Pericardium contains Heart and Pleura contains pair of Lungs. Heart contract and relax at the rate of 72/minute.(In exercise, heart rate may go up to 180/minute.) Lungs are made up of totally elastic tissue, which will contract to very small size ball if not kept expanded. Which also contract and relax at the rate of 12 to 15/minute and may increase up to 60/minute. So both of them are enclosed in a closed cavity, having two layers. ( You have two pleura, one for each lung.) These closed cavities contain little amount of fluid to lubricate and minimize the friction, during movement of these organs.
The thoracic cavity contains the pleural and pericardial cavities. The thoracic cavity is enclosed by the ribs, sternum, and vertebral column.
It's the medial part of the thoracic cavity which contains the heart.
The pericardium surrounds the heart. Pleural and peritoneal cavities would include the heart lungs and the intestines respectively
Middle mediastinum
thoracic cavity
The Abdomen. The trunk contains the Thoracic cavity {containing the Pleural & Pericardial cavities} in the upper 1/3 of the trunk. The lower 2/3 of the trunk contains the Abdomino-pelvic cavity {containing the Abdominal & Pelvic cavities}. The 'trunk' is the body minus the head, arms and legs.
The two main cavites are Thoracic (above the diaphragm) and the abdaminopelvic (below the diaphragm) Then those have cavieties in them the thoracic has the pleural cavities which there 2 of those one for each lung. then there is the the mediastinal cavity between the two peural cavities. then i believe the Mediastinal cavity contains the Pericardial cavity for the heart. sorry about the spelling. then the abdominopelvic is splitt into two sub cavities the abdominal and pelvic cavity. they may be more but those are the ones I know of The two main cavites are Thoracic (above the diaphragm) and the abdaminopelvic (below the diaphragm) Then those have cavieties in them the thoracic has the pleural cavities which there 2 of those one for each lung. then there is the the mediastinal cavity between the two peural cavities. then i believe the Mediastinal cavity contains the Pericardial cavity for the heart. sorry about the spelling. then the abdominopelvic is splitt into two sub cavities the abdominal and pelvic cavity. they may be more but those are the ones I know of
The pleural cavity is the potential space between the two pleura (visceral and parietal) of the lungs, the intraembryonic coelom is one continuous space. During development this space partitions to form the pericardial, pleural and peritoneal cavities. The diaphragm and the paired pleuropericardial membranes separate the coelomic cavity into four parts. From the splanchnopleura (the visceral mesodermal layer) develops the Visceral pleura and from the somatopleura (parietal mesodermal layer) develops the parietal pleura.
Orbital Cavity
I am answering with the assumption you are referring to the trunk/core of the body. The trunk contains the Thoracic cavity {containing the Pleural & Pericardial cavities} at the upper 1/3 of the trunk. The trunk contains the Abdominopelvic cavity {containing the Abdominal & Pelvic cavities} at the lower 2/3 of the trunk. {Based on the above mentioned thirds} I would say the "Center part of the body" would be the Abdominal cavity. Further, I would specify the Epigastric {and possibly Umbilical} region{s}.
The lungs
The thoracic cavity is the anatomical region with the lungs being situated inside the right and left pleural cavities that flank the pericardial cavity .
The pig's heart is located in the thoracic cavity. The thoracic cavity is divided into he pericardial cavity and two pleural cavities which house the lungs.
The Abdomen. The trunk contains the Thoracic cavity {containing the Pleural & Pericardial cavities} in the upper 1/3 of the trunk. The lower 2/3 of the trunk contains the Abdomino-pelvic cavity {containing the Abdominal & Pelvic cavities}. The 'trunk' is the body minus the head, arms and legs.
Pleural cavity is the potential space. There is no gap between the outer and the inner pleura. There is very little fluid in the pleural cavity. You have negative pressure in the pleural cavity.
The pleural cavities, ventral and thoracic
The two main cavites are Thoracic (above the diaphragm) and the abdaminopelvic (below the diaphragm) Then those have cavieties in them the thoracic has the pleural cavities which there 2 of those one for each lung. then there is the the mediastinal cavity between the two peural cavities. then i believe the Mediastinal cavity contains the Pericardial cavity for the heart. sorry about the spelling. then the abdominopelvic is splitt into two sub cavities the abdominal and pelvic cavity. they may be more but those are the ones I know of The two main cavites are Thoracic (above the diaphragm) and the abdaminopelvic (below the diaphragm) Then those have cavieties in them the thoracic has the pleural cavities which there 2 of those one for each lung. then there is the the mediastinal cavity between the two peural cavities. then i believe the Mediastinal cavity contains the Pericardial cavity for the heart. sorry about the spelling. then the abdominopelvic is splitt into two sub cavities the abdominal and pelvic cavity. they may be more but those are the ones I know of
CHEST CAVITY!!! =]
The ventral cavity is subdivided into 2 other cavities, the thoracic cavity and abdominopelvic cavity which are separated by the diaphragm. Some of the organs within each are:THORACIC2 pleural cavities > lungsmediastinum > pericardial cavity, major blood and lymph vesselspericardial cavity > heartABDOMINOPELVICabdominal cavity > stomach, liver, spleen, gallbladder, pancreas, small intestinepelvic cavity > urinary bladder, colon, rectum, reproductive organs
Viscera denotes the organs in the body cavities. (The heart confined in the Pericardial cavity, the lungs in the Pleural cavity, and the abdominal organs in the Peritoneal cavity). Visceral membrane (visceral serosa) covers those organs.
The ventral cavity is subdivided into 2 other cavities, the thoracic cavity and abdominopelvic cavity which are separated by the diaphragm.

It is in the thoracic cavity and it subdivides the pleural cavities
