It causes the cells of the heart muscle to contract in the correct sequence, and ensures regular, efficient, and coordinated heartbeats. For this reason, the sinus node is often referred to as the heart's "natural pacemaker."

The embryonic heart forms from multipotent cardiovascular progenitor cells that migrate to anterior lateral splanchnic mesoderm. The cardiac transcriptional program is activated by the combinatorial activities of multiple intercellular signaling pathways and transcription factors. WebEach day, your heart beats around 100,000 times. This continuously pumps about five litres (eight pints) of blood around your body through a network of blood vessels called your circulatory system. This blood delivers oxygen and nutrients to all parts of your body to help your organs and muscles work properly.
