It’s crucial to note that bile, while essential, does not contain digestive enzymes. Its primary function is to emulsify fats, making the liver a non-digestive organ in a strict sense. The mouth is the beginning of the digestive system, and, in fact, digestion starts here before you even take the first bite of a meal. The smell of food triggers the salivary glands in your mouth to secrete saliva, causing your mouth to water. When you actually taste the food, saliva increases. Stool is the solid waste of the digestive process. Believe it or not, your body doesn’t use every particle of food you ingest. Roughage (fiber) travels through the digestive system relatively intact. This is because the digestive enzymes produced in the body cannot break down fiber. The force that propels food and drink through the esophagus is called peristalsis. The smooth muscles that line the esophagus undergo regular contractions after a bolus is swallowed. The wave-like movement created by peristalsis continues throughout the digestive tract. The motion pushes food through all phases of digestion, in the stomach, small intestine, and large intestine.

Size and Shape: The buccal cavity of a frog is large, wide, and shallow, allowing it to accommodate and capture sizable prey.A storage point, which gradually releases its contents into the small intestines, to allow adequate time for further digestion and absorption.

The layers present in the gastrointestinal system are mucous membrane (mucosa), submucosa, muscularis externa, and serosa or adventitia. The mucosa and submucosa projections enhance the surface area available for absorption. The lamina propria and submucosa possess glands.The stomach is a dynamic organ, too. It churns, squeezes, and grinds boluses of food and mixes them with gastric secretions. Peristalsis continues in the stomach and is the driving force for blending food with stomach acid. Stomach secretions help make nutrients available for absorption later in the small intestine. It includes different organs such as the stomach and intestine. It aids in the digestion of meals and the absorption of nutrients from food. Bile is critical in the digestion of fats into free fatty acids. Bile is composed of water, salts, acids, and lipids. It is a medium in which fats and fat-soluble vitamins can dissolve and be carried into the blood stream via the villi.
