Study Notes
Digestive System Function Questions
- Saliva's Role: Saliva softens and moistens food for easier swallowing and proper digestion, not absorbing nutrients.
- Saliva Enzyme: Amylase is the enzyme present in saliva.
- Esophageal Muscle: Skeletal muscle moves food down the esophagus.
- Stomach's Function: The stomach breaks down food with acid and enzymes.
- Stomach Acid: Stomach acid helps break down food into liquid form; it does not absorb fats, neutralize toxins, or store vitamins.
- Small Intestine Parts: The small intestine has three parts: duodenum, jejunum, and ileum.
- Duodenum's Function: The duodenum receives food from the stomach and begins the process of breaking down sugars.
- Nutrient Absorption: The jejunum absorbs most nutrients.
- Large Intestine Connection: The ileum connects to the large intestine.
- Large Intestine Function: The large intestine absorbs water and electrolytes.
- Rectum Function: The rectum signals the brain about feces.
- Bile Production: The liver produces bile.
- Bile's Role: Bile helps digest fats.
Additional Digestive System Questions
- Small Intestine Length: The small intestine is about seven meters long.
- Fat Digestion: When you eat fatty foods, the gallbladder releases bile into the small intestine to aid in digestion.
- Esophageal Muscles: Esophageal skeletal muscles are important for swallowing.
- Amylase's Role: Amylase breaks down starches.
- Vitamin Absorption: The small intestine absorbs vitamins.
- Rectum Function (again): The rectum stores feces until elimination.
- Liver's Purging: The liver purifies blood, removing harmful substances.
- Stomach Acid and Enzyme Mixing: The stomach combines food with acid and enzymes for effective digestion.
- Pancreas Enzyme Production: The pancreas produces enzymes to help with digestion.
- Pancreatic Hormone: Insulin, produced by the pancreas, helps regulate blood sugar levels.
- Gallbladder Storage: The gallbladder stores bile.
- Large Intestine's Main Role: The large intestine is primarily responsible for absorbing water.
- Why Saliva is important: Saliva softens and moistens food so it moves through the esophagus smoothly, and easily.
- Consequences of Insufficient Stomach Acid: Insufficient stomach acid can be associated with impaired breakdown of proteins and starches.
- Jejunum's Absorption Benefit: The jejunum absorbs most nutrients due to its extensive surface area.
