The image provided is a diagram of the human respiratory system, and the task is to label the parts using the word bank provided. Below is the solution with explanations for each labeled part:
Word Bank:
- trachea
- alveoli
- nasal cavity
- larynx
- bronchiole
- diaphragm
- pharynx
- lung
- left bronchi
- right bronchi
- mouth cavity
Solution:
1.
Mouth cavity: This is the opening where air enters through the mouth.
2.
Nasal cavity: This is the area inside the nose where air can also enter.
3.
Pharynx: The throat area that connects the nasal cavity and mouth to the larynx.
4.
Trachea: Also known as the windpipe, it is the tube that carries air from the pharynx to the lungs.
5.
Left bronchi: One of the two main branches of the trachea that lead into the left lung.
6.
Right bronchi: One of the two main branches of the trachea that lead into the right lung.
7.
Larynx: Often called the voice box, it is located below the pharynx and above the trachea.
8.
Bronchiole: Smaller branches of the bronchi that further divide within the lungs.
9.
Lung: The organ where gas exchange occurs.
10.
Diaphragm: A muscle located at the base of the chest cavity that helps in breathing by contracting and expanding.
11.
Alveoli: Tiny air sacs in the lungs where oxygen and carbon dioxide are exchanged.
Final Labeled Diagram:
1. Mouth cavity
2. Nasal cavity
3. Pharynx
4. Trachea
5. Left bronchi
6. Right bronchi
7. Larynx
8. Bronchiole
9. Lung
10. Diaphragm
11. Alveoli
Explanation:
-
Mouth cavity (1): Air enters the respiratory system through the mouth.
-
Nasal cavity (2): Air can also enter through the nose, which warms, filters, and humidifies the air.
-
Pharynx (3): Common passageway for both air and food, connecting the nasal cavity and mouth to the larynx.
-
Trachea (4): A rigid tube that transports air to and from the lungs.
-
Left bronchi (5) and
Right bronchi (6): The primary branches of the trachea that lead into the left and right lungs, respectively.
-
Larynx (7): Contains the vocal cords and helps protect the trachea from food.
-
Bronchiole (8): Smaller tubes that branch off from the bronchi, leading to the alveoli.
-
Lung (9): The main organ of respiration where gas exchange occurs.
-
Diaphragm (10): A dome-shaped muscle that contracts during inhalation to expand the chest cavity and relaxes during exhalation.
-
Alveoli (11): Microscopic air sacs in the lungs where oxygen diffuses into the blood and carbon dioxide diffuses out.
This completes the labeling of the respiratory system diagram. Each part plays a crucial role in the process of breathing and gas exchange.
