Salivary Glands and Functions

Professor Bob Long introduces a lecture on anatomy and physiology, focusing on the beginning of the digestive tract. He discusses the oral cavity, including the labia, teeth, tongue, and lingual frenulum. The lecture then covers the salivary glands, including the parotid, submandibular, and sublingual glands, and their respective ducts. Professor Long uses anatomical models to demonstrate these structures and explains their functions in digestion. The video concludes with a brief preview of the next topic, which will cover the teeth.
