The thoracic cavity contains the ________. It is found ________ to the vertebral cavity.
Natasha_Volkova [10]

Answer: The thoracic cavity contains the heart, lungs and many of the main vessels of the circulatory system. It is found anterior to the vertebral cavity.

Explanation:

The thoracic cavity is the second largest hollow space of the body and it is the space limited by the ribs, the vertebral column, and the sternum. It is the upper region of the body starting from the neck and ending where the diaphragm ends. So, it is separated from the abdominal cavity by the diaphragm. It contains 12 ribs, and 7 of them attach directly to the sternum, 3 attach to the sternum via cartilages and 2 do not attach to the sternum at all and are called floating ribs. The cavity contains several organs, such as the lungs, heart, great vessels and esophagus.

The abdominal cavity spaces around the organs are filled with the core muscles that attach to the posterior spine. Besides. the ribs vertically, horizontally and across the abdominal region.

The vertebral cavity is the posterior portion of the dorsal cavity, it contains the spinal cord within the vertebral column, the meninges and the fluid-filled spaces between them. It is formed by the vertebrae through which the spinal cord passes.

<u>The thoracic cavity is anterior to the vertebral cavity, because anterior describes the front or direction toward the front of the body</u>.
