Question

Surfactant
(a) is a protein produced by type II alveolar cells
(b) is excessive in many premature infants resulting
in difficulties in breathing
decreases the surface tension of the fluid lining
the alveoli
(d) is lacking in individuals suffering from acute
respiratory distress syndrome.​

Answer 1

OVERVIEW OF SURFACTANT. Pulmonary surfactant is a complex mixture of phospholipids (PL) and proteins (SP) that reduce surface tension at the air-liquid interface of the alveolus, thus preventing its collapse during end-exhalation [1,2]. ... Surfactant increases surface pressure while lowering surface tension

c is correct
