What are the two major body cavities and their subdivisions?
The two largest human body cavities are the ventral cavity and dorsal cavity. The ventral cavity is at the anterior (or front) of the trunk. It is subdivided into the thoracic cavity and abdominopelvic cavity. The dorsal cavity is at the posterior (or back) of the body, and includes the head and the back of the trunk.
What are the 2 cavities?
The two largest human body cavities are the ventral cavity and the dorsal cavity. These two body cavities are subdivided into smaller body cavities. Both the dorsal and ventral cavities and their subdivisions are shown in Figure 10.5.
What are the 2 main functions of body cavities?
The body cavities house and protect the internal organs. 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 are the main body cavities?
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 are the major cavities of the human body?
1 Cranial cavity. Housing the brain and the pituitary glad. 2 Spinal cavity. Housing the spinal cord. 3 Thoracic cavity. Housing the lungs. 4 Abdominal cavity. Housing the major digestive organs. 5 Pelvic cavity. Housing the urinary and reproductive organs.
What makes up the anterior cavity of the human body?
The cranial cavity houses and protects the brain, while the spinal cavity houses and protects the spinal cord. The ventral or anterior cavity is separated into the thoracic cavity and abdominopelvic cavity. The thoracic cavity contains the heart and lungs.
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.
Is the spinal cavity part of the cranial cavity?
Information. The spinal cavity is continuous with the cranial cavity. Ventral body cavity–the thoracic cavity, the abdominal cavity, and the pelvic cavity in combination. Thoracic cavity–the space occupied by the ventral internal organs superior to the diaphragm.
