Superior thoracic aperture
The insuflation, deflation of the lungs produces great variations of pressure in the torax. If those variations were produced in a cavity including abdominal organs, some processes wouldn't take place (or could at least be not functional)
Posterior thoracic.
lower cervical and upper thoracic region
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 spleen is found in the upper far left part of the abdomen to the stomach.
"The plueral cavity is in the upper thoracic region of the human body. In human anatomy, the pleural cavity encases the lungs and is surrounded by the rib cage and the thoracic vertebrae."
Your thoracic cavity starts from the upper margin of the thoracic vertebra to upper margin of the manubrium of the sternum. There is your diaphragm on the lower side.
Women's breasts are located on the anterior upper half of the thoracic cavity on either side of the midline.
The thoracic cavity is the upper part of the torso and contains organs like the lungs and heart, while the abdominal cavity is the lower part. These two parts are separated by the diaphragm.
The gallbladder is found in the abdominal cavity, also called the peritoneal cavity.its found in the abdominal cavity, in the rigth hypocondriach region.
The insuflation, deflation of the lungs produces great variations of pressure in the torax. If those variations were produced in a cavity including abdominal organs, some processes wouldn't take place (or could at least be not functional)
The Sternum
The liver is an internal organ which lies in the abdominal cavity of the body of animals. In humans, it is the largest glandular organ of the body, and generally weighs about 3 lb (1.35 kg).
HUMAN Your thoracic hole is a space in your chest that contains organs, veins, nerves and other significant body structures. It's partitioned into three primary parts: right pleural depression, left pleural hole and mediastinum. The five organs in your thoracic cavity are your heart, lungs, throat, windpipe and thymus. RAT Find the stomach, which is a layer of muscle that isolates the thoracic from the stomach hole. The heart is halfway situated in the thoracic depression. The two dull hued chambers at the top are the atria (single: chamber), and the base chambers are the ventricles. The heart is covered by a slim film called the pericardium. (We will return to the heart later.) Find the thymus organ, which lies straight over the upper piece of the heart. The thymus capabilities in the improvement of the safe framework and is a lot bigger in youthful rodents than it is in more established rodents. The lungs are supple organs that lie on one or the other side of the heart and ought to take up the vast majority of the thoracic hole. checkbox
Upper thoracic region
The diaphragm, a large dome-shaped muscle, lies just under the lungs. Its upward dome-shape flattens, moving downward and expanding the thoracic cavity, during inspiration. The rib muscles simultaneously contract and pull the rib cage up and outward, further expanding the thoracic cavity. The increased volume of the thoracic cavity causes air to rush into the lungs. Exhalation occurs when the diaphragm and rib muscles relax, reducing the volume of the thoracic cavity. The expansion and contraction of the thoracic cavity occurs between 12 and 20 times each minute in adults.
The organs that are in the thorax are the heart, lungs, thymus, trachea, bronchi, esophagus, and the thoracic duct. The paired vague nerves and the paired sympathetic chains are also included.
