Respiratory System Flashcards
What is the primary function of the respiratory system?
To facilitate gas exchange, primarily oxygen intake and carbon dioxide removal.
True or False: The diaphragm is a muscle that plays a crucial role in respiration.
True
Fill in the blank: The __________ is the passage that leads from the nose to the lungs.
trachea
What are the tiny air sacs in the lungs called where gas exchange occurs?
Alveoli
Multiple choice: Which structure is responsible for producing sound?
Larynx
What is the term for the process of breathing in?
Inhalation
What is the term for the process of breathing out?
Exhalation
True or False: The upper respiratory tract includes the nose, pharynx, and larynx.
True
What is the primary gas that is exchanged in the alveoli?
Oxygen
Multiple choice: Which of the following structures is NOT part of the lower respiratory tract?
Nasal cavity
What is the role of the cilia in the respiratory system?
To trap and expel foreign particles and pathogens.
Fill in the blank: The __________ are two large organs located in the thoracic cavity.
lungs
What is the function of the pleura?
To reduce friction between the lungs and chest wall during breathing.
True or False: The respiratory system works independently of the circulatory system.
False
What is the name of the condition characterized by difficulty in breathing?
Dyspnea
Multiple choice: Which of the following is a common respiratory condition?
Asthma
What is the function of surfactant in the lungs?
To reduce surface tension in the alveoli.
Fill in the blank: The __________ helps to warm and humidify the air we breathe.
nasal cavity
What is the term for the volume of air inhaled or exhaled in a normal breath?
Tidal volume
True or False: The respiratory system does not play a role in regulating blood pH.
False
What is the main muscle involved in the process of inhalation?
Diaphragm
Multiple choice: Which part of the brain regulates the rate of breathing?
Medulla oblongata
What is the role of hemoglobin in the respiratory system?
To transport oxygen in the blood.
Fill in the blank: The __________ is located at the back of the throat and connects to the esophagus and trachea.
pharynx
True or False: Smoking can lead to chronic obstructive pulmonary disease (COPD).
True
What is the process of exchanging oxygen and carbon dioxide between the blood and tissues called?
Internal respiration
Multiple choice: Which of the following is a part of the conducting zone of the respiratory system?
Bronchi
What condition is characterized by inflammation of the airways and difficulty breathing?
Asthma
Fill in the blank: The __________ is the flap that covers the trachea during swallowing.
epiglottis
True or False: The alveoli are surrounded by capillaries.
True
What is the primary role of the nasal conchae?
To increase surface area for warming and humidifying air.
Multiple choice: Which gas is primarily expelled during exhalation?
Carbon dioxide
What is the term for the maximum amount of air that can be exhaled after a maximum inhalation?
Vital capacity
Fill in the blank: The __________ are small tubes that lead from the trachea to the alveoli.
bronchioles
True or False: The respiratory system is only responsible for gas exchange.
False
