Question 1
Which of the following terms is used to describe the
amount of air moved into or out of the lungs during a
normal inhalation or exhalation?
Correct Answer: Tidal volume
Detailed Professional Rationale:
Tidal volume is the amount of air inhaled or exhaled during a
normal, quiet breath. In a healthy adult at rest, it is
approximately 500 mL, although the actual value varies
according to body size and physiologic needs. Tidal volume is
an important component of pulmonary ventilation because it
represents the ordinary volume of air exchanged with each
breath.
Question 2
,______ is the movement of fluid to a tissue.
Correct Answer: Perfusion
Detailed Professional Rationale:
Perfusion refers to the delivery of blood to body tissues
through the circulatory system. Adequate perfusion provides
cells with oxygen and nutrients and facilitates removal of
metabolic waste. In the lungs, pulmonary perfusion refers to
blood flowing through capillaries surrounding the alveoli for
gas exchange.
Question 3
_______ is a term used to describe breathing or the
movement of air into and out of the lungs.
Correct Answer: Ventilation
Detailed Professional Rationale:
Ventilation is the movement of air into and out of the
respiratory tract. Inspiration moves air into the lungs, while
expiration moves air out. Effective ventilation brings oxygen-
containing air to the alveoli and removes carbon dioxide from
the body.
,Question 4
______ is the amount of air that remains in the lungs after
maximal exhalation.
Correct Answer: Residual volume
Detailed Professional Rationale:
Residual volume is the amount of air remaining in the lungs
after maximal forced expiration. This air cannot be voluntarily
expelled and helps keep the alveoli open, preventing complete
lung collapse. It differs from tidal volume, which represents
air exchanged during normal breathing.
Question 5
Which of the following blood vessels carries deoxygenated
blood from the heart to the lungs?
Correct Answer: Pulmonary artery
Detailed Professional Rationale:
The pulmonary arteries carry deoxygenated blood from the
right ventricle to the lungs. In the pulmonary capillaries,
carbon dioxide diffuses out of the blood and oxygen diffuses
into it. Pulmonary arteries are an important exception to the
, general rule that arteries carry oxygenated blood because
arteries are defined by carrying blood away from the heart.
Question 6
The ______ brings oxygenated blood back to the left
atrium from the lungs.
Correct Answer: Pulmonary vein
Detailed Professional Rationale:
The pulmonary veins transport oxygenated blood from the
lungs to the left atrium. After blood undergoes gas exchange
in the pulmonary capillaries, it becomes oxygen-rich and
returns to the heart through these veins. The left atrium then
passes the blood to the left ventricle for systemic circulation.
Question 7
_____ is responsible for carrying oxygenated blood from
the left ventricle to the rest of the body.
Correct Answer: Aorta
Detailed Professional Rationale:
The aorta is the largest artery in the body and receives
