Why Do We Have Saliva?

The video explains the constant presence of saliva in our mouths and its crucial roles. Saliva, produced by salivary glands, helps us talk, taste, and digest food. It keeps our mouths wet, aids in moving food, and enhances taste by dissolving flavors. Saliva contains enzymes that start breaking down food, like bread and potatoes, before it reaches the stomach, aiding digestion and energy absorption. The video concludes by highlighting saliva's importance and its various functions.
