BIOD 151 -Essential Lab Human Anatomy & Physiology notebookcalculator font Exam Page 2 Answer the following five questions: Define the respiratory cycle. If someone inhales 500 mL. of air, 350 mL. will make it to the alveoli. That same person has a resting respiratory rate of 14 breaths per minute. What is the alveolar ventilation rate (AVR True or False: Resting exhalation is an active process. Define what a restrictive lung disorder is and give an example. Emphysema is considered to be which type of respiratory disease? a. Restrictive b. Obstructive c. a. and b. BACKNEXT REPORTAExplanation / Answer
1--Respiratory cycle
the event that occurs during one breath which means that inhalation + exhalation = 1 respiratory cycle, the event that occurs to inhale the air into the lungs, when diaphragm contracts to expand the thoracic cage and decrease the pressure inside of the chest
2--alveolar ventilation rate
the formula for calculating alveolar ventilation rate is =(tidal volume-dead space volume)*respiratory rate
so AVR=(0.5-0.15)*14
=0.350*14
AVR =4.9/min
3--false
Resting exhalation is a passive process in this process only diaphragm and external intercostals are mainly involved.
4--Restrictive lung disease or restrictive ventilation defect are a category of extrapulmonary, plural or parenchymal respiratory disease that restrict lung expansion resulting in a decrease lung volume or an increased work of breathing and inadequate ventilation or oxygenation.
example-Idiopathic pulmonary Fibrosis, sarcoidosis, hypoventilation syndrome, scoliosis, amyotrophic lateral sclerosis(ALS).
