In the glucose molecule, the chemical bonds between the. carbon (C) and hydrogen (H) atoms hold energy from the sun. 1. When our. bodies extract energy from food and convert it to a form that our cells can. use, we lose more than half of the total food energy as heat.
These secretions flow to the surface of the body or to the lining of a hollow structure in the body. The exocrine secretions are involved in many important functions, such as sweating, digestion and lubricating the eyes.There are many types of exocrine glands in the exocrine system.xamples include the salivary glands, liver, stomach, prostate, lacrimal glands, pancreas, sweat glands, sebaceous glands, and mammary glands. A few examples of conditions that afflict the exocrine system include infection, ulcer, cancer, tumors, obstruction, genetic conditions and sebaceous cysts.
Exocrine pancreas. The first function belongs to the exocrine pancreas. The pancreas produces digestive juices and enzymes to help digest fats and proteins. When food has been partially digested by the stomach, it is pushed into the duodenum (the first part of the small intestine).Secreting its enzymes into the duodenum helps to prevent the protein-digesting enzyme known as trypsin from eating the protein-based pancreas or its duct.he pancreas is a large organ approximately six inches long and is a key part of the digestive and endocrine systems. It is located deep within the upper abdomen, surrounded by the stomach, small intestine, liver and spleen. This organ is shaped like a pear, broad at one end and narrow at the other end.
