Anatomy of the Heart
How many chambers of the heart are there
4
How does blood enter the heart?
Superior and Inferior Vena Cava
When we take a blood pressure what are we measuring?
the pressure of blood circulating on the walls of the arteries
This refers to one complete heartbeat consisting of the systole and diastole of the atria and ventricles
cardiac cycle
The main purpose of pulmonary circulation is to
return oxygenated blood to the heart from the lungs
What chambers of the heart are considered the receiving chambers
Atria-Atrium
Which part of the cardiac conduction system stimulates the left and right ventricles to contract simultaneously?
Purkinje Fibers
What instrument is used to measure blood pressure?
Sphygmomanometer
What is Pulmonary Circulation
transports deoxygenated blood from the body tissues to the lungs where gas exchange occurs
True or False Veins always carry deoxygenated blood
False
aortic semilunar valve
Which vessels bring oxygenated blood back to the heart?
Pulmonary Veins
What is a cerebrovascular accident (CVA)?
stroke
What is Systemic Circulation
transport oxygenated blood from the lungs to body tissues
Which layer of the heart contains muscle cells?
Myocardium
What is located between the right atrium and right ventricle
tricuspid valve
Name the flow of Oxygenated Blood
Pulmonary Veins, Left Atrium. Bicuspid Valve, Left Ventricle, Aortic Semilunar Valve, Aorta, Body
What is another name for a heart attack?
Myocardial Infarction
What happens during atrial systole
blood exits the atria
A pulse can only be detected in which type of blood vessel?
Artery
Which chamber of the heart has the thickest myocardium?
Left ventricle
Name the flow of Deoxygenated Blood
Superior/Inferior Vena Cava, Right Atrium, Tricuspid Valve, Right Ventricle, Pulmonary Semilunar Valve, Pulmonary Trunk, Pulmonary Artery, Lungs
What is the abnormal dilation of an artery or vein
Aneurysm
What is known as being the primary pacemaker of the heart?
SA Node
These are small vessels which carry blood from the arterioles to the venules
capillaries
