[2] The thoracic cavity contains organs and tissues that function in the respiratory (lungs, bronchi, trachea, pleura), cardiovascular (heart, pericardium, great vesselsgreat vessels The great vessels may be injured by narrow impact (e.g., a horse kick) or wide impact (e.g., deceleration injury [Fig. 9]) blunt trauma.

, lymphatics), nervous (vagus nerve, sympathetic chain, phrenic nerve, recurrent laryngeal nerve), immune (thymus) and digestive (esophagus) systems.

What organs are part of 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 are the 3 parts of the thoracic cavity?

The thoracic cavity has three compartments: the mediastinum and two pleural cavities. The mediastinum is home to the heart, trachea, great vessels, and some other structures. The pleural cavities are on either side of the mediastinum and contain the lungs and the pleural linings.

What are the types of thoracic cavity?

There are two openings of the thoracic cavity, a superior thoracic aperture known as the thoracic inlet and a lower inferior thoracic aperture known as the thoracic outlet. The thoracic cavity includes the tendons as well as the cardiovascular system which could be damaged from injury to the back, spine or the neck.

Is the thoracic cavity dorsal or ventral?

The ventral cavity includes the thoracic and abdominopelvic cavities and their subdivisions. The dorsal cavity includes the cranial and spinal cavities.

What cavity is the lung in?

The chest cavity is the area surrounded by the thoracic vertebrae, the ribs, the sternum, and the diaphragm. The lungs are housed in the chest cavity, a space that also includes the mediastinum.

What are the four cavities that make up the thoracic cavity?

Thoracic Cavity and Organs

The Mammalian coelum is made up of 4 main parts; The Abdominal Cavity, Pericardial Cavity, and two Pleural Cavities. The Pericardial and Pleural Cavities along with the Mediastinum make up the Thoracic Cavity.

What is not part of the thoracic cavity?

In mammals, the thorax is the region of the body formed by the sternum, the thoracic vertebrae, and the ribs. It extends from the neck to the diaphragm, and does not include the upper limbs. The heart and the lungs reside in the thoracic cavity, as well as many blood vessels.

Which two cavities are found in the thoracic cavity?

Thoracic Cavity: The ventral body chamber that contains the pericardial cavity (the heart) and the pleural cavity (the lungs).

How many organs are in the thoracic cavity?

Thoracic cavity: The chest; contains the trachea, bronchi, lungs, esophagus, heart and great blood vessels, thymus gland, lymph nodes, and nerve,. as well as the following smaller cavities: Pleural cavities: Surround each lung. Pericardial cavity: Contains the heart.

What is the thoracic?

The spine in the upper back and abdomen is known as the thoracic spine. It is one of the three major sections of the spinal column. The thoracic spine sits between the cervical spine in the neck and the lumbar spine in the lower back. ... Together, the brain and spinal cord make up the central nervous system.

Is the liver in the thoracic cavity?

The liver also creates bile, which helps the stomach digest food through a cocktail of enzymes and acids. Both the liver and the stomach are located in the lower chest region under the thoracic diaphragm, a sheet of muscle at the bottom of the rib cage that separates the chest cavity from the abdominal cavity.

Is the diaphragm in the thoracic cavity?

The diaphragm is an upward curved, c-shaped structure of muscle and fibrous tissue that separates the thoracic cavity from the abdomen. The superior surface of the dome forms the floor of the thoracic cavity, and the inferior surface the roof of the abdominal cavity.

Is the mediastinum in the thoracic cavity?

The thoracic mediastinum is the compartment that runs the length of the thoracic cavity between the pleural sacs of the lungs. This compartment extends longitudinally from the thoracic inlet to the superior surface of the diaphragm.

What cavities are in the ventral cavity?

The anterior (ventral) cavity has two main subdivisions: the thoracic cavity and the abdominopelvic cavity (see [link]). The thoracic cavity is the more superior subdivision of the anterior cavity, and it is enclosed by the rib cage.

What 5 organs are found in the thoracic cavity of a rat?

THORACIC ORGANS

• Trachea.
• Heart (Ventricles)
• Right Lung.
• Diaphragm.

What cavity is the heart in?

The heart lies within the pericardial cavity, in the middle mediastinum. The pericardial cavity is similar in structure and function to the pleural cavity. The pericardium provides a friction-free surface for the heart to accommodate its sliding movements.

Which body cavity is included in the dorsal cavity?

Dorsal body cavity–the cranial cavity and the spinal cavity in combination. Cranial cavity–the space occupied by the brain, enclosed by the skull bones. Spinal cavity–the space occupied by the spinal cord enclosed by the vertebrae column making up the backbone. The spinal cavity is continuous with the cranial cavity.

What are the left and right portions of the thoracic cavity divided by?

The diaphragm slopes down to the costal and vertebral attachments, so the thoracic wall narrows rapidly inferiorly (29-39). The thoracic cavity is divided by the mediastinum. The heart is in the mediastinum, enclosed by the pericardium.

What are the names of the two main cavities of the body?

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 is thoracic wall?

The thoracic wall consists of a bony framework that is held together by twelve thoracic vertebrae posteriorly which give rise to ribs that encircle the lateral and anterior thoracic cavity. ... The vertical bone of the chest, the sternum, defines the anterior chest wall.

What is cavitation in chest xray?

Summary: A pulmonary cavity is a gas-filled area of the lung in the center of a nodule or area of consolidation and may be clinically observed by use of plain chest radiography or computed tomography.

What separates the thoracic cavity from the abdominal cavity?

The diaphragm is a thin dome-shaped muscle which separates the thoracic cavity (lungs and heart) from the abdominal cavity (intestines, stomach, liver, etc.).

Is the thymus in the thoracic cavity?

The mediastinum is a division of the thoracic cavity; it contains the heart, thymus gland, portions of the esophagus and trachea, and other structures. ... For clinical purposes it is traditionally divided into the anterior, middle, posterior, and superior regions.
