If you are about to dissect a frog, this time we have collected for you a handful diagrams of a frog as the references! Frogs are amphibians, living both on land and in water. Their anatomy is very unique. Their bodies are similar to humans in that they have skin, bones, muscles, and organs. The frog’s body is supported and protected by a bony framework called the skeleton. It can be divided into a head, a short neck, and a trunk. On the outside of the frog’s head are two external nares, or nostrils; two tympani, or eardrums; and two eyes, each of which has three lids. The third lid, called the nictitating membrane, is transparent. Inside the mouth are two internal nares, or openings into the nostrils; two vomerine teeth in the middle of the roof of the mouth; and two maxillary teeth at the sides of the mouth. Also inside the mouth behind the tongue is the pharynx, or throat. You can see all those details in the following diagrams!
In the pharynx, there are several openings: one into the esophagus, the tube into which food is swallowed; one into the glottis, through which air enters the larynx, or voice box; and two into the Eustachian tubes, which connect the pharynx to the ear. The digestive system consists of the organs of the digestive tract, or food tube, and the digestive glands. From the esophagus, swallowed food moves into the stomach and then into the small intestine. Look at the following diagrams for further explanation.
Frogs breathe through their skin when underwater. Oxygen in the water can pass through their porous skin and go directly to the blood. They also have a pair of lungs that allow them to breathe when on land.The urinary system consists of the frog’s kidneys, ureters, bladder, and cloaca. The central nervous system of the frog consists of the brain, which is enclosed in the skull, and the spinal cord, which is enclosed in the backbone.
All these images of frog anatomy will surely help you in your biology projects. All diagrams are free to be saved.
