Answer 1

$\huge\sf\red{\underline{\underline{Ur \:Answer:-}}}$

• Heartbeat is defined as the pulse of your heart, or a single short moment, or something that acts as a unifying force.
• A heartbeat is a two-part pumping action that takes about a second. As blood collects in the upper chambers (the right and left atria)
• The heart's natural pacemaker (the SA node) sends out an electrical signal that causes the atria to contract.
• When your heart pulses and pumps blood throughout your body, this is an example of a heartbeat.
