What factors might alter the relationship between body mass, body temperature, and metabolic rate?Explanation / Answer
7) The glands associated with the digestive system are salivary glands, liver and pancreas. The salivary glands secrete saliva that are rich in enzymes amylase, ptyalin etc. They help in the process of digestion.
Liver is the most important organ for various metabolic processes that takes place in the body like glycogenolysis, gluconeogenesis, lipogenesis etc. Liver is the major storage organ of excess carbohydrates and fats. It secretes bile which helps in digestion of fats.
Pancreas secrete various enzymes like trypsin, chymotrypsin, carboxy peptidase etc. which help in digestion of proteins. They regulate carbohydrate metabolism by secreting the hormones insulin and glucagon.
Thus, glands play a major role in the process of digestion.
