This is a comprehensive powerpoit presentation on the parts and functions of digestive system.Human digestive system, system used in the human body for the process of digestion. The human digestive system consists primarily of the digestive tract, or the series of structures and organs through which food and liquids pass during their processing into forms that can be absorbed into the bloodstream. The system also consists of the structures through which wastes pass in the process of elimination and of organs that contribute juices necessary for the digestive process.
In order to function properly, the human body requires nutrients. Some such nutrients serve as raw materials for the synthesis of cellular materials, while others help regulate chemical reactions or, upon oxidation, yield energy. Many nutrients, however, are in a form that is unsuitable for immediate use by the body; to be useful, they must undergo physical and chemical changes, which are facilitated by digestion.

Digestive system
It discuss about what is digestion, five stages of digestive system - ingestion, digestion, absorption, assimilation and egestion. it also discuss about mouth, tongue, teeth, alimentalry canal - pharanyx, oesophagus, stomach, small intestine, large intestine, liver, pancrease etc.,
Innovative lesson plan
The document describes an innovative lesson plan for a 9th standard biology class on the alimentary canal and passage of food. The lesson uses lecture, demonstration, multimedia, group discussion and evaluation to develop students' knowledge of the key facts, concepts, and processes involved in digestion as food passes through the oral cavity, esophagus, stomach, small intestine, large intestine and is eliminated through the anus. The lesson engages students through role-playing different food items on a tour of the alimentary canal over two class periods.
nutrition in man
This lesson plan covers nutrition in man and the digestive system. The objectives are for students to identify organs of the digestive system and understand the digestion process. The lesson will cover the organs and their functions, including the mouth, esophagus, stomach, small intestine, large intestine, and anus. Enzymes produced in each organ will be discussed, such as pepsin and rennin in the stomach. Food is broken down mechanically and chemically throughout the digestive system until nutrients are absorbed in the small intestine and undigested waste is eliminated in the feces through the anus.

This handout is going to help mostly the students of nutrition, midwifery and dietetics, and public health.
Unit 7 digestion
The document discusses the process of digestion. It begins with an overview of the alimentary canal and its parts, including the mouth, esophagus, stomach, small intestine, large intestine, and anus. It then covers the stages of digestion - ingestion, digestion, absorption, assimilation, and egestion. Specific topics covered include the roles and locations of enzymes in breaking down food, as well as the functions of organs like the liver, gallbladder and pancreas in digestion.
SCIENCE8-The-Digestive-System.pptx
The document describes the digestive system and its functions. The digestive system processes and absorbs nutrients from food. It has four main functions: ingestion, digestion of food, absorption of nutrients, and elimination of solid waste. It describes each organ involved and its role, such as the mouth chewing food, the esophagus transporting food to the stomach for digestion, the small intestine absorbing nutrients, and the large intestine and anus eliminating solid waste.
Digestive System
The digestive system breaks down food into small molecules that can be absorbed and used by the body. Food goes through four steps - ingestion, digestion, absorption, and elimination. Digestion involves both mechanical and chemical breakdown of food. Enzymes produced throughout the digestive system aid in chemical digestion. The major organs of the digestive system include the mouth, esophagus, stomach, small intestine, large intestine, liver, pancreas, and gallbladder.
D)digestive system
The digestive system breaks down food and absorbs nutrients. It begins with the mouth and includes the esophagus, stomach, small intestine, large intestine and anus. Accessory organs like the liver, gallbladder and pancreas produce enzymes and bile to aid in chemical digestion. Food is mechanically and chemically broken down as it passes through the digestive tract, with the small intestine absorbing most nutrients and the large intestine absorbing water before waste is excreted through the anus.

CMC refers to computer-mediated communication, which is any communication that occurs between humans through electronic devices. CMC tools are increasingly being used in education and allow for both synchronous and asynchronous communication. Synchronous communication occurs in real time through tools like video conferencing and instant messaging. Asynchronous communication does not require participants to communicate simultaneously and can occur through email or online forums. CMC opens new opportunities for interactive distance learning and makes remote learning more similar to in-person classroom experiences.

This document discusses computer mediated communication (CMC) in education. CMC refers to any human communication that occurs through two or more electronic devices. It can take place synchronously or asynchronously through various mediums like text, audio, or video. Synchronous communication allows for real-time interaction through tools like instant messaging, video conferencing, and Skype. Asynchronous communication does not require real-time interaction and includes email, discussion forums, and social media. The document examines the elements of interpersonal communication in CMC and how it plays an important role in distance learning by allowing geographically separated students to communicate and learn like they would in a classroom.
Self pollination
Self pollination involves the transfer of pollen grains from the anther of a flower to the stigma of the same flower or another flower on the same plant. Cross pollination is the transfer of pollen grains from the anther of one flower to the stigma of a different flower of the same kind on another plant. Both self and cross pollination are important for plant reproduction and the production of seeds or fruit.
Newton’s first law of motion
This PowerPoint presentation discusses Newton's First Law of Motion. It defines force as what causes objects to move, and identifies two types of forces - pushes and pulls. Forces can be balanced or unbalanced, with balanced forces resulting in no motion and unbalanced forces resulting in motion. Newton's First Law, also known as the Law of Inertia, states that an object at rest stays at rest and an object in motion stays in motion with the same speed and direction unless acted upon by an unbalanced force. The presentation provides examples of inertia and discusses how mass relates to inertia.

It discusses the characteristics of a good syllabus and explains key aspects of different syllabus types, such as how grammatical/structural and functional/notional syllabi are product-oriented and focus on language forms and functions. Process-oriented syllabi shift the focus from content to the learning process. Procedural syllabi emphasize logically arranged classroom activities. Task-based syllabi clearly state language tasks, while negotiated syllabi are developed through teacher-student negotiations.
Online assignment
A symposium is a discussion where multiple speakers present on different aspects of a central theme. Each speaker is assigned a specific aspect to focus on. The chairman coordinates the presentations to ensure all aspects are covered without repetition. A symposium differs from a panel discussion in that the audience does not typically engage in discussion. By assigning aspects to students and having them prepare presentations, a classroom can be converted into a symposium. The components of a symposium are the theme, chairman, speakers, and audience. A symposium allows for varied viewpoints to be explored thoroughly and stimulates thinking among participants. However, it risks passivity from the audience and potential repetition if speakers are not well coordinated.
Innovative lesson plan
This lesson plan is for an English class on a story by Rabindranath Tagore. The 40-minute lesson involves the teacher creating engagement with students by discussing homophones. They then give a brief introduction to the story and do a model reading. Students are asked to read sections of the story themselves while the teacher does a second model reading. Comprehension questions are asked to check understanding, and unfamiliar words are presented with flashcards. Students are divided into groups to discuss scaffolding questions about characters and events in the story. The lesson concludes by asking students to prepare a summary of the passage.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

- 4. TOPIC: DIGESTIVE SYSTEM OF MAN
- 5. INTRODUCTION • In man digestive system consist of alimentary canal and associated glands. • During digestion various chemical reactions takes place. • With the help of this reaction food particles are divided in to small particles.
- 6. Mouth • Mouth is a transverse slit like aperture. • The teeth masticate food. • Acts as a surface for enzyme action.
- 7. Salivary Gland • Secretion in saliva by salivary gland. • Saliva is a digestive enzyme. • It converts starch in to maltose.
- 8. Oesophagus • Oesophagus is a narrow mascular tube. • Food particles moves toward by peristalsis. • It leads in to stomach.
- 9. Stomach • It is a thick mascular bag. • It converts food in to paste. • It produces gastric juice and hydrochloric acid.
- 10. Pancreas • Pancreas produce pancreatic juice. • Pancreatic juice contain trypsin amylase and lipase. • Pancreatic juice helps in digestion.
- 11. Small Intestine • Small intestine produce intestinal juice. • It absorbs digestive food in to the blood. • It is a long highly coiled narrow tube.
- 12. Large Intestine • It absorb water from the blood. • It is shorter and much wider than small intestine. • It extend from ileum to the anus.
- 13. Rectum • It store undigested food btemporarily. • Pelvic colon continues in to rectum. • Rectum opens out by anus.
- 14. CONCLUSION • Man has well developed digestive system. • It starts from mouth and ends in to anus. • Various organs and glands are involved in this process.
