Cardiovascular + respiratory
Edexcel GCSE Physical Education revision on Cardiovascular + respiratory. Aligned to the Pearson Edexcel GCSE PE 1PE0 specification. This bank has 7 practice questions on this topic.
Sample questions (3 of 7)
-
Question 1
Oxygenated blood is pumped from the heart by which chamber?
- A) Right atrium
- B) Right ventricle
- C) Left atrium
- D) Left ventricle
Show answer
Answer: Left ventricle
Heart's 4 chambers: RIGHT ATRIUM (receives deoxygenated blood from body), RIGHT VENTRICLE (pumps it to lungs), LEFT ATRIUM (receives oxygenated blood from lungs), LEFT VENTRICLE (pumps oxygenated blood to body). LEFT VENTRICLE has thickest muscle - has to push blood to the whole body.

Question 2
Heart rate is measured in...
- A) Litres per minute
- B) Beats per minute (BPM)
- C) Calories per hour
- D) Watts
Show answer
Answer: Beats per minute (BPM)
Resting HR: 60-100 BPM (adults). Lower = fitter. Maximum HR = 220 - age. EFFECT OF EXERCISE: HR rises rapidly at start of exercise, plateaus at submaximal intensity, returns to resting after stopping. Recovery rate (how fast HR returns to normal) is an indicator of fitness.

Question 3
Stroke volume is...
- A) Total blood in body
- B) Volume of blood ejected per beat of the heart
- C) Heart size
- D) Calories burned
Show answer
Answer: Volume of blood ejected per beat of the heart
SV typically ~70 mL at rest. Higher in trained athletes (~120 mL). CARDIAC OUTPUT (Q) = HR x SV - total blood pumped per minute. Q can rise from ~5 L/min at rest to ~25 L/min in elite athletes during exercise (5x increase).
