Step 1
Outline the function of the digestive system.
Answer
The digestive system has several key functions. It breaks down food into smaller, absorbable nutrients, ensuring that the body can utilize them effectively. Foods are ingested, digested, and then transformed into usable energy and building materials. Additionally, it helps eliminate waste by expelling indigestible substances.
Step 2
Step 3
Select any two of the parts you have named and outline their role in digestion.
Answer
- Mouth: The mouth plays a crucial role in physically breaking down food through chewing. Saliva is mixed with food, beginning the chemical digestion process, which aids in breaking down carbohydrates.
- Small intestine: The small intestine is vital for nutrient absorption. It receives digestive juices from the pancreas and liver, facilitating the breakdown of food into smaller particles for absorption into the bloodstream.
Step 4
Suggest some guidelines that should be followed to promote a healthy digestive system.
Answer
- Eat a diet high in fiber to support digestion.
- Visit the doctor if experiencing any stomach complaints or ulcers.
- Take a probiotic yogurt or drink daily to promote healthy gut bacteria.
- Limit alcohol consumption to reduce irritation to the digestive system.
Step 5
What are digestive enzymes?
Answer
Digestive enzymes are biological catalysts that facilitate the breakdown of food into simpler molecules. They are secreted by various organs in the digestive system and work to convert complex foods into smaller particles that can be easily absorbed by the body. Each enzyme is specific to a particular type of nutrient, aiding in the efficient digestion of food.
