Study Guide Exam 2 The walls of the alveoli are composed of two tvnes of cells ivne land type II alveolar cells. The function of type II alveolar cells is to A) secrete surfactant B) trap dust and other debris C) replace mucus in the alveoli D) protect the lungs from bacterial invasion 10) Inflammation A is caused by bacterial activity to enhance the spread of disease B) is caused by viral activity to enhance the spread of the disease C) slows the healing process with swelling that can impair bodily function D) brings more leukocytes to the sight of infection

Answer 1

9. The function of the type II alveolar cells is to secrete a lipoprotein based surfactant material, to reduce the alveolar surface tension. Hence option A is correct.

10. Inflammation is the defensive response of the body, which is mediated by various chemical mediators in the body. It involves the migration of more leukocytes at the site of infection, this is called chemotaxis. Hence option D is correct.
