Question

Quizplus · Accepted Answer

[IV A 2 a; Table 6.2]. Saliva is characterized by hypotonicity and a high $\mathrm{HCO}_{3}{ }^{-}$concentration (relative to plasma) and by the presence of $\alpha$-amylase and lingual lipase (not proteases). The high $\mathrm{HCO}_{3}{ }^{-}$concentration is achieved by secretion of $\mathrm{HCO}_{3}{ }^{-}$ into saliva by the ductal cells (not reabsorption of $\mathrm{HCO}_{3}^{-}$). Because control of saliva production is parasympathetic, it is abolished by vagotomy.

Which of the Following Is Characteristic of Saliva? A) Hypotonicity HCO3−\mathrm{HCO}_{3}{ }^{-}HCO3​−
