GROSS ANATOMY

Detailed explanation-1: -The thoracic cavity is divided by the mediastinum. The heart is in the mediastinum, enclosed by the pericardium. The lungs occupy the left-right regions and the pleura lines the corresponding half of the thorax and forms the lateral mediastinal boundary.

Detailed explanation-2: -Thoracic Cavity and Organs The Pericardial and Pleural Cavities along with the Mediastinum make up the Thoracic Cavity. The boundaries of the Thoracic Cavity are the Ribs (and Sternum), Vertebral Column, and the Diaphragm. The Diaphragm seperates the Thoracic Cavity from the Abdominal Cavity.

Detailed explanation-3: -Overview. The heart and lungs are located in the thorax, or chest cavity. The heart pumps blood from the body to the lungs, where the blood is oxygenated.

Detailed explanation-4: -thoracic cavity, also called chest cavity, the second largest hollow space of the body. 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.

Detailed explanation-5: -[2] The thoracic cavity contains organs and tissues that function in the respiratory (lungs, bronchi, trachea, pleura), cardiovascular (heart, pericardium, great vessels, lymphatics), nervous (vagus nerve, sympathetic chain, phrenic nerve, recurrent laryngeal nerve), immune (thymus) and digestive (esophagus) systems.
