Anatomy - Body Cavities & Serous Membranes

This video tutorial covers the major body cavities, including the dorsal and ventral cavities, and their subdivisions. It explains the cranial and vertebral cavities within the dorsal cavity, and the thoracic and abdominal pelvic cavities within the ventral cavity. The tutorial also introduces serous membranes, detailing their structure and function in the pleural, pericardial, and abdominal pelvic cavities. The video concludes with a recap of the key concepts discussed.
