The liver and gallbladder are important to the digestion of a pig. These organs create and store bile which is a secretion that aids in the digestion of the pig.
Digestion
An example of secretion is the release of digestive enzymes by the pancreas into the small intestine to aid in the digestion of food.
There is no secretion or digestion in the esophagus. It is a muscular tube that connects the mouth to the stomach and serves as a passageway for food to travel down to the stomach through a process called peristalsis.
Gastric secretion is a normal and necessary process in the body that helps in digesting food. It involves the release of digestive enzymes and acids in the stomach to break down food and facilitate nutrient absorption. However, excessive gastric secretion or imbalances in the stomach acidity can lead to digestive issues like ulcers or acid reflux.
bile
Fats in chyme stimulate the secretion of bile from the gallbladder and enzymes from the pancreas to help with fat digestion and absorption in the small intestine.
the digestion of food is necessary for us to get energy
The purpose of secretion is to release substances, such as hormones or enzymes, from cells into the external environment or bloodstream for various physiological functions, like digestion, communication, and waste elimination.

Chemical digestion begins in the mouth with the secretion of saliva from three pairs of salivary glands. Saliva contains the digestive enzyme salivary amylase.
Mechanical Digestion (or physical digestion) is more about the mouth. It's chewing, biting, breaking down, and sofening the food. This is why its called "Mechanical" Digestion.Mechanical digestion involves the pulverizing and crushing of food particles, usually by chewing. Chemical digestion occurs through the secretion of digestive juices.
