Explanations: answer key for all 10 questions

Q1: What is the medical name for the windpipe?
Answer: Trachea
Rings of cartilage keep it open.
Q2: What are the two main branches of the windpipe called?
Answer: Bronchi
One goes to each lung.
Q3: In which tiny air sacs does gas exchange happen?
Answer: Alveoli
There are hundreds of millions of them.
Q4: The alveoli together have a surface area about the size of what?
Answer: A tennis court
This large area helps absorb oxygen.
Q5: Which muscle contracts to make you breathe in?
Answer: Diaphragm
It flattens and enlarges the chest.
Q6: Which gas do we breathe out more of than we breathe in?
Answer: Carbon dioxide
It is a waste product of respiration.
Q7: Why is the left lung slightly smaller than the right?
Answer: To make room for the heart
The left lung has two lobes; the right has three.
Q8: What mainly triggers the urge to breathe?
Answer: Rising carbon dioxide levels
The brainstem monitors blood CO2.
Q9: What is a typical adult resting breathing rate?
Answer: About 12 to 20 breaths per minute
It rises during exercise.
Q10: What tiny hairs in airways help sweep out dust?
Answer: Cilia
Mucus traps particles.

Lungs And Breathing Trivia – The Breath of Life

Breathing brings oxygen into the body and removes carbon dioxide. Air travels through the nose or mouth, down the trachea, into the bronchi and finally to millions of tiny air sacs called alveoli.

In the alveoli, oxygen passes into the blood and carbon dioxide passes out to be exhaled. Their huge combined surface area, about the size of a tennis court, makes this exchange fast and efficient.

The diaphragm and rib muscles power breathing, controlled by the brainstem. Clean air, exercise and not smoking keep lungs healthy, while conditions like asthma can narrow the airways.
