Yes, the diaphragm lies between the thoracic and abdominal cavities and assists us to breathe.
The diaphragm supports the lungs inside the thoracic cavity. It is necessary for it to form a tight seal so that the lungs cannot be compromised.
diaphragm
The diaphragm is situated between the chest cavity and the abdominal cavity.
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 characteristics of a rats diaphragm is that it contracts and changes in size when the rat breathes. The diaphragm of the rat is found between the abdominal cavity and thoracic area. It appearance is long and thin looking.
The large dome-shaped muscle (not an organ) that separates the thoracic (chest) cavity from the abdominal cavity and aids in breathing is the diaphragm. Actually fibromuscular, the diaphragm is the main muscle that we use to inflate our lungs. It forms a partition between the two cavities, and creates a 'seal'. It allows the lungs to expand so we can take in and expel air. It is part of both the muscular and respiratory systems.
thoracic
The major muscle is called the diaphragm. It separates the thoracic and abdominal cavities. When it contracts, it moves downward, thereby increasing the volume of the thoracic cavity. In addition, the external intercostal muscles (between your ribs) will contract, and by doing that pull your ribcage outward and also increase volume.
thorax = the part of the human body between the neck and the diaphragm, partially encased by the ribs and containing the heart and lungs; the chest. diaphragm = a body partition of muscle and connective tissue separating the chest and the abdominal cavities.
The ascending aorta extends from the aortic root (which connects the aorta to the heart), upwards toward the aortic arch. The thoracic aorta is one of two parts of the descending aorta, which extends back down towards the abdomen after the aortic arch. The thoracic aorta is the part of the descending aorta that is above the diaphragm, while the abdominal aorta is below the diaphragm.
Muscles of Respiration: The main muscles of respiration are the Diaphragm, which forms the partition of the chest from the abdomen, and the abdominal muscles. Accessory muscles will also take part in helping with respiration during respiratory distress after severe exercise, respiratory obstruction, heart failure. The accessory muscles are, sternocleidomastoid, platysma, and the strap muscles of the neck.
