Explain the Heat loss and Bacteriolytic action
Heat loss - This is found in dog, sheep etc. Who do not have sweat glands? In very hot climate, they secrete more saliva (panting) causing greater heat loss.
Bacteriolytic action: Saliva contains lysozyme. It destroys cell walls of many bacteria.
Having looked at the functions of saliva, let us also get to know how the saliva secretion is controlled.
