  • What is a body cavity?
    A body cavity is a hollow space within the body that houses and protects internal organs.
  • Name the two main body cavities.
    The two main body cavities are the dorsal cavity and the ventral cavity.
  • What does the dorsal cavity contain?
    The dorsal cavity contains the cranial cavity (brain) and the spinal cavity (spinal cord).
  • What are the subdivisions of the ventral cavity?
    The ventral cavity is subdivided into the thoracic cavity and the abdominopelvic cavity.
  • What organs are found in the thoracic cavity?
    The thoracic cavity contains the heart and lungs.
  • What separates the thoracic cavity from the abdominopelvic cavity?
    The diaphragm separates the thoracic cavity from the abdominopelvic cavity.
  • What organs are found in the abdominopelvic cavity?
    The abdominopelvic cavity contains digestive organs, kidneys, bladder, and reproductive organs.
  • What is the function of serous membranes in body cavities?
    Serous membranes line body cavities and secrete fluid to reduce friction between organs.
  • Name the serous membrane that lines the thoracic cavity.
    The pleura lines the thoracic cavity and covers the lungs.
  • What is the pericardium?
    The pericardium is the serous membrane that surrounds the heart.
  • What is the peritoneum?
    The peritoneum is the serous membrane lining the abdominopelvic cavity and covering abdominal organs.
  • Define the cranial cavity.
    The cranial cavity is the space within the skull that contains the brain.
  • Define the spinal cavity.
    The spinal cavity is the space within the vertebral column that contains the spinal cord.
  • What is the mediastinum?
    The mediastinum is the central compartment of the thoracic cavity containing the heart, trachea, and esophagus.
  • What is the difference between the dorsal and ventral cavities?
    The dorsal cavity primarily protects the nervous system, while the ventral cavity houses organs involved in respiration, digestion, and reproduction.
  • Why are body cavities important?
    Body cavities protect organs, allow organ movement, and provide space for growth and development.
  • What is the pelvic cavity?
    The pelvic cavity is the lower part of the abdominopelvic cavity containing the bladder, reproductive organs, and rectum.
  • What is the abdominal cavity?
    The abdominal cavity is the upper part of the abdominopelvic cavity containing digestive organs like the stomach and intestines.
  • How do body cavities contribute to homeostasis?
    By protecting organs and allowing them to function properly, body cavities help maintain internal stability or homeostasis.
