The 10 quiz questions
Question 1 : Which organ is mainly responsible for breathing?
Possible answers:
- The liver
- The heart
- The stomach
- The lungs
Explanation: The lungs are the main organs of respiration. They enable gas exchange between air and blood: oxygen absorption and carbon dioxide release.
Question 2 : What is the main muscle that enables inhalation?
Possible answers:
- The biceps
- The diaphragm
- The abdominals
- The heart
Explanation: The diaphragm is the main breathing muscle. When it contracts, it lowers and increases the volume of the chest cavity, allowing air to enter the lungs.
Question 3 : What gas do we mainly absorb during inhalation?
Possible answers:
- Carbon dioxide
- Hydrogen
- Oxygen
- Nitrogen
Explanation: Oxygen (O₂) is the vital gas we absorb during inhalation. It makes up about 21% of the air we breathe and is essential for our cells to function.
Question 4 : Abdominal breathing is also called... breathing
Possible answers:
- Clavicular
- Bronchial
- Costal
- Diaphragmatic
Explanation: Diaphragmatic (or abdominal) breathing fully engages the diaphragm. The belly expands during inhalation as the diaphragm descends, unlike shallow chest breathing.
Question 5 : What breathing technique involves inhaling through the nose and exhaling slowly through the mouth?
Possible answers:
- Apnea
- Cardiac coherence
- Hyperventilation
- Box breathing
Explanation: Cardiac coherence is a slow, regular breathing technique (5-6 breaths per minute) that synchronizes the heart rate and reduces stress.
Question 6 : How many breaths per minute does an adult take at rest on average?
Possible answers:
- 5 to 8
- 8 to 10
- 12 to 20
- 30 to 40
Explanation: An adult at rest breathes on average 12 to 20 times per minute. This rate increases during physical exertion or stressful situations.
Question 7 : What effect does slow, deep breathing have on the body?
Possible answers:
- It relaxes and calms
- It excites and stimulates
- It causes fatigue
- It has no effect
Explanation: Slow breathing activates the parasympathetic nervous system, responsible for relaxation. It slows heart rate and lowers blood pressure.
Question 8 : What is voluntarily holding your breath called?
Possible answers:
- Apnea
- Asphyxiation
- Dyspnea
- Hyperventilation
Explanation: Apnea is the voluntary or involuntary cessation of breathing. It is practiced in certain sports (diving) and relaxation techniques.
Question 9 : In which discipline is breathing a central element of practice?
Possible answers:
- Yoga
- Tennis
- Weightlifting
- Swimming
Explanation: Yoga places breathing (pranayama) at its core. Breath exercises are considered essential for mastering body and mind.
Question 10 : Through which passage is it recommended to inhale to filter and warm the air?
Possible answers:
- The mouth
- The ears
- The nose
- It doesn't matter
Explanation: The nose filters, warms, and humidifies air before it reaches the lungs. Nose hairs and mucus trap particles and bacteria.
