Task: Solve the problems related to the Respiratory System

#### 1) Unscramble the parts of the Respiratory System

We need to unscramble the given words to identify the parts of the respiratory system.

- a) otniris → sinus
- b) nyxrahp → pharynx
- c) airxny → naryx (likely a typo, should be "narynx" or "nasal cavity")
- d) gunl → lung
- e) bohcsunr → bronchus
- f) aipgamrhd → diaphragm
- g) rbhcio → ribcage
- h) noceilhorb → bronchiole
- i) aievoll → alveoli
- j) otuhm → mouth
- k) rhthcaa → trachea

#### 2) Label the parts on this diagram of the Respiratory System

Using the unscrambled words from part 1, we can label the diagram:

1. Nasal cavity (already labeled)
2. Pharynx
3. Trachea
4. Bronchi
5. Lungs
6. Diaphragm

#### 3) Find the parts of the Respiratory System in the word search

The word search grid contains hidden words related to the respiratory system. Let's find them:

- OXYGEN
- CARBON DIOXIDE
- TRACHEA
- BRONCHI
- ALVEOLI
- DIAPHRAGM
- PHARYNX
- NOSE
- MOUTH
- LUNGS
- RIBCAGE

#### 4) Select one or two parts and describe what they are used for in the Respiratory System

Let’s choose alveoli and trachea to describe their functions:

- Alveoli: These are tiny air sacs located at the end of the bronchioles in the lungs. They are responsible for gas exchange, where oxygen from the air diffuses into the bloodstream and carbon dioxide from the blood diffuses into the air to be exhaled. Alveoli have a large surface area and are surrounded by capillaries, which facilitates efficient gas exchange.

- Trachea: Also known as the windpipe, the trachea is a tube that connects the larynx (voice box) to the bronchi. It serves as the main passageway for air to travel into and out of the lungs. The trachea is reinforced with C-shaped cartilage rings to keep it open and allow smooth airflow during breathing.
