The pericardial cavity contains the heart, the muscular pump that drives the blood around the cardiovascular system. To expose the pericardial cavity, continue the incision into the pleuroperitoneal cavity forward through the coracoid bar and the hypobranchial musculature.

What does pericardial cavity consist of?
The pericardial cavity is the potential space formed between the two layers of serous pericardium around the heart. Normally, it contains a small amount of serous fluid that acts to reduce surface tension and lubricate. Therefore, the cavity facilitates the free movement of the heart.
What are the organs found in the thoracic cavity?
 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.
What is the function of the pericardial cavity?
The two layers of serous pericardium: visceral and parietal are separated by the pericardial cavity, which contains 20 to 60 mL of the plasma ultrafiltrate. The pericardium acts as mechanical protection for the heart and big vessels, and a lubrication to reduce friction between the heart and the surrounding structures.
What are the 3 layers of pericardium?
It can be divided into three layers, the fibrous pericardium, the parietal pericardium, and the visceral pericardium.
What organs are found in the abdominal cavity?
The abdomen contains many vital organs: the stomach, the small intestine (jejunum and ileum), the large intestine (colon), the liver, the spleen, the gallbladder, the pancreas, the uterus, the fallopian tubes, the ovaries, the kidneys, the ureters, the bladder, and many blood vessels (arteries and veins).
Which organ is located inside the pleural cavity?
The pleural cavity surrounds the lungs in the thoracic cavity. There are two pleural cavities, one for each lung on the right and left sides of the mediastinum. Each pleural cavity and it’s enclosed lung are lined by a serous membrane called pleura.
What are 5 organs found in the thoracic cavity?
Thoracic cavity: The chest; contains the trachea, bronchi, lungs, esophagus, heart and great blood vessels, thymus gland, lymph nodes, and nerve,.
What body cavity is the liver in?
Anatomy of the liver The liver is located in the upper right-hand portion of the abdominal cavity, beneath the diaphragm, and on top of the stomach, right kidney, and intestines.
How many organs are in the thoracic cavity?
It contains the lungs, the middle and lower airways—the tracheobronchial tree—the heart, the vessels transporting blood between the heart and the lungs, the great arteries bringing blood from the heart out into general circulation, and the major veins into which the blood is collected for transport back to the heart.
Is the pericardial cavity retroperitoneal?
retroperitoneal: Located outside of the peritoneum. serous membrane: A thin membrane that secretes serum that lines an internal body cavity, such as the peritoneum, the pericardium, and the pleura. intraperitoneal: Within the cavity of the peritoneum.
What connects pericardial and peritoneal cavities?
Thus, the embryonic coelom features an anterior-ventral pericardial compartment, a caudal peritoneal compartment, and bilateral pleural compartments (channels) connecting the pericardial and peritoneal compartments. Mesoderm lining the coelom forms mesothelium.
What are the body cavity?
A body cavity is a fluid-filled space inside the body that holds and protects internal organs. Human body cavities are separated by membranes and other structures. The two largest human body cavities are the ventral cavity and the dorsal cavity. These two body cavities are subdivided into smaller body cavities.
Which organ is surrounded by the pericardium?
Your heart is surrounded by a double-layered membrane, called the pericardium or pericardial sac. This membrane keeps your heart in place in your chest cavity, restricts the expansion of your heart when your blood volume increases, and helps to protect your heart.
What is the most superficial component of the pericardial cavity?
The fibrous pericardium is the most superficial layer of the pericardium. It is made up of dense, and loose connective tissue which acts to protect the heart, anchoring it to the surrounding walls, and preventing it from overfilling with blood.
What is endocardium myocardium and pericardium?
The heart wall is comprised of three layers. The endocardium is the innermost layer, and the muscular middle layer is the myocardium. The epicardium is the outermost layer of the heart wall, and also the innermost layer of the protective pericardium that surround the heart.
