Скачать или смотреть Swallowing, Peristalsis and Chemical Digestion in Oral Cavity

📌 In this video, we explain the fascinating process of swallowing (deglutition) and its four phases – from the voluntary movement in the mouth to the involuntary reflexes of the pharynx and esophagus. You’ll also learn about peristalsis, the rhythmic muscular movement that pushes food through the digestive tract, and the chemical digestion in the oral cavity, where enzymes like salivary amylase start breaking down starch.

🔹 Topics Covered:
Steps of swallowing (oral preparatory, oral propulsive, pharyngeal, esophageal phases)
Peristalsis and its role in food movement
Chemical digestion in the mouth (role of saliva, salivary amylase, and bolus formation)
✨ This video is perfect for Class 9 Biology students (Federal Board/National Book Foundation) and for anyone wanting a clear understanding of the early stages of digestion.
