What else can I help you with?
When the ventricular walls contract the what?
The bicuspid valve opens and the tricuspid valve closes.
What causes the atrio ventricular valves to close?
The rise in pressure inside the ventricles, when the walls of the ventricles contract.
Which wave is larger the one for atrial contraction or the one for ventricular contraction?
The wave for ventricular contraction is larger than the wave for atrial contraction. This is because the ventricles have thicker muscle walls and contract more forcefully in order to pump blood out to the body.
What is the most frequent initial rhythm witnessed in sudden cardiac arrest?
The most common abnormal heart rhythm preceding cardiac arrest is ventricular fibrillation. In this dysrhythmia, the ventricular walls contract randomly and rapidly, and do not effectively pump blood.
What are the walls that separates the chambers of the heart?
inter ventricular septum
In what organ system is the purkinje fibers?
Inner ventricular walls of the heart, beneath the endocardium.
When holding a heart how do you orient the right from left side?
by noticing the thickness of the ventricular walls
In blood pressure readingsystolic pressure is most closely associated with the?
Ventricular contraction. When ventricular pressure exceeds arterial pressure, the ventricles contract and eject blood into the aorta.
What part of the conduction system of the heart wraps around in the outer walls of the ventricular?
purkinje fibers
How many seconds does the Ventricular systole last?
The ventricular systole lasts for about 0.3 seconds, during which time the ventricles of the heart contract to push blood out into the arteries.
The greatest force of the blood against the walls of the arteries during ventricular contraction is called?
That is the Systolic Pressure.
Cerebrospinal fluid is formed from these blood vessels and glial cells that line the ventricular walls?
choroid plexus
