Here are the key functions of the pancreas in digestion:
- Produces pancreatic juices containing enzymes that help break down food:
- Pancreatic lipase breaks down fats
- Pancreatic amylase breaks down carbohydrates
- Proteases break down proteins
- Releases pancreatic juices into the small intestine through the pancreatic duct
- The enzymes help further break down what the stomach has partially digested, preparing nutrients for absorption in the small intestine
- Also produces hormones like insulin and glucagon that help regulate blood sugar levels
So in summary, the pancreas plays an important role in both the digestive and endocrine systems by producing enzymes and hormones that aid digestion and metabolism. Its enzymes

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

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.

2. What is the digestive
system?
The digestive system is made up of the
gastrointestinal (GI) tract—also called the digestive
tract—and the liver, pancreas, and gallbladder. The
GI tract is a series of hollow organs joined in a long,
twisting tube from the mouth to the anus. The
hollow organs that make up the GI tract are the
mouth, esophagus, stomach, small intestine, large
intestine—which includes the rectum—and anus.
Food enters the mouth and passes to the anus
through the hollow organs of the GI tract. The liver,
pancreas, and gallbladder are the solid organs of the
digestive system. The digestive system helps the
body digest food.
3.
4. Digestion
Endogenic Exogenic
Human usually get the nutrients
they need from outside
Human use organic nutrients in his
cells to ensure the normal
functioning of the organs and
tissues contained in them.
5. Types of digestive system
• Autolysis is the enzymatic digestion of cells by the action of its own enzymes, and it mostly occurs in dying
or dead cells. It has previously been suggested that prolonged procedure time could lead to autolytic changes
from the periphery of the endoscopic submucosal dissection specimens.
Autolytic digestion
• The bacteria also produce vitamins and help protect the body from diseases. The whole population of
bacteria in our bodies is called the human microbiota.
• The relationship between you and your gut bacteria is symbiotic. This means that both you and the bacteria
benefit. Your bacteria receive a safe home and plenty to eat, and in return they help you break down food to
get the nutrients that you need to survive and grow.
• Symbiosis between microbes and their mammalian host is vital to maintaining homeostasis. Symbiotic
microbes within the gastrointestinal tract provide an array of benefits to the host, including promotion of
host immunity.

The Digestive Tract
Six Functions of the Digestive System
7. The Digestive Tract
• Ingestion
– Occurs when materials enter digestive
tract via the
mouth
• Mechanical Processing
– Crushing and shearing
– Makes materials easier to propel along
digestive
tract
• Digestion
– The chemical breakdown of food into
small organic
fragments for absorption by digestive
epithelium
The Digestive Tract
• Secretion
– Is the release of water, acids, enzymes, buffers, and
salts
– By epithelium of digestive tract
– By glandular organs
• Absorption
– Movement of organic substrates, electrolytes,
vitamins, and water
–Across digestive epithelium tissue
–Into the interstitial fluid of digestive tract
• Excretion
– Removal of waste products from body fluids
– Process called defecation removes feces
8. • The oral cavity, or mouth, is the point of entry of food into the
digestive system. The food is broken into smaller particles by mastication,
the chewing action of the teeth. All mammals have teeth and can chew
their food.
9.
10. The Oral Cavity Functions to
Provide
• sensory analysis of food material
before swallowing
• mechanical processing via the action
of the teeth, tongue, and palatal
surfaces
• lubrication by mixing food material
with mucus and salivary gland
secretion
• limited digestion of carbohydrates
and lipids
13. Saliva secreted by salivary glands aids the mechanical and chemical process of digestion.
Saliva is about 99% water and not only moistens food but cleanses the mouth, dissolves food
chemicals so they can be tasted, and contains enzymes that start the chemical breakdown of
starchy foods.
There are three pairs of salivary glands: parotid, sublingual, and submandibular (also called the
submaxillary gland).
Function of the saliva
1.Chemical digestion: breaks down starch by the function of “salivary amylase”
2.Helps chewing and swallowing
3.Lubricating effect: moisturizes the inside of the mouth and creates smoother speech
4.Solvent effect: dissolves food and allows the tongue to taste food
5.Cleaning effect: washes away food debris and bacteria remaining in the mouth
6.Antibacterial effect: Lysozyme, peroxidase and lactoferrin fight against pathogenic microorganisms
7.pH buffering effect: Prevents sudden changes in pH
8.Supplies minerals, including calcium and phosphorus, to teeth
14. • What are the three major salivary glands?
• You have three major pairs of salivary glands,
including your:
• Sublingual glands: These are below either side of
your tongue, under the floor of your mouth.
• Submandibular glands: Located below your jaw,
your submandibular salivary glands consist of two parts:
the superficial lobe and the deep lobe. Like your
sublingual glands, the saliva produced in your
submandibular glands enter your mouth from under your
tongue.
• Parotid glands: Your parotid glands are just in front
of your ears. Similar to your submandibular glands, your
parotid glands have two parts: superficial and deep. The
saliva produced by your parotid glands enters your
mouth from small ducts near your upper molars.
What is the role of salivary glands?
The main salivary gland function is saliva
production. Saliva plays an important role in
supporting your oral and overall health. For example,
saliva:
•Keeps your mouth and throat lubricated and
comfortable.
•Moistens food so it’s easier to swallow.
•Contains an enzyme called amylase, which helps
your stomach break down starches in food.
•Keeps your mouth clean.
•Helps reduce your risk of cavities and gum disease.
•Helps maintain the pH balance in your mouth.

19. Your stomach is a muscular organ that digests food. It
is part of your gastrointestinal (GI) tract. When your
stomach receives food, it contracts and produces acids
and enzymes that break down food. When your stomach
has broken down food, it passes it to your small intestine.
Stomach digestion
30. Small intestine
digestion
The small intestine is a tubular structure
within the abdominal cavity that carries
the food in continuation with the
stomach up to the colon from where the
large intestine carries it to the rectum
and out of the body via the anus. The
main function of this organ is to aid in
digestion.
As a person grows the small intestine
increases 20 times in length from about
200 cm in a newborn to almost 6 m in
an adult. The length of the small
intestine is approximated by three times
the length of the infant, or height of the
child or adult.

36. The Brunner glands, which empty into the
intestinal glands, secrete an alkaline fluid
composed of mucin, which exerts a
physiologic anti- acid function by coating the
duodenal epithelium, therefore protecting it
from the acid chyme of the stomach.
Lieberkühn glands, occupying the mucous
membrane, secrete digestive enzymes,
provide outlet ports for Brunner glands,
and produce cells that replace surface-
membrane cells shed from the tips of villi.
37. During digestion, your pancreas makes pancreatic juices called
enzymes. These enzymes break down sugars, fats, and starches.
Your pancreas also helps your digestive system by making
hormones.
