Using your own words, how would you explain the concepts in the following graphs/ figures to a Grade 4 pupil? Figure A. Relationships of the different variables of Volume and Capacities in the LungThorax system Figure B. (A) Airway resistance for each bronchus generation, and (B) total airway resistance vs. lung volume

Which of the following functions of the laryngeal muscles is innervated by the external laryngeal nerve? 1.   abduction of the vocal cords 2.   adduction of the vocal cords 3.   decreasing the pitch of the voice 4.   increasing the pitch of the voice Choose the following: (A) 1 and 2 (B) 3 and 4 (C) 4 only (D) 2 and 3 (E) 2, 3, and 4

Count how many times you breathe every minute, called your normal respiratory rate, in   respirations/minute: ___________ (note – use this number for calculations on p. 5, question 1) Although you cannot measure your lung volumes without the proper equipment, below are results from a typical student (& a female lab partner) that you can use as your own:   Value measured Trial 1 Trial 2 Trial 3   Tidal Volume (TV) (ml) portable           spirometer      (your data) 400 350 450 Average TV is Total/3 = Vital Capacity (VC) (ml)  portable         spirometer     (your data!) 3200 3700 3500 Highest Value = Vital Capacity (VC) (ml)  portable spir. (female partner’s data) 2900 3200 3400 Highest Value =

Prior to begin training for a marathon, you have some lung function tests performed. Your measured tidal volume at rest is 550 mL, your dead space volume is 150 mL, and your resting breathing rate is 12 breaths per minute. On a treadmill, your tidal volume increases to 1150 mL and your breathing rate increases to 30 breaths per minute. What is your alveolar ventilation rate when you are on the treadmill? O 30 Liters/min O 4.8 Liters/min O 12 Liters/min O 34.5 Liters/min O 6.6 Liters/min

Identify the incorrect statemnt about lung volumes  (A) upon maximal exhalation, the tidal volume, expiratory reserve volume, and residual volume are exhaled from the lungs  (B) tidal inhalation is the non forced inspiration of air into the lungs  (C) lung volumes is especially ddependent on height  (D)  the vital capacity is from the peak of inspiratory reserve volume to the peak of expiratory reserve volume

Total lung capacity is : the same as tidal volume the sum of vital capacity and residual volume the sum of inspiratory reserve and expiratory reserve volumes approximately 150ml in an adult

A 6-year-old child inhales a peanut while playing which lodged in his right bronchus. The part of the lung being ventilated by the right bronchus will be showing which of the following regarding V/Q situation. High V/Q rationormalLow V/Q ratioDead spacevasodilation
