Digestive system function:
Mechanical digestion:
Chemical digestion:
1. Mouth - Food is mechanically digested by the teeth, chemically digested by saliva
2. Esophagus - Food is pushed toward the stomach by peristalsis waves
3. Stomach - Food is mechanically digested by churning, chemically digested by acid
4. Small intestine - Nutrients are absorbed into the body
5. Large intestine - Water is absorbed into the body
6. Rectum - Feces is stored
Liver - Secretes bile into the small intestine to help digest fats
7. Anus - Feces exits the body
1. Mouth - Food is mechanically digested by the teeth, chemically digested by saliva
2. Esophagus - Food is pushed toward the stomach by peristalsis waves
3. Stomach - Food is mechanically digested by churning, chemically digested by acid
Fun facts!
The stomach is covered in a thick layer of mucus, so that the acid doesn’t destroy the stomach lining.
Stomach acid kills bacteria and pathogens, keeping you healthy even if you eat slightly rotten food.
4. Small intestine - Nutrients are absorbed into the body
5. Large intestine - Water is absorbed into the body
Fun facts!
The intestines are named for their diameter, not length. The small intestine is more than 4x longer that the large intestine! (22 ft to 5 ft)
A lot of the digestion in the intestines is done by bacteria. The colonies of bacteria that live in your intestines are necessary for processing many of the vitamins and minerals that you need to survive!
6. Rectum - Feces is stored
7. Anus - Feces exits the body
Fun facts!
Feces is the semi-solid waste (poop) that is left over from digestion. It is:
Feces is brown because of broken down blood cells from the kidneys.
Liver - Secretes bile into the small intestine to help digest fats
Other accessory organs:
Gallbladder: stores and concentrates bile before releasing it into the small intestine.
Pancreas: releases enzymes to digest fats, proteins, and carbohydrates
Appendix: unknown! Maybe stores good bacteria?

Respiratory and Circulatory Systems

Respiratory system function:
Respiratory system function: To move oxygen into the body and remove carbon dioxide from the body.
Nose - warms and cleans air
Trachea - carries air to the lungs
Bronchi - branches at the end of the trachea that lead to lungs
Alveoli - small air sacs where oxygen diffuses into the blood and carbon dioxide diffuses out
Lung - main organ of the respiratory system
Diaphragm - muscle that inflates and deflates the lungs
Nose warms air and nose hairs trap dust and particles - preventing it from entering your lungs.
The trachea and esophagus are right next to each other - the epiglottis covers the trachea when you swallow to prevent food going “down the wrong pipe.”
When the lungs inflate, oxygen diffuses into the bloodstream at the alveoli capillaries (tiny blood vessels). Carbon dioxide diffuses out and is exhaled.
When the diaphragm contracts and moves DOWN, the lungs inflate and air flows in.
When the diaphragm relaxes and moves UP, the lungs deflate and air flows out.

Cystic fibrosis
Summary
A genetic mutation leads the body to produce thicker and stickier mucus than normal in the lungs. The mucus coats the surface of the alveoli and is difficult to remove.
What’s happening in the body?
When alveoli are coated in mucus, oxygen cannot move from the lungs to the bloodstream. Less oxygen will be in the bloodstream and less oxygen will be delivered to cells.
Symptoms?
Treatment?
Sickle Cell Anemia
Summary
A genetic mutation causes mis-happen hemoglobin molecules. This leads to red blood cells that are crescent (sickle) shaped instead of circular. The crescent shaped don’t move through capillaries as easily and sometimes get stuck.
What’s happening in the body?
The crescent shaped cells do not deliver blood to body cells as easily when they can’t move through the capillaries. Body cells may not get enough oxygen. Blood clots may also form when the cells get stuck.
Symptoms?
Treatment?
Atherosclerosis
Summary
Years of high blood pressure, poor diet, or smoking lead to the buildup of plaque in arteries. The arteries get stiffer and narrower.
What’s happening in the body?
Narrower arteries allow less blood to flow through, which means that body cells get less oxygen and nutrients. Stiff arteries are more likely to break or rupture.
Symptoms?
Treatment?
Chronic Obstructive Pulmonary Disease (COPD)
Summary
Years of smoking or exposure lead to inflammation and narrowing of the trachea and damage to the alveoli.
What’s happening in the body?
When the trachea is narrower and the alveoli are damaged, oxygen cannot move from the lungs to the bloodstream. Less oxygen will be in the bloodstream and less oxygen will be delivered to cells.
Symptoms?
Treatment?
