Frogs are vertebrates with specialised amphibian characteristics and behaviours. They provide a great model organism for a range of biological studies; including, evolution, behaviour, anatomy, and physiology. Dissection of preserved frogs is an established introductory activity into vertebrate anatomy and mature body systems.

Animals using toxic peptides and proteins for predation or defense typically depend on specialized morphological structures, like fangs, spines, or a stinger, for effective intoxication. Here we show that amphibian poisons instead incorporate their own molecular system for toxin delivery to attacking predators.

Accessory Organs: Glands and Organs That Facilitate the Process of Digestion

The digestive system of frog mainly includes the alimentary canal and the digestive glands. In the alimentary canal the processes of mastication, digestion and absorption take place, while the digestive glands secrete certain enzymes which bring about the digestion of the ingested food. The alimentary canal of the frog is essentially a coiled tube of varying diameter that extends from mouth to cloacal aperture. It consists of the mouth, buccal cavity, pharynx, oesophagus, stomach, intestine and cloaca. The alimentary canal starts with an aperture which is known as mouth opening. Mouth is a very wide gape bounded by upper and lower jaws covered by immovable lips.

Dissection Instructions

Food that is chewed in the oral cavity then swallowed ends up in the stomach where it is further digested so its nutrients can be absorbed in the small intestine. The salivary glands, liver and gall bladder, and the pancreas aid the processes of ingestion, digestion, and absorption. These accessory organs of digestion play key roles in the digestive process. Each of these organs either secretes or stores substances that pass through ducts into the alimentary canal. Six salivary glands, located around the oral cavity, secrete saliva. This substance moves out of the glands into the oral cavity through ducts.

The liver is the largest solid organ and the largest gland in the human body.
