Questions and Answers
Which process best describes the function of peristalsis in the esophagus?
Which process best describes the function of peristalsis in the esophagus?
- Breaking down food particles into smaller molecules for easier digestion.
- Moving swallowed food towards the stomach through wavelike muscle contractions. (correct)
- Neutralizing stomach acids before they enter the esophagus.
- Preventing air from entering the digestive tract during swallowing.
What is the primary role of the esophageal sphincter?
What is the primary role of the esophageal sphincter?
- To regulate the rate at which food enters the small intestine.
- To prevent air from entering the esophagus and prevent reflux of food and acid. (correct)
- To secrete enzymes that aid in the breakdown of proteins.
- To absorb nutrients from digested food before it enters the stomach.
How does the pancreas assist in the digestive process as an accessory organ?
How does the pancreas assist in the digestive process as an accessory organ?
- By filtering toxins and waste products from the blood.
- By secreting a juice loaded with enzymes to break down proteins, carbohydrates, and fats. (correct)
- By producing bile to emulsify fats.
- By storing and concentrating bile produced by the liver.

Study Notes
- Telophase in mitosis concludes nuclear division, resulting in two identical nuclei.
- The oral cavity is the entry point to the digestive system where ingestion takes place.
- The tongue, a muscular organ, detects taste and aids in swallowing by pushing food to the pharynx.
- The esophageal sphincter prevents air from entering the esophagus and stops food and acid reflux.
- The stomach receives food from the esophagus and uses acids to partially digest it for nutrient absorption.
- Chyme is an acidic substance produced in the stomach that moves to the small intestine for further nutrient absorption.
- Peristalsis involves wavelike muscle contractions in the esophagus that move food towards the stomach.
- The liver is an accessory digestive organ that supports digestion from outside the digestive tract.
- The pancreas secretes enzyme-rich juice to aid the breakdown of proteins, carbohydrates, and fat-soluble vitamins.
- The appendix is a vestigial organ with no essential digestive function.
- The large intestine absorbs water and salts from digested food before waste moves to the rectum.
- Excessive carbohydrate consumption can lead to exhaustion, cramps, fatigue, memory loss, learning difficulties, epilepsy, and paralysis.
- Prophase is the stage where chromatin condenses into distinct chromosomes.
- Mitosis is a type of cell division that creates two identical daughter cells from a single parent cell.
- Cell division is the process by which cells multiply to create more cells.
- The cell cycle is a growth process that allows cells in the body to grow and repair tissue.
- Vitamin C is also known as ascorbic acid.
- Vitamin D supports bone and teeth growth and calcium absorption in the body.
- Proteins are essential for building and repairing body tissues.
