Step-by-step solution for: Respiratory System worksheets.pdf
Let's solve this worksheet step by step using the words provided in the box:
Words in the box:
- air
- oxygen
- inhale
- exhale
- lungs
- trachea
- respiratory
- bronchi
- carbon dioxide
- diaphragm
- water vapor
- mucus
- nose
- yawn
- cough
- pharynx
- sneeze
- blood

> All animals need oxygen to make energy from food. We get this oxygen from the air that we breathe. In order to get this oxygen into the blood where it can be transported to the rest of the body, the air travels through a system of organs called the respiratory system.
✔ Explanation:
- Animals need oxygen for cellular respiration (energy production).
- Oxygen comes from the air we breathe.
- The system responsible is the respiratory system.
---
> When you inhale or the yawn, air enters the body through the nose or the mouth. From there it passes through the pharynx, which forces air into the trachea and food into the esophagus. The air travels down the trachea into two branching tubes called bronchi and then on into the lungs.
✔ Explanation:
- Inhale means to breathe in; yawn is also a way air enters.
- Air enters via nose or mouth.
- Then goes through pharynx (throat), which directs air to trachea (windpipe) and food to esophagus.
- Trachea splits into bronchi (plural of bronchus), leading to lungs.
---
> In the lungs oxygen from the air enters the blood. At the same time, the waste gas carbon dioxide leaves the blood and then leaves the body when you exhale. Some water vapor also leaves the body when you exhale, which is why mirrors get foggy when you breathe on them. The diaphragm is the muscle that controls the lungs.
✔ Explanation:
- Oxygen diffuses into blood in the alveoli of the lungs.
- Carbon dioxide (waste product) moves from blood into lungs.
- It exits during exhale (breathing out).
- Water vapor is released with exhaled breath — causes condensation on mirrors.
- The diaphragm contracts and relaxes to help breathing.
---
> It is important to keep the respiratory system clear so oxygen can keep flowing into your body. If something gets in your nose and irritates it, you sneeze. If something gets in your trachea or bronchi and irritates it, you cough. If something irritates your diaphragm, you hiccup. Finally, if the brain thinks you are not getting enough oxygen, then it forces you to inhale.
✔ Explanation:
- Sneeze: Reflex to clear nasal passages.
- Cough: To clear trachea or bronchi.
- Hiccup: Sudden contraction of diaphragm (often due to irritation).
- Inhale: Brain triggers breathing reflex if oxygen levels drop.

✔ Final Answer (Completed Passage):
All animals need oxygen to make energy from food. We get this oxygen from the air that we breathe. In order to get this oxygen into the blood where it can be transported to the rest of the body, the air travels through a system of organs called the respiratory system.
When you inhale or the yawn, air enters the body through the nose or the mouth. From there it passes through the pharynx, which forces air into the trachea and food into the esophagus. The air travels down the trachea into two branching tubes called bronchi and then on into the lungs.
In the lungs oxygen from the air enters the blood. At the same time, the waste gas carbon dioxide leaves the blood and then leaves the body when you exhale. Some water vapor also leaves the body when you exhale, which is why mirrors get foggy when you breathe on them. The diaphragm is the muscle that controls the lungs.
It is important to keep the respiratory system clear so oxygen can keep flowing into your body. If something gets in your nose and irritates it, you sneeze. If something gets in your trachea or bronchi and irritates it, you cough. If something irritates your diaphragm, you hiccup. Finally, if the brain thinks you are not getting enough oxygen, then it forces you to inhale.
