Once the bolus enters the stomach, there is regulated release of a variety of enzymes that facilitate chemical digestion. Some of these enzymes also stimulate the accessory digestive organs to release their enzymes to aid in digestion. In addition to chemical digestion (particularly of proteins), the stomach also functions as: Bile also contains bilirubin, a yellow-orange pigment released by red blood cells as they break down. Your body can’t metabolize bilirubin on its own, so it relies on bacteria to help out. When the bacteria in your small intestine chow down on bilirubin, they produce a dark material called sterobilin. This by product gives stool it’s notable brown color. Chemical Digestion: The food then enters the stomach, where it is acted upon by gastric juices containing enzymes that break down proteins. The acidic environment of the stomach also helps in killing harmful bacteria. The presence of a digestive enzyme, known as amylase, in saliva allows chemical digestion of starches to begin. Digestion – breaking the large into the small Microbes that reside in the large intestine make a meal of the leftovers from the small intestine. As they interact with stool, gas is created. The smell associated with stool comes from the gases released during the break down of solid waste by bacteria.

Transportation: The lubrication provided by the mucus secreted by the mucous glands in the buccal cavity aids in the smooth passage of food. The food is then pushed towards the pharynx, aided by the inward bulging of the eye orbits during swallowing.

Small Intestine

When your digestive system runs smoothly, you feel healthy and comfortable. There are simple ways to keep your tummy in tip top shape. Secretes insulin when sugar levels are high, secretes glucagon when sugar levels are low, secretes pancreatic juice (tripsinogen, chymotripsinogen, elastase, amilase etc.) into the duodenum where it digests the chyme Main functions: detoxication of metabolytes, synthesis of proteins, production of biochemicals needed for digestion -> regulation of body's metabolism and energy storage

These features work in concert to ensure that the frog can efficiently capture, ingest, digest, absorb nutrients from, and finally expel the remains of its food. Alimentary CanalIn summary, the alimentary canal of a frog is a specialized system designed for the efficient processing of food. Each section, from the buccal cavity to the cloaca, plays a vital role in the frog’s overall digestion and nutrient absorption. This sequential and detailed explanation underscores the importance of each part of the alimentary canal in maintaining the frog’s digestive health. Within the abdominal cavity, the esophagus enters the stomach. This is a dilated area of the alimentary canal that participates in both mechanical and chemical digestion. It is divided into four main parts, namely the:
