검증된 단계별 안내1
Understand the concept of body cavities: Body cavities are spaces within the body that house organs. They are lined with membranes and can contain serous cavities, which are fluid-filled spaces that reduce friction between moving organs.
Identify the main body cavities: The major body cavities are the dorsal cavity (which includes the cranial and spinal cavities) and the ventral cavity (which includes the thoracic and abdominopelvic cavities).
Focus on the ventral cavity: The ventral cavity is divided into the thoracic cavity and the abdominopelvic cavity. Each of these cavities can contain multiple serous cavities.
Examine the thoracic cavity: The thoracic cavity contains the pleural cavities (each surrounding a lung) and the pericardial cavity (surrounding the heart). These are examples of serous cavities within the thoracic cavity.
Consider the abdominopelvic cavity: This cavity contains the peritoneal cavity, which is a serous cavity that surrounds many of the abdominal organs. Thus, both the thoracic and abdominopelvic cavities contain multiple serous cavities.
