The Human Respiratory System

• The human respiratory system is responsible for the inhalation of oxygen and the exhalation of carbon dioxide.
• It consists of the following parts:

1. Nostrils
2. Nasal passage
3. Pharynx
4. Larynx
5. Trachea
6. Primary Bronchi
7. Secondary Bronchi
8. Tertiary Bronchi
9. Bronchioles
10. Terminal Bronchioles
11. Alveoli

• In the given diagram we can identify the following:

W - Larynx

• The larynx is the 'voice box' of humans.
• It has flaps that vibrate when sound is pushed through them, thereby creating sound.

X - Trachea

• The trachea is a long straight tube that connects the nasal passage with the lungs.
• It is supported by incomplete cartilaginous rings.

Y - Bronchiole

• Bronchioles are small branches in the respiratory pathway that conduct air till the alveoli.

Z- Bronchi

• The trachea divides into the primary bronchi at the level of the fifth thoracic vertebra.
• Bronchi give rise to bronchioles.

Therefore, the correct option is (d).
