Dissection Procedure

1. Obtain a preserved frog specimen and place it on a dissection tray.
2. Using a scalpel, make a ventral incision along the midline of the frog’s body, from the chin to the cloaca.
3. Carefully open the body cavity and pin the skin flaps back to expose the internal organs.
4. Identify the major organs of the frog, including the brain, lungs, heart, liver, stomach, intestines, kidneys, and reproductive organs.
5. Observe the external and internal anatomy of each organ and note its function.
6. Clean up the dissection area and dispose of the frog specimen and dissection materials properly.

Anatomical Structures: Label The Diagram Frog Dissection

• Brain:Controls the frog’s nervous system, including its behavior, movement, and sensory perception.
• Lungs:Facilitate gas exchange between the frog’s bloodstream and the environment.
• Heart:Pumps blood throughout the frog’s body, delivering oxygen and nutrients to its cells.
• Liver:Processes nutrients from food and detoxifies the blood.
• Stomach:Digests food and prepares it for absorption in the intestines.
• Intestines:Absorb nutrients from food and produce waste products.
• Kidneys:Filter waste products from the blood and produce urine.
• Reproductive organs:Produce and store gametes, enabling the frog to reproduce.

Reproductive organs	External fertilization	Internal fertilization	Internal fertilization	External or internal fertilization

Educational Applications

• Frog dissection provides students with a hands-on experience in animal anatomy and physiology.
• It helps students understand the structure and function of different organs and systems in the body.
• Frog dissection can be integrated into science curricula to enhance students’ understanding of biology and evolution.
• It can also foster critical thinking, problem-solving, and observation skills.

Safety Precautions

• Wear gloves and safety glasses when dissecting a frog.
• Handle the dissection materials carefully and avoid touching your face or mouth.
• Use sharp instruments with caution and dispose of them properly.
• Clean up the dissection area thoroughly after use.
• Dispose of the frog specimen and dissection materials according to your institution’s guidelines.
