A
This structure is known as the pacemaker of the heart
SA node
This valve separates the left atrium and left ventricle
Mitral (bicuspid) valve
A heart rate less than 60
Bradycardia
This valve separates the right atrium and the right ventricle
tricuspid
A traveling blood clot is known as this
embolus
This chamber of the heart pumps blood to the lungs
Right ventricle
Blood from the lungs enters this chamber
Left atrium
Myocardium, thick muscle layer
The main artery that carries blood away form the heart to the rest of the body
Aorta
What type of blood does the pulmonary artery carry?
deoxygenated
What is the order of the valves in the heart?
Tricuspid, Pulmonic, Mitral, Aortic
The contraction and active phase of the heart
systole
area of weakness and dilation in the wall of an artery
aneurysm
abnormal heart sound due to faulty actions of the heart valves
murmur
smallest branch of an artery
arterioles
when administering an anti-arrhythmic, which vital sign do you need to check and how?
Heart rate--apical pulse
*Hold if HR less than 60
The inner most layer of the wall of the artery
Tunica intima
Name 2 causes of a heart murmur
Increased blood flow, increased blood volume, increased heart rate, decreased viscosity, valve damage
This part of the heart is located at the bottom, left, 5th intercoastal space
vibration of a wave of blood against the wall of an artery
pulse
Name 3 functions of the CV system
transports nutrients and waste products, carries oxygen and co2, aids in regulation of temperature, assist with acid/base fluid balance, transports hormones, aids in body's defenses
These antihypertensive medications end in the suffix
(-pril)
ACE inhibitors
These medications cause vasodilation and decreases nrve conduction through the heart in a patient with hypertension, angina, and arrhythmias
Calcium Channel blocker
What is the electrical conduction sequence through the heart?
SA node, AV node, Bundle of His, Purkinje fibers
decreased cardiac muscle strength, heart valves become thick and more rigid, SA nod less efficient, impulses are slowed, decreased stroke volume and cardiac output
