The document summarizes the key components and functions of the digestive system. It discusses the phases of digestion including ingestion, digestion, absorption, assimilation and ejection. It describes the mechanical and chemical digestion that takes place in the mouth, stomach, small intestine and large intestine. The accessory organs - liver, gallbladder and pancreas - play important roles in producing bile and digestive enzymes to break down food.
Digestion
Digestion may be defined as physiological process by which complex food particles are broken down into simple form which are suitable for absorption and subsequent utilization.
Digestive system
Digestive system is the system which involves organs that are responsible for the process of digestion.
Gastrointestinal Tract:
The digestive system is composed of a long muscular tube – the gastrointestinal (GI) tract, or alimentary canal – and a set of accessory organs.
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.,

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

This presentation provides a briefing on how to upload submissions and documents in Google Classroom. It was prepared as part of an orientation for new Sainik School in-service teacher trainees. As a training officer, my goal is to ensure that you are comfortable and proficient with this essential tool for managing assignments and fostering student engagement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

• Teeth mechanically
break down food into
small pieces. Tongue
mixes food with saliva
(contains amylase,
which helps break down
starch).
• Epiglottis is a flap-like
structure at the back of
the throat that closes
over the trachea
preventing food from
entering it. It is located
in the Pharynx.
8. Oesophagus(Grasnaal)
• Approximately 20 cm long.
• Functions include:
1. Secrete mucus ( Mucus
membrane)
2. Moves food from the throat to
the stomach using muscle
movement called peristalsis
• If acid from the stomach gets in
here that’s heartburn.

10. Small Intestine
• Small intestines are roughly 7 meters long
• Lining of intestine walls has finger-like
projections called villi, to increase surface
area.Duodenum,Jejunum,illium
• The villi are covered in microvilli which
further increases surface area for
absorption.

11. Small Intestine
• Nutrients from the food pass into the
bloodstream through the small
intestine walls.
• Absorbs:
– 80% ingested water
– Vitamins
– Minerals
– Carbohydrates
– Proteins
– Lipids
• Secretes digestive enzymes

12. Large Intestine
• About 1.5 meters long
• Accepts what small intestines don’t
absorb
• Rectum (short term storage which
holds feces before it is expelled).
14. Accessory Organs The Glands
• Not part of the path
of food, but play a
critical role.
• Include: Liver, gall
bladder, and
pancreas
15. Liver
• Directly affects digestion by producing
bile Juice
– Bile helps digest fat
• filters out toxins and waste including
drugs and alcohol and poisons.
• It Helps in Osmoregulation and
formation of Vitamin D

16. Gall Bladder
• Stores bile from the
liver, releases it into the
small intestine.
• Fatty diets can cause
gallstones

Great Job!
A good way to describe peristalsis is an ocean wave moving through the muscle.
These diagrams don’t separate the esophagus from the mouth functions, you might want to talk about what happens in the mouth too.
The stomach takes around 4 hours to do it’s job on the food, depending on what kinds of food are digested.
Depending on the maturity of the group, you can talk about the feces leaving via the anus.
Mention the appendix at the bottom of the ascending colon and that it might have been used long ago but is not today
Mention the portions of the large intestine, ascending, transverse, descending, sigmoid, and rectum (last one if the audience is mature enough)
Livers can regenerate missing pieces if necessary. Is one of the largest organs in the body.
Explain to students that removing the stones typically means removing the gallbladder, but that the body eventually adjusts to not having the bile stored.
Explain the difference between the two types of diabetes. In type 1, the pancreas fails to produce enough insulin. In type 2, the body stops responding properly to the insulin it creates.
