In a constructed lung model, each part represents a specific component of the respiratory system. The main components and their representations are:
-
Lungs: The small balloons inside the bottle represent the lungs. In the human body, the lungs are the organs responsible for the exchange of oxygen and carbon dioxide during the breathing process.
-
Chest cavity and rib cage: The bottle itself represents the chest cavity and rib cage. The chest cavity is the space in the body where the lungs are located, and the rib cage protects the lungs and other organs in the chest.
-
Diaphragm: The plastic tube connected to the big balloons represents the diaphragm. In the human body, the diaphragm is a muscle that separates the chest cavity from the abdominal cavity and plays a crucial role in the breathing process by expanding and contracting.
-
Trachea: The upper part of the straw represents the trachea. The trachea is a tube that connects the throat to the lungs and allows air to pass through.
-
Bronchioles: The parts of the straw just above the small balloons represent the bronchioles. Bronchioles are small airways in the lungs that branch out from the trachea and carry air to the alveoli.
-
Alveoli: The part of the bottle that covers the bronchioles represents the alveoli. Alveoli are tiny sacs in the lungs where the exchange of oxygen and carbon dioxide takes place between the air and the blood.
-
Diaphragm movement: The movement of the balloon at the bottom of the model represents the movement of the diaphragm during the breathing process. When the diaphragm contracts, it moves downward, causing the lungs to expand and fill with air. When the diaphragm relaxes, it moves upward, causing the lungs to deflate and release carbon dioxide.
