Functional Anatomy is part of the The Respiratory System section of Physiology. Practise 10 exam-style MCQs for NEET PG, FMGE, INI-CET and NEET SS, each with the correct answer and a detailed explanation.
Anatomic dead space by Fowler's single-breath method, the resistance profile of the bronchial tree and maximum voluntary ventilation anchor these Functional Anatomy MCQs, which test respiratory mechanics as high-yield NEET PG practice.
Sample Functional Anatomy MCQs with answers
Sample MCQ #1
Measurement of anatomical dead space is done by
AHelium dilution method
BSpirometer
CSingle breath N2 washout method
DXenon-Scan
Show Answer & Explanation ▾
✓ Correct Answer: C. Single breath N2 washout method
Anatomic dead space Is the volume of air present in the conducting zone (first 16 generations) which are not used for gas exchange Volume of anatomic dead space (ml) is approximately equal to the body weight in pounds. For a 70 kg man (154 pounds) it is 154 ml It is usually measured by Single breath N 2 washout method Reference: Ganong, 25th edition page no.632
Sample MCQ #2
Regarding Dead space volume in a normal individual
AAnatomical dead space > Physiological dead space
BAnatomical dead space = Physiological dead space
CAnatomical dead space < Physiological dead space
DAnatomical dead space is not related to physiological dead space
Show Answer & Explanation ▾
✓ Correct Answer: B. Anatomical dead space = Physiological dead space
In healthy individuals, Physiologic dead space roughly equals anatomic dead space Reference: Ganong, 25th edition page no.630
Sample MCQ #3
How will you calculate that how much inspired air actually ventilates the alveoli
ASingle breath N2 method
BDalton's law
CBohr equation
DBoyle's law
Show Answer & Explanation ▾
✓ Correct Answer: A. Single breath N2 method
The technique useful for measuring anatomic dead space single – breath Nitrogen method This method is also called Fowler's method Reference: Ganong, 25 th edition page no.630
Sample MCQ #4
Which among the following has the highest airway resistance?
ASmall sized bronchioles
BRespiratory bronchioles
CAlveolar duct
DBronchus
Show Answer & Explanation ▾
✓ Correct Answer: D. Bronchus
Bronchus has the highest airway resistance. The greatest amount of resistance to airflow occurs not in the tiny air passages of the terminal bronchioles but in some of the larger bronchioles and bronchi near the trachea. The reason for this high resistance is that there are relatively few of these larger bronchi in comparison with the approximately 65,000 parallel terminal bronchioles, through each of which only a minute amount of air must pass.
Sample MCQ #5
Maximum voluntary ventilation is
A25 L/min
B50 L/min
C100 L/min
D150 L/min
Show Answer & Explanation ▾
✓ Correct Answer: D. 150 L/min
Maximum Voluntary Ventilation (MVV) MVV is the largest volume of air an individual breath in and out of the lungs in 1 minute It is usually measured for 10-15 seconds and extrapolated for 1 minute Normal MVV is 120-170 L/min Reference: Ganong 25th edition/p
