![]() ![]() They have two sets of teeth in the buccal cavity. Frogs don’t have strong teeth like humans. The tip of the tongue is folded backwards. The digestive process of frogs starts with ingestion, which involves catching their prey (flies, spiders, worms, slugs, other insects, and smaller animals that can fit into their mouth) with their sticky, cleft or bilobed tongue, and swallowing it. ![]() To get a better understanding of the location of the organs and functions of the digestive system, a labeled diagram of the digestive system of frogs has been provided below. These nutrients are absorbed into the bloodstream, and utilized by the cells and tissues of the body for carrying out the vital body processes. These organs work in tandem to digest or break down the ingested food into smaller molecules or nutrients, which are easier to absorb and assimilate. Accessory organs and glands such as the tongue, teeth, salivary glands, gastric glands, pancreas, liver, and gallbladder perform functions that are essential for the process of digestion. Like humans, the digestive system of frogs consists of the digestive tract, which in turn comprises organs such as the mouth, pharynx, esophagus, stomach, small intestine, large intestine, and cloaca. Their head contains the brain, mouth, eyes, ears, and nose. Referred to as coelom, this body cavity houses all the internal organs. Frogs have a single body cavity in the trunk. ![]() The anatomy of frogs has been of interest to humans due to the striking similarities in the organ systems of frogs and humans. The characteristic features of these amphibians include short bodies, the absence of tail, long hind legs that allow them to leap, webbed fingers and toes, and protruding eyes. The term Anura means ‘without tail’, and this taxonomic group comprises frogs and toads. This helps them push food down the throat.įrogs belong to Amphibia class and subphylum Vertebrata, which means that they are a class of vertebrates that live on land, but breed in water. After catching their prey, frogs close their eyes and retract them through the holes in their skull. ![]()
