Etymology
The term "cavity" comes from the Latin word "cavitas," which means "hollowness" or "hollow space." The term "human body" is self-explanatory, referring to the body of a human being.
Types of Body Cavities
There are two main types of body cavities in the human body:
- Dorsal Body Cavity: This cavity is located at the back of the body and is divided into two parts: the cranial cavity, which houses the brain, and the spinal cavity, which contains the spinal cord.
- Ventral Body Cavity: This cavity is located at the front of the body and is also divided into two main parts: the thoracic cavity, which contains the heart and lungs, and the abdominopelvic cavity, which houses the digestive organs, urinary system, and reproductive system.
