The thoracic cavity is the space within the thoracic region that contains the heart, lungs, and other vital organs. Both terms are related to the same anatomical area and are often used interchangeably.

The question is asking for the correct answer between "Abdominal cavity" and "Abdominal". The correct answer is "Abdominal cavity" because it refers to the space within the abdomen that contains various organs such as the stomach, liver, and intestines. "Abdominal" alone is not specific enough and could refer to anything related to the abdomen, whereas "Abdominal cavity" specifically refers to the internal space within the abdomen.

The term "dorsal" refers to the back or upper side of an organism. It is often used to describe the location or position of certain structures or body parts.

Therefore, "dorsal" and "dorsal cavity" are related terminologies that pertain to the back or upper side of an organism and the body cavity located in that region.

The diaphragm is a dome-shaped muscle that separates the chest cavity from the abdominal cavity. The diaphragm cavity refers to the space enclosed by the diaphragm.

The diaphragm also aids in other bodily functions such as digestion and maintaining proper posture.
