Cardiovascular Anatomy
This part of the heart points toward the left hip. The bottom of the heart
What is an Apex?
This is another name for the mitral valve
What is Bicuspid valve?
The first sound of the heart (the lub) is associated with
What is the closing of the tricuspid and bicuspid valves?
heart rate less than 60bpm
What is bradycardia?
thin outer layer of the heart (also called the visceral layer of the serous pericardium)
What is Epicardium ?
The thick middle, muscle layer of the heart
What is Myocardium?
Main function/purpose of the atrioventricular (AV) and semilunar valves (hint:regarding atria and ventricles)
What is prevent blackflow?
prevent black flow into the atria when ventricles contract
When taking the blood pressure, this part of the blood pressure is the measure of the pressure in the arteries during ventricular contraction
What is Systolic Pressure?
A rapid heart rate over 100 PBM
What is tachycardia?
Percentage of blood that is ejected from the heart during systole. Normal is 50% to 70%. Value decreases with heart failure.
What is ejection fraction?
Separates the heart into right and left halves of the heart.
What is the septum?
This semilunar valve of the heart is between the right ventricle and the pulmonary artery and has three cusps.
What is pulmonary valve?
heard when blood volume is increased in the heart, or the blood is impeded or altered from normal; blowing or swishing sound
What is murmur?
When taking blood pressure, this part of the blood pressure refers to the blood pressure in the arteries during ventricular relaxation
What is diastolic pressure?
medical name for a heart attack
What is myocardial infarction?
Path of blood flow of deoxygenated blood to oxygenated blood (describe from right atrium to lungs, include the valves)
right atrium, tricuspid valve, right ventricle, pulmonary semilunar valve, pulmonary artery and then lungs to become oxygenated
This heart valve separates the left atrium from the left ventricle. Opens to allow blood to be pumped from the lungs to the left atrium. Prevents the back flow of blood from the left ventricle to the left atrium.
bicuspid/mitral valve
Oxygenated blood returns form the lungs to the heart via these vessels
What is Pulmonary Veins?
Represents the QRS complex on an EKG
what is the depolarization of the ventricles
Within the conduction pathway, this part of conduction is considered the pacemaker of the heart
What is SA node?
Path of oxygenated blood from the lungs
Lungs via the pulmonary veins, left atrium, mitral (bicuspid) valve, left ventricle, aortic semilunar valve aorta, and out to the body
Which valve is passed through first in the pathway of blood through the heart? (hint: the phrase used with shopping or buying)
Tricuspid valve
The path an impulse takes in the conduction system of the heart.
SA node, AV node, AV bundle (bundle of HIS), right and left bundle branches, Purkinje Fibers
The EKG wave that represents depolarization of the atria
What is P wave?
also called hypertension; risk factors include smoking obesity, and lack of exercise
high blood pressure
