Human Digestive System
The digestive system consists of the alimentary canal and accessory organs. The alimentary canal extends from the mouth to the anus. Accessory organs that aid digestion include the salivary glands, liver, gallbladder and pancreas. Food is broken down mechanically and chemically by these organs as it moves through the digestive tract, with nutrients being absorbed in the small intestine and waste expelled from the anus.

Human digestive system
The human digestive system consists of the alimentary canal and digestive glands. The alimentary canal runs from the mouth to the anus and contains structures like the esophagus, stomach, and small and large intestines. Digestive glands include the salivary glands, liver, and pancreas. Digestion involves both mechanical and chemical breakdown of food. Enzymes and acids in saliva, gastric juice, bile, and pancreatic juice chemically break down food into small molecules that can be absorbed in the small intestine and used by the body.
Digestive system of humans
The digestive system begins with the mouth, which includes the oral cavity, tongue, jaw, and throat. Food then passes into the esophagus and enters the stomach. In the stomach, food is churned with gastric juices containing hydrochloric acid and enzymes. The partly digested food then moves into the small intestine, where it is further broken down by enzymes from the liver, pancreas, and intestinal walls. The digested food is then absorbed into the bloodstream and transported throughout the body. Undigested waste moves into the large intestine to absorb remaining water and salts before being excreted as feces through the anus.

THE HUMAN DIGESTIVE SYSTEM
The human digestive system is made up of a long digestive tract that stretches from the mouth to the anus. Food is broken down mechanically and chemically by different organs along the tract. Mechanical digestion begins in the mouth by teeth. Chemical digestion starts in the mouth by saliva and continues in the stomach by gastric juices and in the small intestine by enzymes from the pancreas, liver, and intestinal walls. Nutrients are absorbed in the small intestine and undigested waste is eliminated in the large intestine and anus. Proper digestion relies on balanced diet, chewing, drinking water, and exercise.
Digestive system powerpoint
The digestive system breaks down food and turns it into energy. Digestion begins in the mouth through chewing and the release of enzymes. Swallowed food then passes through the esophagus into the stomach, where it is stored, mixed with acids, and further broken down. The partially digested food then moves into the small intestine, where most digestion and absorption of nutrients occurs, before exiting the body through the large intestine and anus.

COT GRADE 8 - DIGESTIE SYSTEM.pptx
Here are 3 key healthful practices to maintain a healthy digestive system:
1. Eat a balanced diet with plenty of fiber. Fiber helps food move through your system smoothly. Good sources include fruits, vegetables, whole grains.
2. Stay hydrated. Drinking enough water is important for digestion. Water helps transport nutrients and waste.
3. Manage stress. High stress levels can disrupt your digestive health. Try relaxation techniques like deep breathing, yoga or meditation.
The digestive system
The digestive system breaks down food into simple substances that the body can use for energy and nutrients. It is made up of a long tube called the digestive tract that runs from the mouth, through the esophagus and stomach, and into the small and large intestines. Food is broken down through four main stages - chewing in the mouth, churning in the stomach, nutrient absorption in the small intestines, and waste removal in the large intestines. The digestive system relies on organs like the teeth, tongue, salivary glands, pancreas, liver and gallbladder to aid the digestion process.
Lesson plan in biology
The lesson plan aims to teach students about the digestive system. It includes objectives, subject matter, and procedures. The procedures involve motivating students with a puzzle activity about the digestive system. The teacher will then present and discuss the key parts and functions, including digestion and absorption in the mouth, esophagus, stomach, small intestine, large intestine, and excretion. Students will work in groups to trace the food flow and discuss the importance. They will identify organs on a chart and answer evaluation questions to assess learning. For homework, students will research digestive disorders.

Dean R Berry Digestive System
The document summarizes the key organs and processes of the digestive system. It begins with chewing and swallowing food, which then travels down the esophagus to the stomach. In the stomach, acids and enzymes break down the food into a soft material called chyme. The chyme then moves to the small intestine where nutrients are absorbed into the bloodstream over several hours. Remaining waste then passes to the large intestine where water is removed before excretion. Other organs like the liver and pancreas play important roles in digestion and detoxification. Maintaining a healthy digestive system requires a balanced diet with fiber and probiotics.

Bacteria food borne psa (1)
This document provides instructions for a student project on bacteria and food safety. Students are asked to research a specific foodborne illness caused by bacteria by addressing several key points: (1) Identify the type of bacteria that causes the disease; (2) Describe the symptoms of the disease; and (3) Discuss methods of preventing bacterial growth in food, such as through food preservation techniques like dehydration, refrigeration, or cooking. Students are also asked to describe how the disease is medically treated and the conditions created by food preservation methods that kill bacteria. The goal is for students to create a public service announcement to educate others about the disease and food safety.
Activity 38 c microbes, plants, and you
Scientists have observed cells in every living organism. This activity examines cheek cells from the inside of the mouth, plant cells from green leaves, and amoeba cells under a microscope. The cells are observed and their structures, such as the cell membrane, nucleus, cytoplasm and different organelles, are compared. Evidence is found that human bodies and plant cells contain various internal structures besides the nucleus.
Activity 36 c looking for signs of micro life
1) The document describes an activity where students look at microbes under a microscope and record their observations. They examine things like pond water to find microbes and look at their characteristics.
2) Common microbes found include bacteria, which have a cell wall, cell membrane, cytoplasm, ribosomes, and genetic material in the cytoplasm. They can be rod-shaped, spherical, or spiral.
3) Microbes are found almost everywhere on Earth and play important ecological roles as decomposers, producers, and parts of the food web.
Activity 42 c a closer look
This document is a lesson plan on cell biology that focuses on a closer look at cells. It introduces the key discoveries that cells are the basic unit of life and most organisms are made of many cells. The purpose is to learn more about cell structures and their functions. Students will read about cells, summarize the challenge question, and complete activities including a double bubble map, cell diagrams, and reflection on why membranes are important to cells.
Activity 35 c a license to learn; parts a and b
The document discusses a cell biology activity that involves using a microscope to view samples and learn about different parts of the microscope. Students will be viewing samples under the microscope and identifying different parts of the microscope based on a diagram. The activity teaches about how microscopes have helped scientific discoveries such as identifying the cause of bubonic plague.
Race ca r rubric
This document is a rubric for grading argumentative essays. It evaluates students on identifying an issue, stating a claim, citing evidence to support the claim, explaining how the evidence supports the claim, presenting a counterargument, and rebutting the counterargument. Stronger essays clearly identify the issue, state the claim, cite and explain two pieces of evidence, present a counterargument, and rebut it, while weaker essays are missing one or more of these components.
Activity 17 b gas exchange
This document summarizes a science lab activity about gas exchange. The activity involves using an indicator called BTB to test for the presence of carbon dioxide in exhaled breath. In part A, students test samples of air, sodium hydroxide solution, and their own exhaled breath to see how the BTB indicator changes color in response to carbon dioxide. In part B, students measure the number of drops of BTB needed to detect carbon dioxide levels in the exhaled breath of their classmates. The document includes the procedure, data tables to record results, analysis questions, and a reflection question about how respiratory diseases may impact breathing ability.
17 b gas exchange
This document outlines an activity to investigate gas exchange through human respiration. Students are asked to complete anticipation guides and data tables to measure the carbon dioxide levels in exhaled breath using an indicator solution. They observe that exhaled breath turns the solution color, indicating the presence of carbon dioxide. Students then measure the amount of carbon dioxide in samples from different classmates. Finally, they analyze the experiment results and compare the compositions of inhaled and exhaled air.
Activity 14 b breakdown
The document describes an activity about the human digestive system. Students will conduct an experiment to test how the size of food pieces affects the speed of chemical breakdown during digestion. They will give some students whole candy pieces and others broken up pieces, then time how long it takes each student to finish their candy. This will model how chewing food into smaller pieces increases the surface area and allows for faster chemical breakdown in the digestive system.
Activity 14 b breakdown
The document describes an activity about the human digestive system. Students will conduct an experiment to test how the size of food pieces affects the speed of chemical breakdown during digestion. They will give some students whole candy pieces and others broken up pieces, then time how long it takes each student to finish their candy. This models how chewing food into smaller pieces increases the surface area exposed to digestive acids and enzymes, speeding up breakdown.
Activity 12 b what's happening inside
The document describes an activity to teach students about the human body's organ systems. Students will:
1) Brainstorm what they know about organ systems and write questions. They will then classify organ cards into different systems like digestive and circulatory.
2) Draw an outline of the human body and label organs and their functions. They will ask each other questions about the diagrams.
3) Use clay to model organs and discuss if the sizes are accurate. They will review how organs relate to actual body structures.
Activity 1 saving fred
This document provides instructions for an activity that teaches problem solving through having students save a character named Fred using the scientific method. Students will work through various steps: forming a hypothesis to save Fred, following a procedure to test their hypothesis, recording their results, and analyzing their methods and results. The goal is to introduce students to how scientists systematically solve problems by forming and testing hypotheses in a structured process.
Activity 2 a the pellagra story
1) Dr. Goldberger studied the disease pellagra by experimenting on prisoners and orphans. He fed some prisoners and orphans diets lacking in nutrients to see if they developed pellagra.
2) Through this experiment, Dr. Goldberger found evidence that pellagra was caused by nutritional deficiencies rather than germs.
3) However, others did not believe Dr. Goldberger's conclusion because they questioned whether it was ethical to experiment on humans, and thought the evidence from prisoners and orphans was not scientifically valid.

The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
Equivariant neural networks and representation theory

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
The cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

- 1. Body Works Unit 15B: Digestion: An Absorbing Tale October 3, 2014
- 2. Activity 15B: Digestion: An Absorbing Tale October 4, 2014 Getting Started: Compare and Contrast mechanical and chemical digestion. Introduction: Read and summarize pg.B-22 in one sentence. D igestion: An Absorbing Tale Your digestive system is responsible for both mechanical and chemical breakdown. Everything you eat and drink, including medicine enters your body through this system. You can probably name a lot of the organs that food passes through, such as the esophagus, stomach, small and large intestine. There are other organs, however, like the liver and pancreas, which help your digestive system work even though food does not pass through them. What happens as food and other substances travel through your body? How does your digestive system work? 15B Challenge: Rewrite the challenge question in your own words.
- 3. Key Words: absorb/absorption, chemical breakdown, cross-section, digestive system, function, mechanical breakdown, organ, nutrients, tissue, toxins Procedure: This is a stopping to think activity. You will read a section then answer questions about the passages main idea. Results: Student Sheet 14.1 “Your Digestive System” Cross-Section Color Time and Function Analysis: Answer Analysis Questions 1-4. Reflection: Take a closer look at the villi of the small intestine. How do the villi help nutrients move into the blood quickly?
- 4. 14.1 “Your Digestive System” Complete this sheet as you read by recording the name and function of each organ in the digestive system as you read.
- 5. 1. The core is the inside of the tube is where food is held. 2. This separates food carried in the S.I. from the rest of the body. Nutrients cross this layer when they are absorbed. 3. Nutrients enter the tiny blood vessels found in this layer. 4. Layer of muscle which contracts to move digestive products along the intestine.
- 7. Color Time • Use one color and color all the parts of the digestive system the same color. • Write the major function of each organ • Answer the following questions – How does each organ help me digest food (make a list)? – How do nutrients get from the digestive system to the rest of the organs in my body?
- 8. • The digestive system breaks down food and absorbs nutrients. This occurs from the mouth to the anus. All along the way, food is broken down through both chemical and mechanical digestion.
- 9. Produce Saliva Move food to the stomach Remove toxins Breaks down and absorbs food Aids chemical breakdown Absorbs nutrients Absorbs water Holds solid waste Where solid waste exits the body.
- 10. Question 1 • What are some functions of the digestive system?
- 11. Question 2 Functions of Digestive System
- 12. Question 3 • Imagine taking a bite of a burrito. Follow the beans in the burrito through the process of digestion. Explain what types of changes take place and where each change happens.
- 13. Question 4 • Most substances are absorbed in the small intestine and not in the stomach. Aspirin is a common exception; it is absorbed in the stomach. Some alcohol is absorbed in the stomach, but most is absorbed in the intestine. – Why would you want medicines, like aspirin, to be absorbed in the stomach instead of the small intestine? – What is the effect of some alcohol being absorbed in the stomach?
