Help control what passes between squamous epithelial cells and the alveoli b. Decrease the surface tension, therefore increase lung compliance c. Increase surface tension, therefore increase lung compliance d. Produce mucus and phagocytize bacteria in the upper respiratory system

Explanation / Answer

The first part that filter in glomerulus is the plasma, proteins are not filtered but retain in the plasma.

Glomerulus is atiny ball shaped structure compose of capillary blood vessels actively involve in the filtration of blood to form urine.

Hence the correct option is (c)
