Cards

Term
behind the sternum
Definition
What is the heart located?
Term
Apex, 5th intercostal space
Definition
What is the PMI and where do you find it.
Term
Atrioventricular Septum
Definition
What separates the left and right side of the heart?
Term
Superior Vena Cava-> R Atria-> Tricuspid Valve-> R Ventricle-> Pulmonary Valve-> Pulmonary Artery-> lungs-> Pulmonary Veins-> L Atria-> Mitral Valve-> L Ventricle-> aortic valce-> aorta
Definition
How does the blood flow through the heart?
Term
Mitral
Tricuspid
Definition
What are called the atrioventricular valves (AV Valves)
Term
Aortic
Pulmonic
Definition
What are called the semilunar valves?
Term
found in the Epicardium
Definition
Where are the coronary arteries found?
Term
carry oxygenated blood to the tissues
Definition
Arteries do what in the body?
Term
carry unoxygenated blood to heart
Definition
Veins do what in the body?
Term
SA node is located at the top of the R Atria. Starts the conduction system
Definition
SA node is located where in the heart, and what does it do?
Term
AV node is located at the bottom of the R Atria.
Definition
Where is the AV node located?
Term
Bundle of His is located in the atrioventricular septum.
Definition
Where is the Bundle of His located?
Term
It makes the heart contract.
Definition
What does the Purkinjie fibers do?
Term
SA Node-> AV Node-> Bundle of His-> Purkinje Fibers
Definition
What order does the conduction system go?
Term
Pt will most likely need a pacemaker.
Definition
What happens if the SA and AV nodes stop working?
Term
60-100 bpm
Definition
What is a normal heart heart if the SA node is working?
Term
40-60 bpm
Definition
What is the expected heart rate if the SA node stops working but the AV node is?
Term
SV node will decrease
Definition
If contractility of the heart is decreased what often happens?
Term
afterload is increase = decreased SV
Definition
If vessels are constricted, what happens do the afterload?
Term
heart rate increases
blood vessels constrict
BP increases
the heart has a more forceful contraction
Definition
What happens to the body during a sympathetic response?
Term
heart rate decreases
dilated blood vessels
BP decreases
the heart has a decrease strength with contraction
Definition
What happens to the body during a parasympathetic response?
Term
Contraction and relaxation of our heart, each heart beat is one cardiac cycle?
Definition
What is the cardiac cycle?
Term
The amount of blood ejected by the heart every minute.
Definition
What is cardiac output?
Term
The amount of blood ejected with each ventricular contraction
Definition
What is stroke volume?
Term
preload
contractility
afterload
Definition
What factors influence stroke volume?
Term
dilation
Definition
Afterload is decreased by what?
Term
SV will be decreased
Definition
If out preload is high or SV will be?
Term
Cardiac output will be increased
Definition
If our SV is increased are CO will be?
Term
heart rate x stroke volume = CO
Definition
How do you calculate CO?
Term
4-8L/min
Definition
What is a normal CO?
Term
Small vessels that branch off arteries and send blood to capillaries.
Definition
What are arterioles?
Term
They distribute oxygenated blood from arteries to tissues of the body. Also, feeds deoxygenated blood into our veins.
Definition
What do capillaries do?
Term
Small vessels that branch off veins and send deoxygenated blood to our veins from our capillaries.
Definition
What do venules do?
Term
Takes deoygenated blood to the heart.
Definition
What do veins do?
Term
The whole body except the heart and lungs.
Definition
What is systemic circulation?
Term
Circulation of blood between heart and lungs, and back.
Definition
What is pulmonary circulation?
Term
Aorta-> Arteries-> Arterioles-> Capillaries-> Venules-> Veins -> HEART
Definition
What is the circulation of blood?
Term
count apical and radial pulse, and compare
Definition
What is a pulse deficit?
