5. Functions of the Heart
• Center of the cardiovascular system,
the heart = pump
• Connects to blood vessels that transport blood
between the heart and other body tissues.
• Arteries and veins entering and leaving the heart
are called the great vessels.

6. Functions of the Heart
• Ensures the unidirectional flow of blood
through both the heart and the blood vessels.
• Acts like two independent, side-by-side pumps
that work independently but at the same rate.
• Develops blood pressure through alternate
cycles of heart wall contraction and relaxation.

thoracic cavity - The closed, partially membrane-lined sterile anatomical space, a subdivision of the ventral body cavity, which houses the lungs, heart, and the organs of the mediastinum; its linings are the three serous membranes known as the pleural membranes and the pericardial membrane; it is located medially on the anterior of the trunk and housed within the confines of the rib cage; it provides a protected space for those organs.pleural cavity - The two closed, membrane-lined sterile anatomical spaces, subdivisions of the ventral body cavity and of the thoracic cavity, which houses the right and left lungs respectively; its lining is the serous membrane known as the pleural membrane; it is located lateral to the mediastinum and pericardial sac on the anterior of the trunk and housed within the confines of the rib cage; it provides a protected space for the lungs.pericardial cavity - The closed, membrane-lined sterile anatomical space, a subdivision of the ventral body cavity and of the thoracic cavity, which houses the heart; its lining is the serous membrane known as the pericardial membrane; it is located within the inferior portion of the mediastinum on the anterior of the trunk and beneath the sternum within the confines of the rib cage; it provides a protected, lubricated space for the heart to contract.mediastinum - The closed sterile anatomical space, not lined by a serous membrane, a subdivision of the ventral body cavity and of the thoracic cavity, which houses the heart in its pericardial sac, the great vessels, the trachea, the esophagus, and the thymus; it is located medially between the two pleural cavities to the right and left and between the thoracic vertebral column and the sternum.
