Cardiovascular System
Trachycardia
100 and up heart rate
Bradycardia
60 and below heart rate
Normal Heart Rate
60-100 beats per minute
This receives the impulse from the SA node.
AV node
Blood enters the (blank) from the left ventricle to be distributed throughout the body.
Aorta
The (blank) valve prevents blood from flowing back into the left ventricle
Aortic
Which of the following valves prevents blood from flowing back into the left ventricle
Aortic
The (blank) has three cusps, is situated between the right atrium and the right ventricle and prevents blood from flowing back into the left ventricle
Aortic valve
The (blank) valve is also known as the mitral valve
Bicuspid
Which valve is between the left atrium and left ventricle?
Bicuspid
The (blank) has two cusps and is located between the left atrium and the left ventricle.
Bicuspid Valve
Which component of the conduction system is located between the ventricles?
Bundle of His
Inflammation of the heart is called
Carditis
The (blank) is thin and smooth and is the innermost layer of the heart
Endocardium
The function of the four valves of the heart includes
Ensuring one way blood flow
This layer of the heart is the outermost layer and contains fat to cushion the heart.
Epicardium
Blood returns to the heart from the king by the way of the pulmonary arteries
False
Pulmonary arteries carry oxygenated blood.
False
The aorta carries blood to the lungs
False
Veins carry blood away from the heart
False
Veins carry oxygen rich blood
False
When in the lungs, the blood absorbs both oxygen and carbon dioxide
False
The pulmonary veins empty the oxygenated blood into the (blank)
Left Atrium
When the (blank) contracts, blood is pushed through the aortic semilunar valve into the aorta.
Left ventricle
Which of these covers the thickest layer of the heart, which is made up of muscle?
Myocardium
Sac of the heart is (blank)
Pericardium
Which of these covers the heart and the large blood vessels attached to it?
Pericardium
Which of the following valves prevents blood from flowing back into the right ventricle
Pulmonary
When the right ventricle contracts deoxygenated blood is pushed through the pulmonary semilunar valve into a larger artery called the (blank)
Pulmonary Artery
When the right ventricle contracts, deoxygenated blood is pushed through the pulmonary semilunar valve into a larger artery called the (blank)
Pulmonary Trunk
The (blank) empty oxygenated blood into the left atrium.
Pulmonary Valve
The (blank) prevents blood from flowing back into the right ventricle. It is called a senilunar valve because its cusps are shaped like a half moon.
Pulmonary Valve
After the impulse flows through the flow through the (blank), the ventricles contract and the SA node starts the flow of a new impulse.
Purkinje Fibers
The (blank) is/are location in the lateral walls of the ventricles.
Purkinje Fibers
Blood that is low in oxygen and rich in carbon dioxide enters the (blank) of the heart
Right atrium
When the (blank) contracts, blood is pushed through the pulmonary semilunar valve into a larger artery called the pulmonary artery trunk
Right ventricle
The (blank) is/are located in the wall of the right atrium
SA node
The is known as the pacemaker of the heart
SA node
The (blank) separates the ventricles
Septum
The atria are separated from each other by a walled membrane known as the (blank)
Septum
The walled membrane so wearing the ventricle is the (blank)
Septum
Cardiac Electrolytes
Sodium Potassium Chloride Calcium
Damaged heart valves often allow blood to flow backwards.
True
In the body, blood brings oxygen to the cells and carries carbon dioxide away.
True
Pulmonary veins carry oxygenated blood
True
Veins of the body pick up the oxygen poor blood and empty it into the superior and inferior (blank)
Vena cava
Arteries carry blood away from the heart
true
