This PowerPoint presentation details out the anatomy of the human digestive system. Their are general terminologies that involves the topic but over-all this work focuses on how digestion takes place in the human body. The details coming from this presentation are combined from four different and liable sources/references including Biology (Thomson Asian Edition). I can say that this presentation is brief and well-organized so I hope this could help you in your class or seminars. Thanks.

I made this presentation for my school project after that I thought that I should upload it on any slide so I uploaded this to help others in making presentations and getting ideas.It is a class 7 project.
The digestive system is made up of the gastrointestinal tract—also called the GI tract or 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.
Digestive System of the Human Body.
Detailed explaination.
According to ICSE syllabus for grade 9.
This Presentation includes: The alimentary canal, organs and their functions, secretions, processes and definitions.
Based on selina publishers- Biology Part 1 grade 9.
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”.
How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.

2. The chemical
breakdown of complex
biological molecules
into their component
parts.
Lipids to fatty acids
Proteins to individual
amino acids
Carbohydrates into
simple sugars
4. Structures in the mouth that aids
digestion:
Teeth – cut, tear, crush and
grind food.
Salivary glands – produce and
secrete saliva into the oral
cavity.
Parotid (beneath the cheeks)
Submaxillary (below the jaw
bone)
Sublingual (below the
tongue)
– saliva moistens
the food and contains enzymes
(ptyalin or salivary amylase)
that begins digestion of starch
into smaller polysaccharides
5.

8. the tube that connects your
mouth and your stomach
A straight muscular tube that is about
10 inches (25 cm) long which
connects the mouth with the
stomach
Food takes about 4 to 8 seconds as it
passes through to the stomach.
Its walls contain smooth muscles that
contracts in wavy motion
(Peristalsis).
Peristalsis propels food and liquid
slowly down the esophagus into
the stomach.
Cardiac Sphincter (ring-like valve)
relaxes to allow food into the
stomach.
9. J-shaped muscular sac
Has inner folds (rugae) that
increases the surface area of the
stomach.
Churns and grinds together the
bolus into smaller pieces.
Food is mixed with gastric juices
(hydrochloric acid and enzymes)
secreted by the stomach walls.
HCL helps break down food and
kills bacteria that came along with
the food.
10.
11. Pepsin – major enzyme; converts proteins
into peptides in the presence of HCL.
Mucus – lubricates food and protects the
gastric lining from strong digestive juices.
Converts the bolus into a liquid (chyme)
after 4 hrs of mechanical and chemical
digestion
Chyme passes through the pyloric
sphincter into the small intestine.
12.
13. Tube that is 20 feet long.
Continues to digest food
Food stays in your small intestine for 4
to 8 hours
Has three parts:
Duodenum – upper part; about 10 in;
connected to the stomach.
– where the digestive juices
from the pancreas and the liver combine
with chyme making it thin and watery.
Jejunum – about 8 ft
Ileum – about 12 ft
14.
15. Mixing: Segmental contraction that occurs in small intestine
Secretion: Lubricate, liquefy, digest
Digestion: Mechanical and chemical
Absorption: Movement from tract into circulation or lymph
Elimination: Waste products removed from body
16. Pancreas
Produces a juice that contains
enzymes (amylase and insulin)
to break down carbohydrates,
fats and protein.
Secretes the juice into the
duodenum through the
pancreatic duct.
17. Storage tank for bile (a greenish-yellow liquid)
that helps your body break down and use fats
Located under your liver
Shaped like a pear
Stores bile in between meals
Secretes bile to the duodenum
through the bile duct during
mealtime.
Bile contains bile salts, pigments,
cholesterol and phospholipids.
Bile is an emulsifier NOT an
enzyme.
Emulsifier – dissolves fat into the
watery contents of the intestine.
18. Waste is pushed into the expanded
portion (rectum) of the large
intestine.
Solid waste stays in the rectum
until it is excreted through the
anus as feces.
Appendix hangs on the right side
of the large intestine.
Tube that is 5 feet long
Gets waste from small intestine
Waste stays for 10 to 12 hours
19.
20. Colon is part of large
intestines. The colon forms
waste material that is going
to be sent out of body.
They are of three types…
1. ascending colon
2.transverse colon
3. descending colon
The rectum and anus are part
of large intestines. They
release waste material from
the body.
