The worksheet asks you to label the parts of the human respiratory system using the word bank provided. Based on the lines pointing to each part in the diagram, here are the correct labels:
Upper Respiratory Tract:
*
Nasal Cavity: The space inside the nose.
*
Mouth: The oral opening.
*
Oral Cavity: The space inside the mouth.
*
Epiglottis: The small flap that covers the windpipe when you swallow.
*
Pharynx: The throat area behind the mouth and nasal cavity.
*
Larynx: The voice box, located below the pharynx.
Lower Respiratory Tract:
*
Trachea: The windpipe, the tube leading down from the larynx.
*
Right Lung: The larger lung on the left side of the diagram (which is the body's right side).
*
Left Lung: The smaller lung on the right side of the diagram (which is the body's left side).
*
Bronchi: The two main tubes that branch off from the trachea into the lungs.
*
Bronchioles: The smaller branches inside the lungs.
*
Alveoli: The tiny air sacs at the end of the bronchioles (shown in the magnified circle).
Muscle:
*
Diaphragm: The large muscle at the bottom of the chest cavity that helps you breathe.
Final Answer:
Nasal Cavity, Mouth, Oral Cavity, Epiglottis, Pharynx, Larynx, Trachea, Right Lung, Left Lung, Bronchi, Bronchioles, Alveoli, Diaphragm
