Question

LYMPH M 3. Several physical factors that influence the efficiency of pulm priely desc compliance, alveolar surface tension, and airway re factor and identify the one that is affecting Mikes resistance. Briefly describe each 4. What must happen to Mik e's intrapulmonary pressure in order for him to maintain normal asthma attacks? air flow during inhalation and exhalation when he is having one of his 5. How does Mike's body make the necessary changes in intrapulmonary pressure to maintain normal air flow when he is experiencing cold-induced asthma? 6. When Mike is experiencing an asthmatic attack, his forced vital capacity (FVC) is 6590, and his FEV1 is 65%. Are these values normal? Knowing how one performs FVC tests, explain these test results in Mike's case. (Assume that Mike and the doctor have performed an accurate test.) ake up ystem h s, the the ve to prey ck up l odstrea 7. Albuterol is a selective beta-2 adrenergic agonist, which means it specifically activates beta-2 adrenergic receptors on smooth muscle in the airways. How does this improve Mike's asthma?

Answer 1

Lungs are the part of respiratory system which is very elastin in nature. Due to its elastin property it help in inspiration. But in broncho - construction such as (asthma) lungs in need of more energy to get normal respiratory air. At the surface of alveoli it surface tension try to adhere and water molecules that are lining on the alveolar sacs. Thus the surface tension will lead to collapse the alveoli due to there are no surfactant found and breaks the surface tension. Airway resistance pulls it in to the air and flow it through respiratory tract and the resistance id responsible to increase the Mike's situation because of broncho - constriction
