What structure is used by both the respiratory and digestive systems?
Esophagus
Paranasal sinuses
Larynx
Oropharynx
Nasopharynx - Answers Oropharynx
The oropharynx is a part of the throat located between the oral cavity and the nasopharynx. It serves as
a common pathway for both the respiratory and digestive systems. During respiration, air passes
through the oropharynx on its way to the larynx and then to the lower respiratory tract. During
swallowing, food and liquids pass through the oropharynx on their way to the esophagus, which is part
of the digestive system.
The nasopharynx, paranasal sinuses, and larynx are involved in the respiratory system, while the
esophagus is a key part of the digestive system.
Which is not a function of the respiratory system?
Air passageway
Sound reception
Odor detection
Gas exchange - Answers Sound reception
Sound reception is a component of the nervous system as specialized structures in the head are
responsible for perceiving and transducing vibrating waves into sound. Sound production, however, is a
responsibility of the respiratory system.
All other options are functions of the respiratory system.
Which components are part of the upper respiratory division? Select all that apply.
Alveoli
Nasal cavity
,Lungs
Trachea
Pharynx - Answers Nasal cavity
Pharynx
The upper respiratory tract consists of respiratory organs in the head and neck such as the nose, nasal
cavity, pharynx, and larynx.
The lower respiratory tract consists of the respiratory organs in the chest such as the trachea, lungs,
bronchi, bronchioles, and alveoli.
Which term encompasses the entire process of exchanging gases between an organism and its
environment?
Circulation
Ventilation
Oxygenation
Respiration - Answers Respiration
Respiration is the term that encompasses the entire process of exchanging gases between an organism
and its environment. It includes both the processes of ventilation (the mechanical movement of air in
and out of the lungs) and the actual exchange of gases between the lungs and the bloodstream (external
respiration) and between the bloodstream and body tissues (internal respiration).
Pulmonary ventilation (breathing) can also be described as
the movement of air into and out of the lungs
the process of expiration only
the process of gas exchange in the lungs only
the process of inspiration only. - Answers the movement of air into and out of the lungs
, Pulmonary ventilation, commonly referred to as breathing, is the process of moving air into and out of
the lungs. It includes both inspiration (the process of inhaling or taking air into the lungs) and expiration
(the process of exhaling or expelling air from the lungs).
What gas is generated as a waste product of cellular metabolism during internal respiration?
Carbon dioxide
Nitrogen
Hydrogen
Oxygen - Answers Carbon dioxide
How does the respiratory system contribute to communication?
It produces hormones that enhance communication skills.
It contains vocal cords that vibrate to produce sound.
It regulates body temperature for effective communication.
It filters air for speech clarity. - Answers It contains vocal cords that vibrate to produce sound.
The flow of air past the vocal cords in the respiratory system allows for the production of sounds and
vocalization, which is essential for verbal communication.
What is a primary function of the respiratory system?
Controlling immune response
Regulating body temperature
Facilitating gas exchange
Producing hormones for digestion - Answers Facilitating gas exchange
A primary function of the respiratory system is to facilitate the exchange of gases between the body and
the environment. This process involves inhaling oxygen from the air and exhaling carbon dioxide,
allowing for the supply of oxygen to body tissues and the removal of carbon dioxide, a waste product of
cellular metabolism.
In which type of respiration does oxygen in the bloodstream enter the body's cells for energy
production?
