Students label diagrams and answer thought-provoking questions about the frog’s anatomy and physiology. A student worksheet for completion during work.A set of step-by-step dissection procedures for a student-led frog dissection (One set for external structures, one set for internal structures).Please check the preview carefully to make sure it fits your curriculum. It is not meant to be a comprehensive or exhaustive exploration of anatomy and physiology. This is a basic introduction to vertebrate anatomy for general Biology classes. In the second part of the laboratory, students explore the internal anatomy of the frog. The first part includes external anatomy, which allows teachers to keep the frogs intact for the next class. This lab is specially designed to be completed in two class sessions. This one has everything you need: just add frogs! Includes lab directions, student worksheets, diagrams and pictures of frog anatomy, and discussion questions. Veins They take blood to the heart Lungs They are located to each side of the liver lobes Frog's Heart 1.Blood moves from the body to the right atrium.ģ.Blood moves to the lungs to get oxgenated.Ĥ.Blood moves from the lungs to the light atrium.Ah, the Biology frog dissection- a staple of any life science course. Arteries They take blood awat from the heart. Ventricle The low chambers that takes the blood to the lungs. Atrium Thes are the upper chambers of the heart which serve to collect blood returning to the heart from the body. Heart This the organ responsible for the pumping of the bood throughout an organism. Uterus This holds the fertilized eggs during the development. The kidney's function is to filter the blood. Kidneys in the Female They are two long reddish organs located one on either side of the backbone. Ovaries This is a gland in the female that produces estrogen and progesterone eggs are produced here. Oviducts This is are tubes that carry eggs. Bladder This is a sac that holds urine to be excreted. Testes This is where testosterone is produced. Kidneys in the Male This is where blood is filters and produces urine. Spleen This is a filtering devise for blood. A large section at the end of the small intestines just before the anus. Cloaca This si a common reproductive, excretory organ in the frog. Gallbladder This is where the bile is stored. Its function is to break down fats and oils. Bile This is a greenish liquid produced by the liver, stored in the gallbladder. Liver This is the largest organ of the body produces and stores many substances vital to the existence of the organism this also where bile is produced. Small Intestines This is where majority of digestion and aborsorption takes place in here Large Intestines This is the place where the aborbs thr remaining nutrients and what is left is soild waste. The pancreas produces several digestive enzymes. Pancreas This is a narrow band of whitish tissue found at the crook of the stomach. Stomach This breaks down food into a soupy mixture or chyme. Glottis This is the air passage to the lungs. Esophagus This is the tube that carries food to the stomach. Auditory Orifice This recognize and properly respond to the various calls of its own species. Its attachment in the front allows it to reach great lenghts. Tongue This is a fly-catching device in the frog. Vomerine Teeth These teeth are two knob-like, backward slanting teeth, located on the upper jaw of the frog these teeth capture the prey. Maxillary Teeth These are the teeth found on the maxillary bone or upper jaw these teeth hold the prey. Students start with the external anatomy and mouth, then explore the organs of the digestive, urinary, and reproductive systems. Internal Nostrils This helps the frog to smell. Frog Dissection Answer Key by Biologycorner 4.9 (34) 2.50 Word Document File Student dissection guide details how to examine the external and internal anatomy of the frog. Nictiting Membrane This is the covering over the eye in a frog this is similar to cornea in humans External Nostrils This is the opening through which the frog is able to breath air.
