In mammals and birds there's no sinus venosus instead they have the?
Mammals and birds do not have a sinus venosus but rather a sinoatrial node. The sinoatrial node is a remnant of the sinus venosus and performs the function of a pacemaker for the heart.thank god for this site :)
What is the most important structure of the human heart?
It is supposed to be the sinus node and the conducting tissue. It includes the AV node and bundle of HIS. The sinus node generate the impulse in the heart for contraction. The AV node and bundle of HIS transmits the impulse to the ventricles.
What node is located in the inferior portion of the interatrail septum?
the AV node.
What is a group of cells located in the right atrium that send out signals that you make the heart muscle contract or beat?
The sinoatrial node, or SA node. This group of cells initiate the electrical impulse through the heart in a normal heart rhythm, also called a normal sinus rhythm. Impulses can begin in other areas of the heart, but this typically causes an irregular heart beat.
Is sensitive tissue in the right atrium wall that begins the heartbeat called atrioventricular node?
The sino-atrial node (SA node) and, specifically the tissue of Bachmann's Bundle located within the SA node.

What controls the firing of the sinus node to trigger the start of the cardiac cycle?
Sinus node
What is the internal pacemaker of the heart called?
SA node (Sinus Node)
Which heart structure does the pacemaker substitute?
The SA Node.
What is natures pacemaker?
sinus node
What is a sinus rhythm?
When the heart is functioning properly the sinus node controls the firing of action potential that contract the heart. When the sinus node dominates the heart will contract in a synchronized and effective rhythm This is called sinus rhythm.
What is the internal pacemaker of the human heart called?
SA node (Sinus Node)
What is the most important structure of the human heart?

What is sinus arrest?
When the Sino-atrial node fails momentarily to initiate an impulse, sinus arrest occurs. When the sino-atrial node fails momentarily to initiate an impulse, sinus arrest occurs.
What is sinus braydicardia?
Sinus bradycardia is basically a decreased heart rate. It originates from the sinus node and will be under 60 beats per minute.
Where in the heart is the heart beat controlled?
Simple answer is sinus node
What is the main pace maker of the heart?
The primary pacemaker of a normal healthy heart is the sinus node (or SA node). It is located in the right atria of the heart.
