Digestive System Structure

What are the main organs of the digestive system?

• Heart, lungs, kidneys, brain

• Spleen, pancreas, gallbladder, bladder

• Mouth, esophagus, stomach, small intestine, large intestine, and liver

• Skin, bones, muscles, blood vessels

Describe the structure and function of the esophagus.

• The esophagus is a small pouch that stores food before it enters the stomach.

• The esophagus is a bone that helps in chewing food.

• The esophagus is a long, thin tube that connects the stomach to the small intestine.

• The esophagus is a muscular tube that transports food from the mouth to the stomach.

Explain the role of the stomach in the digestive system.

• The stomach breaks down food and helps in the absorption of nutrients.

• The stomach filters out toxins from the food before it enters the small intestine.

• The stomach produces insulin to regulate blood sugar levels.

• The stomach stores waste before it is eliminated from the body.

What is the function of the small intestine in digestion?

• Production of stomach acid

• Storage of waste

• Regulation of blood sugar levels

• Absorption of nutrients

Discuss the structure and function of the large intestine.

• The large intestine absorbs water and electrolytes from undigested food, and forms and expels feces.

• The large intestine is responsible for producing digestive enzymes

• The large intestine has no role in the digestive process

• The large intestine is where most nutrient absorption occurs

How does the liver contribute to the digestive process?

• Produces insulin to break down carbohydrates

• Produces bile to aid in fat digestion

• Regulates blood sugar levels

• Stores excess water for the body

Explain the role of the pancreas in the digestive system.

• Stores bile

• Regulates blood sugar

• Produces digestive enzymes

• Produces red blood cells

Describe the structure and function of the gallbladder.

• The gallbladder is a muscular organ that helps in pumping blood throughout the body.

• The gallbladder is a part of the respiratory system and helps in breathing.

• The gallbladder produces insulin to regulate blood sugar levels.

• The gallbladder stores and concentrates bile produced by the liver, releasing it into the small intestine to aid in digestion.

Discuss the importance of the digestive system's nervous system in controlling digestion.

• It only controls the sense of taste

• It has no role in controlling digestion

• It controls the movement of food through the digestive tract, the release of digestive enzymes, and the sensation of hunger and fullness.

• It is responsible for regulating body temperature
