🎯 Learning Intention & Success Criteria

Learning Intention: I can explain the structure and function of the human respiratory system and how gas exchange occurs.

Success Criteria - I can:

Label the main parts of the respiratory system

Describe the pathway air takes through my body

Explain how oxygen and carbon dioxide are exchanged

Identify adaptations that make gas exchange efficient

🔊 Dyslexia-friendly tip: Ask your teacher to read questions aloud if helpful

Curriculum: NZ-TMA-SCIENCE-Y9-10-biological-science-122-DOC205 & 126-DOC205

📋 Part 1: Respiratory System Knowledge

1. Label the diagram of the respiratory system using these words:

Word bank: nose, trachea, bronchi, bronchioles, alveoli, lungs, diaphragm, ribs

2. Match each part to its function:

A. Alveoli

B. Trachea

C. Diaphragm

D. Bronchioles

1. Muscle that helps breathing

2. Tiny air sacs for gas exchange

3. Windpipe to the lungs

4. Smallest airways in lungs

3. Put the pathway of air in the correct order (1-6):

____ Alveoli

____ Bronchi

____ Bronchioles

____ Nose/mouth

____ Trachea

____ Lungs

4. What happens during breathing in (inspiration)?

Diaphragm moves up, ribs move in

Diaphragm moves down, ribs move out

Diaphragm stays still, ribs move in

🧠 Part 2: Gas Exchange & Application

5. Explain how oxygen gets from the alveoli into your blood:

6. List THREE adaptations of alveoli that make gas exchange efficient:

7. Data Question: At rest, you breathe about 15 times per minute. During exercise, this increases to 30 times per minute. Calculate how many more breaths you take in 10 minutes of exercise compared to 10 minutes at rest:

8. How do the respiratory and circulatory systems work together?

🌟 Extension Challenge (Advanced learners):

Research and explain why people living at high altitude (like mountain climbers) often have more red blood cells. How does this help their respiratory system?
