Which of the following is the main function of the respiratory system?
Obtains oxygen and remove carbon dioxide from the body
Transports oxygen and nutrients to the body cells
Protects the body from invading organisms
Which of the following is the correct pattern of airflow inhalation?
NASAL CAVITY-PHARYNX-TRACHEA-BRONCHI-BRONCHIOLES-LUNGS
NASAL CAVITY-PHARYNX-ALVEOLI-BRONCHI-BRONCHIOLES-LUNGS
NASAL CAVITY-THROAT-LARYNX-WINDPIPE-BRONCHI-LUNGS
Which of the following is the main muscle for breathing?
Intercostal Muscle
Diaphragm
Sternocleidomastoid
Aside from being part of the respiratory way, what is the other function of the larynx?
It has a small tissue called epiglottis that directs the food to the esophagus.
It contains the tissues where the gas exchange happens.
It contains the vocal cord that allows the body to produce sound.
During inhalation, contraction of the diaphragm and the intercostal muscle cause the lung /thoracic cavity to __________ and the air pressure in lungs to _____________.
Contract; Decrease
Expand: Increase
Contract; Increase
What is the anatomically correct name of the windpipe?
Pharynx
Larynx
Trachea
Which of the following is the function of alveoli in respiration?
Helping the lungs to stay inflated
Gaseous exchange
Relaxation
Which of the following structures is NOT part of the upper respiratory tract?
lungs
epiglottis
pneumothorax
The cells that make and secrete mucus that protects the lining of the respiratory tract are called:
alveolar cells
goblet cells
pneumothorax
Ventilation (breathing) is a regular, rhythmic process which:
moves air into and out of the lungs
protects the airways by clearing them of mucus or irritants
moves gases from an area of high concentration to an area of lower concentration
When the diaphragm and intercostal muscles contract during expiration, the lung volume is reduced
FACT
BLUFF
Living cells need a continuous supply of oxygen
FACT
BLUFF
During expiration, the diaphragm flattens and the ribcage enlarges, lowering the pressure in the lungs
FACT
BLUFF
The two openings of the airway (the nasal cavity and the mouth) meet at the larynx
FACT
BLUFF
Oxygen moves from alveoli to the blood capillaries that line the alveolar walls
FACT
BLUFF
The function of the nose is to filter, warm, and moisten the air as you breathe in
FACT
BLUFF
The lungs are covered with moist tissue known as pleura.
FACT
BLUFF
The tension and speed of vibration of the vocal cords can vary the pitch.
FACT
BLUFF
When vocal cords are long and relaxed, they produce high notes
FACT
BLUFF
The size of the chest cavity decreases when we take in air and increases when we give off.
FACT
BLUFF
