Which organ in the respiratory system is known as the voice box?
Larynx
Where is the trachea situated in the human body?
In the front of the neck
Match the following organs with their descriptions:
Nasal cavity = First part of the respiratory system where air is warmed and filtered Larynx = Rectangular chamber that produces sound and is known as the voice box Trachea = Delicate muscular tube with C-shaped rings of cartilage to keep the lumen open Bronchi = Air passages that branch from the trachea into the lungs
Match the following respiratory system components with their functions:
Nasal cavity = Warms and filters air as it enters the nose Larynx = Produces sound and acts as the voice box Trachea = Keeps the lumen open with C-shaped rings of cartilage Lungs = Organs where oxygen is absorbed and carbon dioxide is released
Match the following respiratory system components with their positions in the human body:
Nasal cavity = First part of the respiratory system located in the nose Larynx = Connects the pharynx and trachea in the throat Trachea = Situated in the front of the neck and extends to the bronchi Bronchi = Branches from the trachea and leads into the lungs
Match the following respiratory system components with their anatomical features:
Nasal cavity = Divided into two parts by a septum Larynx = Guarded by the epiglottis at the opening from the pharynx Trachea = Consists of delicate muscular tube with C-shaped rings of cartilage Bronchi = Air passages that branch from the trachea and lead into the lungs
Match the following respiratory system components with their roles in respiration:
Nasal cavity = Warms and filters air as it enters the respiratory system Larynx = Produces sound and controls the flow of air into the trachea Trachea = Passageway for air to travel into the lungs Bronchi = Divide from the trachea and carry air into the lungs
