What is the gallbladder and its function?
What is the gallbladder and its function?
A small sac that stores bile produced by the liver. Bile helps break down fats in the small intestine.
What does the large intestine do?
What does the large intestine do?
The large intestine absorbs water from digested food, forms solid waste, and stores it before elimination.
What is the rectum's role?
What is the rectum's role?
The rectum is the final section of the large intestine. It stores feces and signals the brain when it's time to eliminate waste.

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
