Chapter 22 The Heart Flashcards
vessels that take blood away from the heart
ARTERIES
vessels that bring blood back to the heart
VEINS
arteries and veins that enter and leave the heart
GREAT VESSELS
Blood flow through the heart is
unidirectional
The right side pumping blood to the lungs is called
PULMONARY Circulation
The left side pumps blood to the tissues of the body and is called
SYSTEMIC Circulation
the pressure of the blood pushing against the walls of the vessels
Blood Pressure
pressure of the pulmonary circulation is Low in relation to
pressure of the systemic circulation
Pulmonary Circulation carries blood from
the right side of the heart to the lungs then to the left side of the heart
Systemic Circulation carries blood from
the left side of the heart to the tissues of the body then to the right side of the heart
The heart is enclosed in a tough sac called
Pericardium
The Heart is located within the pseudo-cavity of
The Mediastinum
The outer layer of the Mediastinum
Fibrous Pericardium
The inner layer of the Mediastinum
Serous Pericardium
The Serous Pericardium and has two layers
Parietal Layer
Visceral Layer
Between the Parietal Layer and the Visceral layer is
Pericardial Cavity
The serous layer is so tightly associated with the surface of the heart that it becomes
Epicardium
-the outer layer, formed from the visceral layer of the pericardium
Epicardium
the middle layer of the heart wall, made up entirely of Cardiac Muscle Tissue
Myocardium
the inner layer of the hear wall, composed of Areolar Connective Tissue
Endocardium
receives blood from the body
Right Atrium
receives blood from the lungs
Left Atrium
pumps blood to the lungs
Right Ventricle
pumps blood to the body
Left Ventricle
What groove on the surface of the heart separates the atria from ventricles
Coronary Sulcus
The two ventricles are separated from each other anteriorly by
the Anterior Interventricular Sulcus
