The two largest body cavities are the ventral cavity and dorsal cavity. The ventral cavity is located in the front of the trunk and contains organs like the lungs, heart, stomach and intestines. It is subdivided into the thoracic cavity and abdominopelvic cavity. The thoracic cavity holds the lungs and heart. The abdominopelvic cavity contains the digestive organs, kidneys, and reproductive organs. The dorsal cavity is located in the back and is subdivided into the cranial cavity which holds the brain, and the spinal cavity which contains the spinal cord running down the length of the vertebral column.
