   The heart sits within a fluid-filled cavity called the pericardial cavity. The walls and lining of the pericardial cavity are a special membrane known as the pericardium. Pericardium is a type of serous membrane that produces serous fluid to lubricate the heart and prevent friction between the ever beating heart and its surrounding organs. Besides ...

   The heart wall is made of 3 layers: epicardium, myocardium and endocardium. 1. Epicardium. The epicardium is the outermost layer of the heart wall and is just another name for the visceral layer of the pericardium. Thus, the epicardium is a thin layer of serous membrane that helps to lubricate and protect the outside of the heart. Below the epicard...

   The heart contains 4 chambers: the right atrium, left atrium, right ventricle, and left ventricle. The atria are smaller than the ventricles and have thinner, less muscular walls than the ventricles. The atria act as receiving chambers for blood, so they are connected to the veins that carry blood to the heart. The ventricles are the larger, strong...

   The heart functions by pumping blood both to the lungs and to the systems of the body. To prevent blood from flowing backwards or "regurgitating" back into the heart, a system of one-way valves are present in the heart. The heart valves can be broken down into two types: atrioventricular and semilunar valves. 1. Atrioventricular valves. The atriove...

   The heart is able to both set its own rhythm and to conduct the signals necessary to maintain and coordinate this rhythm throughout its structures. About 1% of the cardiac muscle cells in the heart are responsible for forming the conduction system that sets the pace for the rest of the cardiac muscle cells. The conduction system starts with the pac...

   Where is the heart located?

   • The heart is located within the ventral body cavity. Recall that the ventral body cavity is further subdivided into the thoracic cavity and the abdominopelvic cavity, separated by the diaphragm. The heart is located within the thoracic cavity. Between the two lungs and their cavities (pleural cavities) is a central cavity called the mediastinum.

   Where is the heart located inside the mediastinum?

   • The heart is located inside of the mediastinum in an inner cavity called the pericardial cavity. Serous membranes form the pericardial cavity with the outer layer being the parietal pericardium and the inner layer being the visceral pericardium (also known as the epicardium ).

   How does blood flow through the thorax?

   • As the muscles surrounding the veins contract and relax, the blood is squeezed, or “milked,” through the veins toward the heart (Figure 11.11). Finally, the drop in pressure that occurs in the thorax just before we inhale causes the large veins near the heart to fill.
