The division between right and left heart is called?
Atrium
What sends electric currents to the heart causing it to beat at a steady pace?
The "cardiac pacemaker," a group of cells in the sinoatrial node of the right atrium of the heart, which generate regular electrical impulses causing the heart to beat. The rate of contraction is regulated up or down by nerve fibers originating from elsewhere in the body.
What does the blood pass through to get to the right ventricle?
Blood passes through the right atrium to the right atrioventricular valve, or "AV valve" for short, into the right ventricle during pulmonary contraction.
What are the two heartbeat sounds?
The normal sinus rhythm sounds like a "lub-dub". The "lub" is the sound of the two atrioventricular valves (mitral for left atrium to left ventricle, tricuspid for right atrium to right ventricle) closing immediately after atrial contraction and then relaxation. The "dub" is the sound of the two sumilunar valves (aortic for left ventricle to aorta, pulmonary for right ventricle to pulmonary artery) closing immediately after ventricular contraction and then relaxation.
Is it possible for a microwave oven to affect cardiac pacemaker and if so how?
although many microwaves have warnings, they are baseless and there is no evidence of danger.
What in the right atrium is frequently called the pacemaker?
sinoatrial
What is a group of cells in the right atrium that regulates a heartbeat called?
pacemaker
The pacemaker of the heart is located where?
The anatomical pacemaker is located in the right atrium
Where is located the pacemaker?
The pacemaker is located on the outside of the right atrium.
Where is the Natural pacemaker?
The SA node, the natural pacemaker of the heart, is found in the right atrium of the heart.
Sensitive tissue in the right atrium that begins the heartbeat?
Pacemaker (sinoatrial node)
What kind of pacemaker has leads going to the right atrium and the left ventricle?
Dual.
The natural pace maker of the heart is called?
The natural pacemaker of the heart is called the sinus node. This is made up of a cluster of cells that are in the upper right part of the wall of the right atrium.
Describe the location and action of a pacemaker?
Pacemaker is located in the right atrium and generates electrical impulses to start a muscle contraction in the heart.
What is the modified cardiac muscle cells in right atrium producing regular electrical impulses called?
The sinoatrial node (also called the sinus node) is the impulse generating (pacemaker) tissue located in the right atrium of the heart, and thus the generator of sinus rhythm.
In which chamber of the heart would you find the pacemaker?
The ventricles has the strongest wall .
What Special tissue in right atrium that regulates heartbeat?
Sino-atrial node(SA node), it's also called natural Pacemaker.
