The thoracic cavity contains the great vessels, heart and lungs, and some smaller structures.
To expose the contents of the chest cavity, we used a scalpel and made a transverse incision to the xiphoid process the sternum, to avoid cutting into the abdominal cavity. It also makes an incision caudal to the ribs attached to the sternum and ran down the right side of the ventral side of the chest to the left ventral thorax. Then two incisions were made from both sides (right and left), until it reached the clavicles. Finally, cut by the zone above the clavicles. The opening was made approximately 5 cm wide.

Lacrimal Gland Parotid Gland: A salivary gland located just below the ear
3-mandibular gland: Located ventral to the angle of the jaw
4-lymph nodes, they are part of the lymphatic system and are one of the sites where lymphocytes develop
5-Sublingual gland: salivary gland found below the tongue.

- After removing the left lung, we could see in dorsal aorta and esophagus
- in most mammals, in rat heart apex is oriented ventrally.
As
Before cutting the center to examine the anatomy, we had to first remove the fat from the pericardium. are lower in fat that surrounds the heart deep in the thymus, this is necessary to cushion and protect heart.
The left cranial vena cava receives the veins of the thorax and the azygos vein and travels ventral to the aortic arch and root of the lung to reach the right atrium. The circulation through the heart of rats is similar to that of any other mammal.

deoxygenated blood enters the right atrium through the cranial vena cava, the inferior vena cava, and left cranial vena cava. Once in the right atrium, deoxygenated blood flows into the right ventricle, and then goes through the pulmonary arteries to the lungs to be oxygenated. The new oxygenated blood from the lungs goes to the atrium through the left pulmonary veins. Of the left atrium, blood flows into the left ventricle and the aortic arch to be distributed to the body.
