The ventral body cavity is a hollow space at the front part of the human body. It houses viscera, which are bodily organs. The ventral body cavity is opposed by the dorsal body cavity, which is at the back of the body. The ventral and dorsal body cavities are the two main cavities of the human body.Two body cavities join together to form the ventral body cavity. They are the thoracic cavity, which is in the chest region, and the abdominopelvic cavity, which is in the abdominal and pelvic regions.he upper abdominal part of the ventral body cavity, or the abdominal cavity, is enclosed by the lower part of the ribcage. The stomach, intestines, liver, pancreas, gallbladder and kidneys are in the abdominal cavity, as are the ureters, which are tubes that connect the kidneys to the bladder.
