What are the two main body cavities?
The cavities, or spaces, of the body contain the internal organs, or viscera. The two main cavities are called the ventral and dorsal cavities. The ventral is the larger cavity and is subdivided into two parts (thoracic and abdominopelvic cavities) by the diaphragm, a dome-shaped respiratory muscle.

What cavity contains the internal organs?
The abdominal cavity holds digestive organs and the kidneys, and the pelvic cavity holds reproductive organs and organs of excretion.
How many cavities are in the body?
In the dorsal body cavity the brain and spinal cord are located. The membranes that surround the central nervous system organs (the brain and the spinal cord, in the cranial and spinal cavities are the three meninges….
Body cavity FMA 85006 Anatomical terminology How is the human body divided into cavities?
The human body, like that of many other multicellular organisms, is divided into a number of body cavities. A body cavity is a fluid-filled space inside the body that holds and protects internal organs. Human body cavities are separated by membranes and other structures.
Which is the ventral cavity of the human body?
Thoracic cavity–the space occupied by the ventral internal organs superior to the diaphragm. Abdominopelvic cavity–the abdominal cavity and the pelvic cavity in combination.
What kind of organs are in the dorsal cavity?
The dorsal cavity includes the cranial and spinal cavities. Th e ventral cavity is a t the anterior, or front, of the trunk. Organs contained within this body cavity include the lungs, heart, stomach, intestines, and reproductive organs. You can see some of the organs in the ventral cavity in Figure 10.5.
Where are the thoracic cavities located in the body?
Ventral body cavity. The thoracic cavity consists of three cavities that fill the interior area of the chest. The two pleural cavities are situated on both sides of the body, anterior to the spine and lateral to the breastbone. The superior mediastinum is a wedge-shaped cavity located between the superior regions of the two thoracic cavities.
What are the different types of body cavities?
There are two main body cavities: the dorsal cavity and the ventral cavity. The dorsal or posterior cavity contains the cranial cavity and the spinal cavity.
What houses the dorsal cavity?
The dorsal body cavity is located along the dorsal (posterior) surface of the human body, where it is subdivided into the cranial cavity housing the brain and the spinal cavity housing the spinal cord. The two cavities are continuous with one another. The covering and protective membranes for the dorsal body cavity are the meninges.
What are the anatomical cavities?
Anatomical terminology. [edit on Wikidata] A body cavity is any space or compartment, or potential space in the animal body. Cavities accommodate organs and other structures; cavities as potential spaces contain fluid. The two largest human body cavities are the ventral body cavity, and the dorsal body cavity.
What are the parts of the dorsal cavity?
As seen in the image below, the dorsal cavity consists of two parts: the cranial cavity and the vertebral (spinal) cavity. The dorsal cavity starts with a membrane and the inside of the skull, traveling down through the spinal column as a protection for the spinal cord.
