Resiratory Anatomy and Physiology

What is the difference between the upper and lower respiratory tracts?

• The upper respiratory tract includes the nose, nasal cavity, and pharynx, while the lower respiratory tract includes the larynx, trachea, bronchi, and lungs.

• The upper respiratory tract includes the larynx and trachea, while the lower respiratory tract includes the nose and nasal cavity.

• The upper respiratory tract is responsible for gas exchange, while the lower respiratory tract filters air.

• The upper respiratory tract includes the bronchi and lungs, while the lower respiratory tract includes the nose and pharynx.

What is the role of the nasal cavity in respiration?

• The nasal cavity filters, warms, and moistens the air before it enters the lungs.

• The nasal cavity is responsible for gas exchange in the lungs.

• The nasal cavity produces mucus to trap pathogens and particles.

• The nasal cavity regulates blood flow to the lungs.

What opening does the epiglottis cover?

• The nasal cavity

• The glottis/trachea

• The esophagus

• The larynx

Where is the pleural cavity located?

• Between the parietal pleura and the visceral pleura.

• In the abdominal cavity.

• Within the mediastinum.

• Surrounding the heart.

What is the function of the diaphragm in respiration?

• It helps in the exchange of gases in the lungs.

• It contracts to create a vacuum that pulls air into the lungs during inhalation.

• It regulates the temperature of the air entering the lungs.

• It prevents food from entering the trachea during swallowing.

What are the main components of the respiratory system?

• Nose, pharynx, larynx, trachea, bronchi, lungs, and alveoli

• Heart, arteries, veins, and capillaries

• Stomach, intestines, liver, and pancreas

• Skin, hair, nails, and sweat glands

Which part of the Respiratory System collects air from the environment & heats/moistens the air before entering the body?

• The mouth.

• The trachea.

• The nose.

• The lungs.

What is the difference between inhalation and exhalation?

• Inhalation is the process of taking air into the lungs, while exhalation is the process of expelling air from the lungs.

• Inhalation is the process of expelling air from the lungs, while exhalation is the process of taking air into the lungs.

• Inhalation occurs only during physical exercise, while exhalation occurs at rest.

• Inhalation is the process of breathing out, while exhalation is the process of breathing in.

What is the primary function of the respiratory system?

• To facilitate gas exchange, providing oxygen to the body and removing carbon dioxide.

• To circulate blood throughout the body.

• To digest food and absorb nutrients.

• To regulate body temperature and maintain homeostasis.

What is the role of alveoli in the respiratory system?

• Alveoli are responsible for producing mucus in the lungs.

• Alveoli are tiny air sacs where gas exchange occurs between the air and the bloodstream.

• Alveoli help in the mechanical process of breathing by expanding and contracting.

• Alveoli are involved in filtering dust and particles from the air.
