Exploring Frog Internal Anatomy in Dissection

This video tutorial continues the dissection of a frog, focusing on its internal anatomy. It covers the process of making incisions to expose the internal organs, including the digestive, circulatory, respiratory, and excretory systems. The tutorial provides detailed steps for cutting through the skin and muscle tissue, identifying key organs like the liver and gallbladder, and tracing the path of the digestive system. The video concludes with a preview of the next lab, which will explore the frog's respiratory, circulatory, and excretory systems.

What is the first type of incision made during the frog dissection?

• Transverse incision

• Lateral incision

• Medial incision

• Anterior incision

Which tool is used to make the initial incisions in the frog's body?

What is the primary role of the frog's liver mentioned in the dissection?

• To store bile

• To circulate blood

• To produce hormones and enzymes

• To digest food

Where does digestion continue after the stomach in the frog?

• Large intestine

• Liver

• Small intestine

• Esophagus

What is the function of the pyloric sphincter in the frog's digestive system?

• To absorb nutrients

• To produce digestive enzymes

• To connect the stomach to the esophagus

• To close off the end of the stomach

What does the frog use its sticky tongue for?

• To capture prey

• To produce sound

• To breathe
