|
|
|
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
|
Bruit
|
|
|
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?
|

|
|
|
Bundle of fibers that encircl and are embedded in the myocardium and its function
