Where does the thoracic cavity lies?
The thoracic cavity is the anterior ventral body cavity found within the rib cage in the torso. It houses the primary organs of the cardiovascular and respiratory systems, such as the heart and lungs, but also includes organs from other systems, such as the esophagus and the thymus gland.
What are the 3 major subdivisions of the ventral body 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.
What are the subdivisions of the cranial cavity?
Together the cranial cavity and spinal (or vertebral) cavity can be referred to as the dorsal body cavity. In the posterior (dorsal) cavity, the cranial cavity houses the brain, and the spinal cavity encloses the spinal cord.
Are the lungs in the thoracic cavity?
The chest (thoracic or pleural) cavity is a space that is enclosed by the spine, ribs, and sternum (breast bone) and is separated from the abdomen by the diaphragm. The chest cavity contains the heart, the thoracic aorta, lungs and esophagus (swallowing passage) among other important organs.
Which cavity is least protected?
abdominal cavity
The abdominal cavity provides the least protection to its structures. The cranial cavity protects the brain inside the skull, while the spinal cord…
What are the two major organs that occupy the thoracic cavity?
It contains the lungs, the middle and lower airways—the tracheobronchial tree—the heart, the vessels transporting blood between the heart and the lungs, the great arteries bringing blood from the heart out into general circulation, and the major veins into which the blood is collected for transport back to the heart.
What other cavities are located inside the thoracic cavity?
The thoracic cavity fills the chest and is subdivided into two pleural cavities and the pericardial cavity . The pleural cavities hold the lungs, and the pericardial cavity holds the heart. The pleural cavities hold the lungs, and the pericardial cavity holds the heart.
What are the major body cavities and their subdivisions?
The organs of the body lie mostly within two major cavities: the Ventral cavity and Dorsal cavity. The Dorsal cavity lies within the skull and vertebral column and has two subdivisions: the Cranial cavity and the Spinal cavity. As the names suggest, the cranial cavity hosts the brain and the spinal cord is found within the spinal cavity.
What organs is located within the thoracic cavity?
The diaphragm, lungs, trachea, and the bronchi are the main respiratory system organs in the thoracic cavity. Most of the digestive system organs are located in the abdominal cavity. However, the esophagus, the tube that carries food to the stomach is located in the thoracic cavity.
What are the 3 subdivisions of the ventral body cavity?
The ventral cavity is divided by the diaphragm, a thin dome-shaped sheet of muscle, into a superior thoracic cavity as well as an inferior abdominopelvic cavity. The thoracic cavity is guarded by the rib cage and contains the heart and lungs. The abdominopelvic cavity is subdivided into a superior abdominal cavity and an inferior pelvic cavity, however, there is no structural separation between them.
