especially helpful in determining each student's level of understanding. This practice is also helpful in determining which portions of the information to emphasize and further explain as we review the notes. For example, if very few students are using the terms chemical or mechanical digestion, I make sure that I review and explain the terms during the next portion of the lesson. Finally, checking in with the students helps them feel more comfortable with their answers, making them much more willing to share their journals with the class later.
I then ask for volunteers to share their journals with the class, advancing the slides as necessary to review the information shared by the students. I also ask the rest of the class to provide additional examples or information based on the comments of their peers. In this manner, we are able to review the notes without me standing in front of the class and reading the notes to them. In order to ensure that all of the information is accurately and adequately covered, I ask the students questions.
For instance, tying back to the journal example of chemical and mechanical digestion, I ask the students to explain the two types of digestion in addition to explaining how and where they occur.April taurus vs may taurus
I also spend time discussing how the digestive system impacts and is impacted by other body systems, such as the circulatory system. This review of the notes addresses NGSS MS-LS The body is a system of interacting subsystems as we discuss the structures of the digestive system and the ways in which the digestive system interacts with other body systems, as is listed as a question on the student notes review.
I open each of the websites that the students will be using for the activity and explain how each of the websites functions as we review the worksheet directions as a class.
I emphasize to students that the primary objective of the day's activities is to explore various models of the digestive system and then to critically examine the models in light of what we know about the digestive system to determine the accuracy of the models. The Cross Cutting Concept of Systems and System Models - Models are limited in that they only represent certain aspects of the system in study - is addressed as the students critically examine the models they use.
Furthermore, the Cross Cutting Concept of Structure and Function - Complex structures and systems can be modeled to describe how function depends on the relationship between various parts - is addressed as the students use the models and see how food passes through each of the structures of the digestive system.Digestive System - video for kids
In the first activity, A Journey Through the Digestive Systemthe students take the form of a sandwich as they travel through the digestive system to meet various objectives on each level. I remind the students that for this activity I want them to specifically explore how the interactive matches what they know about the digestive system. This can be a difficult game, so I do not require the students to complete all of the levels, but the more levels they complete, the better able they will be to answer the questions.This Science quiz is called 'Basic Anatomy - The Digestive System' and it has been written by teachers to help you if you are studying the subject at middle school.

Our bodies do so many things that we take for granted such as how our hearts pump and keep blood circulating throughout the body or how the brain has to send out signals throughout the body in order for any part of the body to work.
Then there is food. The food breakdown goes through a long process known as the digestive system. The digestive system involves several different organs and glands.
Human Digestive System (2) – Grade 7 Science Worksheets
In simple terms, the digestive system is a long, twisting tube that runs from the mouth to the anus. This tube passes through other organs such as the stomach, the liver, the pancreas and the intestines.
The digestive process actually begins at the mouth where food and liquids are consumed. Chewing begins the process of breaking down the food into smaller particles. In addition, fluid in your mouth called salivawhich is produced by the salivary glandscontains an enzyme that begins to break down the starches in food into smaller molecules.
Enzymes are proteins that speed up chemicals actions in the body to break down food.
After food is chewed it passes on to the esophagus. This is where the tube runs from the mouth to the stomach. The esophagus uses muscle movements, almost like a wave movement, to move the food down to the stomach.
From the esophagus the food enters into the stomach which is an organ much like an empty sack. In the stomach the food is churned around for 1 to 2 hours where it is further broken down by gastric acid. The food that is mixed with gastric acid is now called chyme. After being broken down in the stomach, the chyme then begins its journey through the intestines.
The small intestine comes first and eventually the chyme makes its way into the larger intestine. The first part of the small intestine is called the duodenum while the middle part of the small intestine is called the jejunum. Finally the chyme passes through the ileum which is the last section of the small intestine. While passing through the small intestine, bile is produced in the liver and then it is stored in the gall bladder. Next, pancreatic enzymes from the pancreas, as well as other digestive enzymes that are produced in the lining of the small intestine continue to break chyme food down even further.
Finishing its journey through the small intestine, the broken down food now passes to the large intestine. The large intestine contains many different microbes. Microbes are bacteria that further help to break down food particles.
While passing through the large intestine, water and electrolyte various chemicals that include sodium are removed from the food. Like the small intestine, the large intestine also contains several different parts. The first part is called the cecum. The appendix is connected to the cecum but the appendix does not take part in the digestive process. The next part of the large intestine is known as the ascending colon.For the students of 7th grade, the subject of science is equally important as any other subject matter.
Science is a major contributor to the development of human civilization. We have science around us, we are eating, breathing, running, Behind these actions, the principles of science are working somewhere. Modern human society is completely different from the ancient times of human society!
The revolutionary changes are seen in his lifestyle, clothing and circumstances. The conversion of this transformation or change of this change goes to science itself.
If we call the modern era of science the era of science, it will never be exaggerated, but the above statement will be absolutely appropriate considering the present environment.
With the help of science, the importance of time and distance has diminished today. Today, a man sitting thousands of miles can talk to his friends and relatives in such a way as to be sitting in front. Such fast-moving aircraft and air buses. Train, motor, tram, ship, scooter etc. Teleprinter, telephone, television have proved to be a great tool for humans.
With the help of science, news can be delivered from one place to another at an early location at a quick time. Qus: In a food chain, which are the most efficient users of solar energy? Carnivores B. Herbivores C.

Qus: Where would rainy, unsettled weather most likely form? In the middle of a warm air mass B. At a front, where two air masses meet C. In the middle of a cold air mass D.Speak now. Much like many of the processes our bodies undertake in the background, we can easily take our digestive systems for granted the second the food disappears down our throats and the manual part is over.
