Human Body Systems Jeopardy
A hiker is climbing a steep trail. Solve each clue to reveal how body systems work alone and together. Choose one answer for multiple-choice questions; write clearly for the others.
Round 1: Power and Fuel
Clues about breathing, blood, and digestion.
1.A hiker's working muscles need oxygen. Which organ pumps blood so oxygen can travel around the body?
- Brain
- Heart
- Stomach
- Kidneys
2.During a deep breath, which gas enters the lungs and can pass into the blood?
3.Tiny air sacs in the lungs are where oxygen moves into the blood and carbon dioxide moves out. What are these sacs called?
- Alveoli
- Arteries
- Bronchi
- Tendons
4.Put the food's journey in order by writing 1, 2, 3, and 4 beside the steps: ___ stomach breaks food down; ___ food is chewed in the mouth; ___ nutrients are absorbed in the small intestine; ___ food moves down the esophagus.
Round 2: Control and Movement
The hiker changes pace, steps over a rock, and keeps climbing.
5.The hiker notices a loose rock and decides to step around it. Which organ is the main control center that interprets information and directs the response?
- Heart
- Brain
- Lung
- Stomach
6.Messages travel between the brain, spinal cord, and body along branching pathways. What are these pathways called?
7.The hiker's leg muscles contract to climb. Which statement best describes skeletal muscles?
- They usually move bones and can be controlled consciously.

- They digest food in the stomach.
- They carry messages through the body.
8.The heart keeps beating while the hiker focuses on the trail. What type of muscle makes up the heart?
Final Round: Systems Team Up
Explain how body systems cooperate during activity.
9.After a long climb, the hiker breathes faster and the heart beats faster. Explain how the respiratory and circulatory systems work together to help the muscles.
10.Why does the hiker's body need the digestive system? Include what happens to food and how the useful materials help the body.
