Two main pumping chambers of the heart
atria and ventricles
Another name for the atria
Receiving vs. Pumping chambers
atria is receiving
Ventricles pump
Heart muscle
the heart is enclosed in a sac known as
Lining inside the sac
The membrane that lines the atrium and ventricles and the illness if it becomes inflammed
carries blood away from the heart
carries blood to the heart
describe how the pericardium works
pericardial activity- piece of folded paper wrapped around- epicardium touches heart, lubrication between that and the pericardium
Separates heart chambers longitudinally
cardiac septum
portion of it that divides the atria
interatrial septum
divides the ventricles
interventricular septum
Vein that brings deoxygenated blood back to the heart from the upper half of the body
superior vena cava
Vein that brings deoxygenated blood back to the heart from the lower half of the body
inferior vena cava
where do the venae cavie deposit the deoxygenated blood?
Into the right atrium
Where and through what does the blood go after it enteres the atrium?
through the tricuspid valve into the right ventricle
Where the blood goes after the right ventricle
Pulmonary trunk-- (artery)
left/right pulmonary artery
Splits in two
What is the right side of the heart designed to do?
send blood to the lungs
tendons linking the papillary muscles to the tricuspid valve
heart strings or chordae tendineae
Muscles that tighten to close the tricuspid valve, eliminating backflow
papillary muscles
interrupts with the proper amount of blood getting to the lungs.
the flaps of the tricuspid valve will make a sound and a problem with the valves and a backflow of blood
where does blood to the right and left pulmonary arteries go?
right PA - right lung
left PA - left lung
where does oxygenated blood go to?
left atrium
takes the oxyginated blood from the lungs to the heart
Pulmonary veins- four of them
Where does the pulmonary circuit extend and what is it?
The direction or the circulation of the blood which goes to the lungs---extends from the heart, to the lungs, back to the heart.
Where does the systemic circuit extend to and what is it?
The blood going away from the heart with fresh blood to nourish the system
Extends from the heart to the body’s cells and back to the heart
another name for tricuspid
atriventricular valve
Another valve emerging from the right ventricle
pulmonary semilunar valve
Abnormal circulatory sound heard over a blood vessel usually due to some constriction
The blood, from the left atrium, is pushed into the left ventricle through a valve called the
mitral or bicuspid valve- two flaps
constriction or narrowing of the mitral valve
Mitral stenosis
when the little flaps fly up into the atrium, causing backflow of the blood.
Mitral valve prolapse
Which side of the heart muscle is thicker and why?
left- needs to have enough force to pump blood throughout the body
Blood in the left ventricle leaves via what?
the aorta
heart muscle that contracts without motor nerves
aortic semilunar valve
bundle of specialized cardiac cells in the right atrium and its aka and how often it fires
sinoatrial node, aka pacemaker of the heart aka SA Node- fires 45 times a min
what's the significance of the pacemaker?
creates the heartbeat sound
a bundle of nerve cells specialized for electrical conduction that transmits the electrical impulses
Bundle of His
a “relay station” which then goes to the Bundle of His. In the right atrium
atrioventricular node- AV node.
where does the Bundle of His send impulses to?
the ventricles
Bundle of fibers that encircl and are embedded in the myocardium and its function
purkinje - conduct an electrical stimulus or impulse that enables the heart to contract
interruption of some kind in the transmission of the electrical impulses of the heart beat.
heart block
Disorganized heart beat - heart muscles not contracting in unison
How many degrees of heart block are there?
at the base of the aorta on each side and its function
coronary artery - Provide the heart muscle with its own supply of fresh blood.
System of veins that collect the used blood from the heart muscle and dump it into the right atrium
cardiac veins
all the veins in the heart muscle come together and form this
coronary sinus
physical blockage of a coronary artery and its medical term
heart attack, myocardial infarction
formation of a blood clot
coronary thrombosis
The hollow space of an organ or blood vessel
the area of necrotic tissue in the heart, which is a result of a heart attack.
Points on an electrocardiogram
Labeled as P, Q, R, S, T
What do the P and T mean?
P - atrium
T - ventricles
The name for the cords stuck on a patient’s body
Skipped or irregular heartbeat.
An abnormally fast heartbeat-- name and how fast is fast?
tachycardia - usually over 100 beats per min
Too slow of a heart beat
Bradycardia - under 100 beats per min
Moving blood clot
Hardening of the arteries themselves
chest pain
angina pectoris, or anginal (adj.)
another definition for angina
Also refers to a condition where a person has recurring spasming of the coronary arteries— symptoms similar to a heart attack, but it’s not.
A reduction in blood supply
ischemia, ischemic (adj.)
weird name for heart sounds
rub and a gallop
squeaky sound made by an inflammed pericardium
extra heartsound, extra beat
period of the heart’s contraction
systole, systolic (adj.)
period of the heart's relaxation
diastole, diastolic (adj.)
Example of blood pressure
120/80 = systole/diastole
opening in fetal heart - explain and name
between r/l atrium - called foraman ovale
after the openign in the fetal heart closes, it is called:
fossa ovalis
Little bit of material of the right atrium of the fetal heart which helps push the blood from the right atrium to the left atrium
eustachian valve
Intercommunication of blood vessels
anastomosis, anastomotic
region/area on your chest above your heart
precordium, precordial (adj.)
