(B) The secretion of salivary glands is called saliva. The medium of saliva is slightly acidic. The quantity of saliva produced in an adult is $1000-1500 \; mL$ per day. Chemically,saliva is a mixture of water and electrolytes $(Na^+, K^+, Cl^-, HCO_3^-)$. Additionally,enzymes like salivary amylase (ptyalin) and lysozyme (an anti-bacterial agent) are also found in saliva,along with mucus which helps in lubricating the food.
