Study Notes
Digestive System Functions
- The epiglottis separates the trachea from the esophagus during swallowing, preventing food from entering the lungs.
Liver and Bile Production
- The liver produces bile to emulsify fats, facilitating fat digestion and absorption.
Small Intestine Functions
- Villi in the small intestine increase the surface area for nutrient absorption, ensuring efficient uptake of nutrients.
Carbohydrate Breakdown
- Salivary amylase initiates the breakdown of carbohydrates in the digestive system, converting starches into simpler sugars.
Digestive System Structures
- Peristalsis is the rhythmic muscle contractions that move food through the digestive tract, facilitating the movement of food from the esophagus to the stomach.
Large Intestine Functions
- The colon absorbs water and electrolytes from undigested food, helping to maintain proper hydration and electrolyte balance.
Bile Storage and Release
- The gallbladder stores and releases bile into the small intestine, aiding fat digestion and absorption.
Esophagus Functions
- The esophagus uses peristalsis to transport food to the stomach, facilitating the movement of food from the mouth to the stomach.
Waste Elimination
- The rectum stores indigestible waste before elimination, serving as a temporary storage site for feces.
Vitamin Synthesis
- Bacterial flora in the large intestine play a role in synthesizing certain vitamins, such as vitamin K and biotin, which are essential for various bodily functions.
