—The capacity of the cavity of the thorax does not correspond with its apparent size externally, because (1) the space enclosed by the lower ribs is occupied by some of the abdominal viscera; and (2) the cavity extends above the anterior parts of the first ribs into the neck.
The size of the thoracic cavity is constantly varying during life with the movements of the ribs and diaphragm, and with the degree of distention of the abdominal viscera.
From the collapsed state of the lungs as seen when the thorax is opened in the dead body, it would appear as if the viscera only partly filled the cavity, but during life there is no vacant space, that which is seen after death being filled up by the expanded lungs.

Thoracoscopy is an anterior transthoracic endoscopic approach to the thoracic cavity and mediastinum.
The cavity should be deep enough to expose the entire ventral surface of the dura across the spinal canal to the medial border of the contralateral pedicle (Fig.
Thoracic surgeons developed thoracoscopy as an alternative to thoracotomy to reduce the approach-related incidences of morbidity associated with the anterior transthoracic exposure.[1,8,11,12,15,17,18,20,23--25,30,31,33,39,42] In thoracoscopy (microsurgical endoscopy), small portal incisions in the intercostal spaces are used to access the thoracic cavity without retracting the ribs or widely separating the superficial tissues of the thorax.

 The Thoracic Diaphram   (Site not responding. Last check: 2007-11-06)
The thoracic diaphragm is a dome-shaped musculotendinous partition between the thoracic and abdominal cavities.
The descent of the domes increases the vertical diameter of the thoracic cavity.
As the diaphragm descends, the intra-thoracic pressure is decreased and the intra-abdominal pressure is increased.

 thoracic cavity --  Encyclopædia Britannica
It is enclosed by the ribs, the vertebral column, and the sternum, or breastbone, and is separated from the abdominal cavity (the body's largest hollow space) by a muscular and membranous partition, the diaphragm.
They are typically bled (a process called sticking or exsanguination) by the insertion of a knife into the thoracic cavity and severance of the carotid artery and jugular vein.
In human anatomy, the abdomen is a large cavity extending from the diaphragm above to the pelvic cavity below, and from the spine in the back to the wall of abdominal muscles in the front.

Except in the case of emergency procedures, candidates for general thoracic surgery should undergo a complete medical history and thorough physical examination prior to surgery.
Respiratory failure, hemorrhage, nerve injury, heart attack, stroke, embolism, and infection are all possible complications of general thoracic surgery.

In this case, the cause of the death is the compression that the thymic mass exercises on the respiratory movements.
At the level of the median wall, in proximity of the hilum of the lung, the pleura is reflected and covers the inner wall of the thoracic cavity and then becomes the parietal pleura.

 "Packing" of the Thoracic Cavity - A Technique to Treat Uncontrollable Intrathoracic Bleeding   (Site not responding. Last check: 2007-11-06)
This massive hemorrhage was the result of severe thoracic trauma in three cases, and in one case, the result of an injury caused by a failed transthoracic puncture.
After "packing" the thoracic cavity, the "towels" were removed three days later.
Therefore, we regard our method as a new useful way to treat massive hemorrhage within the thorax, when other treatment fails, no specialist is near by, or when there is a large number of patients with thoracic injuries during catastrophes.

 Thoracic cavity - Wikipedia, the free encyclopedia
The thoracic cavity is the chamber of the human body (and other animal bodies) that is protected by the thoracic wall (thoracic cage and associated skin, muscle, and fascia).
It contains the potential space called the pleural cavity and the mediastinum.
If the thoracic cavity is breached from the outside, as by a bullet wound or knife wound, a pneumothorax, or air in the cavity, usually results, often leading to one or both lungs collapsing and requiring immediate medical attention.

 Thoracic Surgery Division
The Thoracic Surgery Division at the University of Maryland Medical Center is nationally recognized for developing innovative treatments for disorders of the structures and organs of the chest, particularly the lungs and esophagus.
The Division offers surgical management for a variety of conditions that affect the lungs and thoracic cavity -- including lung and esophageal cancer -- using minimally invasive approaches whenever possible.
Faculty of the Thoracic Surgery Division also staff the Thoracic Oncology Program of the University of Maryland Greenebaum Cancer Center, where they use a new technique called thoracoscopic surgical staging and other innovative surgical procedures to evaluate and treat cancers of the lung and esophagus.

Contraction of the diaphragm enlarges the thoracic cavity, thereby decreasing pressure in the thoracic cavity so that it is less than the atmospheric pressure outside; air flows from the region of higer pressure (outside) through the mouth, nose, trachea....
and into the alveoli of the lungs inside the thoracic cavity where the pressure is lower.
Exhalation can be entirely passive: just stop contracting the muscles of inspiration and the thoracic cavity becomes smaller...and air flows out of the lungs and into the environment.
