Where does mechanical digestion in man start?

• mouth

• esophagus

• stomach

• small intestine

What part of the digestive system connects the mouth to the stomach?

• pharynx

• esophagus

• small intestine

• large intestine

How do these villi help the digestive process?

• They protect the intestine from acid

• They break food into smaller pieces

• They move food faster through the intestines

• They increase the surface area for nutrient absorption

Which part of the digestive system is the doctor talking about?

• Esophagus

• Small intestine

• Stomach

• Large intestine

Which pair correctly matches each with its principal function?

• Small intestine - elimination; Large intestine - nutrient absorption

• Small intestine - mechanical digestion; Large intestine - chemical digestion

• Small intestine - nutrient absorption; Large intestine - water absorption and waste formation

• Small intestine - acid production; Large intestine - bile storage

Which strategy should be prioritized to address the most common issue for diarrhea?

• Educate students about chewing food thoroughly to prevent GERD.

• Increase fiber intake in the school menu to reduce constipation.

• Promote proper handwashing and food safety to prevent diarrhea.

• Encourage more caffeinated drinks to improve digestion

Which two systems work together to handle food and waste?

• Circulatory and muscular

• Digestive and excretory

• Respiratory and skeletal

• Nervous and reproductive

How do the digestive and circulatory systems work together to make this happen?

• The circulatory system absorbs nutrients, and the digestive system carries oxygen

• The digestive system breaks down food and the circulatory system delivers nutrients to body cells

• The circulatory system digests fats and the digestive system moves blood

• Both systems remove solid waste from the body

What role does the stem primarily play in the plant's transport system?

• It absorbs minerals from the soil

• It produces food through photosynthesis

• It carries water and nutrients between roots and leaves

• It stores food and water

Why are the leaves of the broken-stem plant turning yellow?

• The roots are absorbing too much sunlight

• Water and nutrients can't reach the leaves through the damaged stem

• The leaves are not exposed to enough air

• The roots are no longer attached to the soil
