Saliva produced per day is

Options

A. `1.0 dm ^(3)`
B. `1.5 dm ^(3)`
C. `2.0 dm ^(3)`
D. `2.5 dm ^(3)`

Answer

To determine the amount of saliva produced per day, we can follow these steps:

1. **Understanding Saliva**: Saliva is a colorless and sticky liquid produced by the salivary glands. It plays a crucial role in digestion, particularly in the breakdown of starches due to the presence of the enzyme salivary amylase.

2. **Role of Salivary Amylase**: Salivary amylase is an enzyme found in saliva that helps in the digestion of starch by converting it into simpler sugars like glucose.

3. **Daily Production of Saliva**: In a healthy human, the average amount of saliva produced daily is approximately 1.5 decimeters cubed (dm³).

4. **Choosing the Correct Option**: Given the options of 1 dm³, 1.5 dm³, 2 dm³, and 2.5 dm³, the correct answer based on the average daily production of saliva is 1.5 dm³.

Thus, the final answer is that the saliva produced per day is **1.5 decimeters cubed**.
