Based on the analysis of the diagram and the provided word bank, here is the solution for labeling the parts of the respiratory system. The labels are listed in order from top to bottom, following the lines as they appear on the left side of the diagram, then moving to the right side.
Left Side Labels (Top to Bottom):
1.
Paranasal Sinuses: The air-filled cavities within the skull bones surrounding the nasal cavity.
2.
Nasal Cavity: The large space inside the nose where air is filtered, warmed, and humidified.
3.
Nostrils: The external openings of the nasal cavity.
4.
Oral Cavity: The mouth, which serves as an alternative pathway for air to enter the body.
5.
Pharynx: The throat, a muscular tube that serves as a passageway for both air and food.
6.
Larynx: The voice box, located at the top of the trachea, containing the vocal cords.
7.
Trachea: The windpipe, a tube reinforced with cartilage rings that carries air to and from the lungs.
8.
Left Lung: One of the two primary organs of respiration, located on the left side of the chest.
9.
Inferior Lobe: The bottom section of the lung.
10.
Diaphragm: The large, dome-shaped muscle at the base of the thoracic cavity that contracts and relaxes to facilitate breathing.
Right Side Labels (Top to Bottom):
1.
Epiglottis: A flap of cartilage located at the root of the tongue that prevents food and liquid from entering the trachea during swallowing.
2.
Left/Right Primary Bronchus: The main airway that branches off from the trachea to enter each lung.
3.
Bronchi: The larger airways branching from the primary bronchi into the lobes of the lungs.
4.
Bronchioles: The smaller branches of the bronchi that lead to the alveoli.
5.
Alveoli: Tiny, balloon-like sacs at the end of the bronchioles where gas exchange (oxygen and carbon dioxide) occurs between the air and the blood.
6.
Superior Lobe: The top section of the lung.
7.
Middle Lobe: The middle section of the lung (specifically the right lung).
8.
Left/Right Lung: This label points to the entire lung structure on the right side. Since "Left/Right Lung" is in the word bank, it can be used to label either lung, though the diagram shows the right lung cut open.
9.
Inferior Lobe: The bottom section of the lung (on the right side).
Parent Tip: Review the logic above to help your child master the concept of labeling the respiratory system worksheet.
