The Taxonomy of a Frog Essay

By dissecting a frog, one can observe the many systems that enable a frog to function like many other organisms. The systems that were analyzed through dissection were the epidermis, muscles, digestive, urogential, circulatory, and respiratory system. All systems, including the skeletal, and nervous system, were compared to organisms rudimentary and advanced to the frog. The life cycle and taxonomy of a frog were also researched during this lab. Through frog dissection, an individual may expand their knowledge of multiple body systems in organisms like their own. The systems observed from the dissected frog were compared to a fish and a human. The first system analyzed was the epidermis of a frog, which is used for respiratory functions…show more content…
The heart’s circulatory system of a frog consists of three chambers, the left and right atrium, and a ventricle. The right atrium receives deoxygenated blood from the body, and the left atrium receives oxygenated blood from the lungs and skin. Both atria then go through a ventricle that does not allow the blood to mix. After the ventricle arranges the blood through capillaries, the separated blood goes to its location, either through pulmonary, carotid, or systemic arteries. In a human there are four chambers of the heart. Instead of one ventricle there are two. The left ventricle carries oxygenated blood to the body while the right ventricle carries deoxygenated blood to the lungs. A fish has a closed- loop, two chambered system which allows blood to enter into an atrium. Through a muscular ventricle structure, capillaries separate the deoxygenated, and oxygenated which then sends the blood to its destination through veins. Each organism compared does however send deoxygenated blood to the respiratory system and oxygenated blood to body organs in the digestive system. Between human and frog the stomach, pancreas, liver, small and large intestine serve the same purposes. The main differences are found in small and large intestine, and mouth. In the frog, the small intestine does not contain villi, and the large intestine disposes of both fluid, and liquid waste. During indigestion, frogs use their tongue to hold, and swallow their prey by pushing it back with
