🫁 Part 1: System Knowledge

WALT: Explain how the respiratory and circulatory systems interact to transport gases and nutrients throughout the body.

1. Which gas does your body need to take in from the air?

Carbon dioxide

Oxygen

Nitrogen

Hydrogen

2. What connects your lungs to your heart to transport gases?

Arteries and veins

Muscles

Bones

Nerves

3. Complete the sentence: When you breathe in, oxygen travels from your lungs into your __________ and is pumped around your body by your __________.

4. Draw and label a simple diagram showing how oxygen moves from your lungs to your heart and then to your muscles.

🏃 Part 2: Exercise Investigation

WALT: Investigate how the respiratory and circulatory systems respond to the body's needs during exercise.

5. Record your heart rate and breathing rate data in the table below. Count for 15 seconds and multiply by 4 to get beats/breaths per minute.

Data Collection Table:

Resting Heart Rate: _____ beats per minute

Resting Breathing Rate: _____ breaths per minute

After 2 minutes exercise - Heart Rate: _____ beats per minute

After 2 minutes exercise - Breathing Rate: _____ breaths per minute

After 5 minutes rest - Heart Rate: _____ beats per minute

After 5 minutes rest - Breathing Rate: _____ beats per minute

6. Explain why your heart rate and breathing rate changed during exercise.

7. What happens to your muscles during exercise that makes them need more oxygen?
