Study Notes
Human Digestive System
- The digestive system breaks down food to provide nutrients for the body
- Food provides carbohydrates, fats, proteins, vitamins and minerals to build cells
- Without these nutrients, the body cannot function properly
Organs of the Digestive System
- Mouth: Chews food and starts carbohydrate breakdown with amylase
- Pharynx/Esophagus: Swallows food and moves it via wave motions
- Stomach: Begins protein digestion, mixes food, and produces HCl to break down proteins
- Small Intestine: Completes digestion of fats, proteins, and carbohydrates, absorbs nutrients via villi
- Large Intestine: Absorbs water and creates solid waste
- Rectum: Stores waste until elimination
- Anus: Eliminates waste from the body
- Gallbladder: Produces bile salts to break down fats in the small intestine
- Salivary Glands: Produce saliva, assists in chemical digestion
- Liver: Produces bile, a substance that aids in fat digestion
- Pancreas: Produces enzymes for digestion
Specialized Cells of the Digestive System
- Villi in the small intestine increase surface area for nutrient absorption
- Increases the number of cells exposed to food and nutrients, increasing absorption of nutrients into the bloodstream
Digestive System Function
- Absorbs nutrients from food
- Breaks down food into usable components
- Diffuses nutrients into the body's bloodstream
- Works closely with the circulatory system to deliver nutrients throughout the body
Digestive System Diseases
- Inflamed Gallbladder/Gallstones: Symptoms include pain in the upper right abdomen and back, cured by removing the gallbladder
- Crohn's Disease: Symptoms include irritable bowels, pain in the joints of the body, exhaustion, fever, nausea
- Avoid certain foods or medications
