Bellwork Time!
● Work with your table on this!● List at least 5 foods that you ate for breakfast today. ● Try to list as many organs that you think helped in the digestion of
your breakfast.
![Page 3: Food and Digestion Lecture Elizabeth Kim Eugene Baeg Jihun Jeong Zenith Shrestha](https://reader036.vdocuments.site/reader036/viewer/2022062422/56649f255503460f94c3c2a0/html5/thumbnails/3.jpg)
See how many you got correct!
● The person in the middle stand up and HONESTLY say how many you got!

5 Teaching Points
● Food provides us with energy.● Helps grow and repair cells.● Our body requires 6 essential nutrients `to function.● There are many organs involved in digestion, which is when food
is broken down into usable forms of energy (ATP).● There are two types of digestive processes, mechanical and
chemical reactions.
![Page 5: Food and Digestion Lecture Elizabeth Kim Eugene Baeg Jihun Jeong Zenith Shrestha](https://reader036.vdocuments.site/reader036/viewer/2022062422/56649f255503460f94c3c2a0/html5/thumbnails/5.jpg)
● Food provides us with energy for everything● Provides materials for growing and for repairing tissues● Food contain nutrients, substances that provide energy and help
carry out essential processes like respiration, etc.
Food and its purposes
![Page 6: Food and Digestion Lecture Elizabeth Kim Eugene Baeg Jihun Jeong Zenith Shrestha](https://reader036.vdocuments.site/reader036/viewer/2022062422/56649f255503460f94c3c2a0/html5/thumbnails/6.jpg)
Carbohydrates
● Provides short term energy● Made up of carbon, oxygen and hydrogen● Make materials to make cell parts● Pasta, rice, potato, etc.
![Page 7: Food and Digestion Lecture Elizabeth Kim Eugene Baeg Jihun Jeong Zenith Shrestha](https://reader036.vdocuments.site/reader036/viewer/2022062422/56649f255503460f94c3c2a0/html5/thumbnails/7.jpg)
Fats
● 2x energy than carbohydrates (long term energy)● Makes up cell membrane● Protect/support internal organs● Insulates our body
Healthy Fats Unhealthy Fats
Unsaturated Fat Saturated Fat
Trans Fat
Cholesterol
![Page 8: Food and Digestion Lecture Elizabeth Kim Eugene Baeg Jihun Jeong Zenith Shrestha](https://reader036.vdocuments.site/reader036/viewer/2022062422/56649f255503460f94c3c2a0/html5/thumbnails/8.jpg)
Vitamins
● Can sometimes be made by our body ● Helps in chemical reactions, like blood clotting● All vitamin helps your body based on its letter (Vitamin C is food
for your skin)
![Page 9: Food and Digestion Lecture Elizabeth Kim Eugene Baeg Jihun Jeong Zenith Shrestha](https://reader036.vdocuments.site/reader036/viewer/2022062422/56649f255503460f94c3c2a0/html5/thumbnails/9.jpg)
Minerals ● Do not provide energy● Keep our body healthy (calcium provides strong bones, etc.)● Not made by living things● We get them by eating them● Absorbed by plants through roots
![Page 10: Food and Digestion Lecture Elizabeth Kim Eugene Baeg Jihun Jeong Zenith Shrestha](https://reader036.vdocuments.site/reader036/viewer/2022062422/56649f255503460f94c3c2a0/html5/thumbnails/10.jpg)
Proteins
● Meat, cheese, eggs, and dairy product● Used for tissue growth and repair● Chains of amino acid makes a big protein● Skin diseases results from lack of protein
![Page 11: Food and Digestion Lecture Elizabeth Kim Eugene Baeg Jihun Jeong Zenith Shrestha](https://reader036.vdocuments.site/reader036/viewer/2022062422/56649f255503460f94c3c2a0/html5/thumbnails/11.jpg)
Water
● Also known as H20● Allows organisms to function properly● Soften downs food and makes it easier to digest● Helps in blood circulation because its a good solvent
![Page 13: Food and Digestion Lecture Elizabeth Kim Eugene Baeg Jihun Jeong Zenith Shrestha](https://reader036.vdocuments.site/reader036/viewer/2022062422/56649f255503460f94c3c2a0/html5/thumbnails/13.jpg)
● Food is converted into energy (ATP) first through digestion and then cellular respiration
● Mechanical Digestion: food is broken down physically● Chemical Digestion: chemicals break down food
Digestion
![Page 14: Food and Digestion Lecture Elizabeth Kim Eugene Baeg Jihun Jeong Zenith Shrestha](https://reader036.vdocuments.site/reader036/viewer/2022062422/56649f255503460f94c3c2a0/html5/thumbnails/14.jpg)
Organs involved
● Mouth, salivary gland, esophagus, liver, gallbladder, stomach, small intestine, large intestine, rectum and anus
![Page 15: Food and Digestion Lecture Elizabeth Kim Eugene Baeg Jihun Jeong Zenith Shrestha](https://reader036.vdocuments.site/reader036/viewer/2022062422/56649f255503460f94c3c2a0/html5/thumbnails/15.jpg)
The mouth and the esophagus
● Saliva is an enzyme that helps in both mechanical and chemical in mouth
● Food flows into the stomach through the esophagus● Esophagus: tube containing mucus helps in flowing of food from
the mouth to the stomach (peristalsis)
![Page 16: Food and Digestion Lecture Elizabeth Kim Eugene Baeg Jihun Jeong Zenith Shrestha](https://reader036.vdocuments.site/reader036/viewer/2022062422/56649f255503460f94c3c2a0/html5/thumbnails/16.jpg)
The stomach
● Stomach stores food and more mechanical processes takes place ● Acids such as digestive juice/pepsin, hydrochloric acid, help in
chemical reactions● The liver produces bile, which helps in breaking fat particles
![Page 17: Food and Digestion Lecture Elizabeth Kim Eugene Baeg Jihun Jeong Zenith Shrestha](https://reader036.vdocuments.site/reader036/viewer/2022062422/56649f255503460f94c3c2a0/html5/thumbnails/17.jpg)
Absorption
● Nutrients are absorbed from the food● Villis in the small intestine, help in absorptions and circulation of
nutrients
![Page 18: Food and Digestion Lecture Elizabeth Kim Eugene Baeg Jihun Jeong Zenith Shrestha](https://reader036.vdocuments.site/reader036/viewer/2022062422/56649f255503460f94c3c2a0/html5/thumbnails/18.jpg)
Ending of Digestion
● Water is absorbed in the large intestine● The waste goes out of your anus and gets released
![Page 19: Food and Digestion Lecture Elizabeth Kim Eugene Baeg Jihun Jeong Zenith Shrestha](https://reader036.vdocuments.site/reader036/viewer/2022062422/56649f255503460f94c3c2a0/html5/thumbnails/19.jpg)

Arranging Processes of Digestion
Instructions
● The steps of digestion given below are WRONG.● Re-arrange them in order that we eat food in.● Raise your hand high once you are done!● The first one to get the correct answer will get a lovely prize and
will also have to perform a surprise act with it!
![Page 41: Food and Digestion Lecture Elizabeth Kim Eugene Baeg Jihun Jeong Zenith Shrestha](https://reader036.vdocuments.site/reader036/viewer/2022062422/56649f255503460f94c3c2a0/html5/thumbnails/41.jpg)
Here we GO!
● Water is absorbed in the large intestine.● The food flows into the stomach through the esophagus.● Waste products are released from †he ånus.● Both mechanical and chemical takes place in the mouth.● Nutrients are absorbed in the small intestine.● Food enters your mouth.● Acids such as digestive juice/pepsin, hydrochloric acid, help in
chemical reactions in the stomach.
