Frog Anatomy and Physiology Concepts

Mrs. Smith provides a comprehensive pre-lab guide for frog dissection, covering classification, anatomy, and the digestive, circulatory, and reproductive systems. The video also highlights unique features like the nictitating membrane and tympanic membrane, preparing students for hands-on dissection.
