Question

what is sinoatrial node?​

Answer 1

Explanation:

Sinoatrial node: The heart's natural pacemaker, one of the major elements in the cardiac conduction system, the system that controls the heart rate. ... The SA node consists of a cluster of cells that are situated in the upper part of the wall of the heart's right atrium, where the electrical impulses are generated.

Answer 2

• The heart's natural pacemaker, the Sinoatrial Node, is one of the key components of the cardiac conduction system, which regulates heart rate.
• The SA node is a cluster of cells located in the upper portion of the right atrium's wall, where an electrical signal created by the SA node travels down the heart from cell to cell until it reaches the atrioventricular (AV) node, a cluster of cells located between the atria and ventricles.
• Before the signal can flow down to the ventricles, the AV node acts as a gate, reducing the electrical current.
• There are electrical impulses produced.
