You are to write a Eulogy for their Maniken that FILLS the space provided.
A Eulogy is a well-crafted speech about the
Maniken’s life. Use your imagination and put some effort into
it! Things they may include is a life sketch, funny stories, accomplishments, etc.
This will be due at the end of the Digestive Unit!

After the video you will be using what you learned and pages 664-667 (and glossary) in your text to answer the following questions:
1. List and define the following general functions of the digestive system: digestion, ingestion, propulsion, absorption, and defecation/excretion.
2. Explain the difference between mechanical and chemical digestion. Give an analogy for each type that you might see in your everyday activities.
3. Explain the difference(s) in function between the structures of the alimentary canal and the accessory organs of the digestive system.

Digestion – mechanical and chemical breakdown of foods into forms that cell membranes can absorb.
Ingestion – Taking food into the body by way of the mouth.
Propulsion – movement of food (peristalsis) through the alimentary canal.
Absorption – the taking of substances by cells across membranes.
Defecation/Excretion – discharge of feces from the rectum; elimination of metabolic wastes such as urine.

Mechanical Digestion – breaking large pieces of food into smaller ones, without changing their chemical composition.
Chemical Digestion – breaks food into simpler chemicals – using chemicals.
Alimentary canal structures are what the food moves through from mouth to anus, and accessory structures are those that provide chemicals to help break down and absorb the food.
![Page 8: Physics SP Skills Unit - Wikispacesbradyfonnesbeck.wikispaces.com/file/view/MaP+Unit+10+Digestive... · This will be due at the end of the Digestive Unit! ... structures of the alimentary](https://reader034.vdocuments.us/reader034/viewer/2022051601/5ada669f7f8b9ae1768d1ac1/html5/thumbnails/8.jpg)
Cracker Example! No mechanical digestion please!
Add to your notes please:
Your saliva has an enzyme called salivary amylase in it. Which type of macromolecule does it break down?
It begins the breakdown of carbohydrates, specifically starch into a smaller carb called maltose.
![Page 9: Physics SP Skills Unit - Wikispacesbradyfonnesbeck.wikispaces.com/file/view/MaP+Unit+10+Digestive... · This will be due at the end of the Digestive Unit! ... structures of the alimentary](https://reader034.vdocuments.us/reader034/viewer/2022051601/5ada669f7f8b9ae1768d1ac1/html5/thumbnails/9.jpg)
This game will review the organs of the digestive system and their functions. You will be given a few minutes to study figure 17.1 in your text before we play!
(Game is based on Ms. May’s post-it game
that we played to learn the Pathway of Breathing in the Respiratory Unit).

10 Act Gastric Juice, Pancreatic Juice, and Bile 3/30
•Made up of three basic components: pepsin, hydrochloric acid, and Mucus
Gastric Juice
Pepsin •Enzyme that facilitates the chemical digestion of proteins.
Hydrochloric Acid (HCl)
•Strong acid; provides environment for pepsin to work properly.

•Greenish fluid produced by the liver.
•Stored in the gall bladder.
•Released into the small intestine when stimulated by the presence of fat.
•Bile breaks fat into smaller pieces mechanically. This is called EMULSIFICATION.
•Other enzymes called LIPASES break fat down chemically.
Bile

Procedure:
1. Take a plastic plate.
2. Pour milk to cover the bottom of the plate and then some (The milk will represent fat in the intestine).
3. Add 4 different drops of food coloring to the middle of the milk (food coloring is used as an indicator).
4. Take a cotton swab and dip it into the dish soap (represents bile).
5. Dip cotton swab into the middle of the four colors or one color at a time (represents bile coming in contact with fat).
6. Observe!
Answer in your lab book:
Explain, in 3 or more complete sentences, why this is a good demonstration for how bile emulsifies fat.

Maceration – muscular waves in the stomach which mix food with gastric juice to form a liquid paste called chyme.
Segmentation – Short, small mixing movements of the alimentary canal. Rate of about 12 - 16 contractions/minute
Sloshing of chyme back and forth within the intestinal lumen

Complex series of chemical events that results in the breakdown of carbohydrates, fats, and proteins
Result of the collective effort of pancreatic juice, bile, and intestinal juice which contain digestive enzymes
Results in absorption - passage of digested nutrients into the blood or lymph

90% of absorption takes place within the small intestine
Remaining 10% occurs in the stomach and large intestine
Absorption of nutrients occurs through the villi by means of:
diffusion - facilitated diffusion
osmosis - active transport

Last stage of digestion
Due to bacterial action in the large intestine
Bacteria ferment any remaining carbohydrates and release hydrogen, carbon dioxide, and methane gas
Also converts any remaining proteins into amino acids
Absorbs any remaining water and electrolytes

By the time chyme has remained in the large intestine for 3 - 10 hours it has become a solid or semi-solid and is known as feces
Consists of water, inorganic salts, sloughed off epithelial cells, products from bacterial decomposition, and indigestible parts of food

A body mass index over 30 is an indicator of obesity.
1. Divide your weight in lbs by 2.2. This gives
you your weight in kilograms (kg). 2. Multiply your height in inches by .0254.
This gives you your height in meters (m). 3. Body mass index is calculated by: kg/m2

Oblong gland that lies posterior to the greater curvature of the stomach
Connected by ducts to the duodenum Two main types of Pancreatic Cells:

▪ Glucagon (raises blood sugar)
Acini Cells (99%)

Why does alcohol affect the CNS?
Some drugs mimic or block the molecules involved in communication between cells and therefore affect operations of the brain and body.

The rate at which alcohol enters the bloodstream is dependent on the amount of alcohol consumed, the concentration of alcohol in the beverage, the type of drink, how quickly it was consumed, body weight of person consuming it, and whether the stomach is full or empty.

a. Needs no digestion; alcohol will just absorb into the bloodstream through the stomach lining.
