Heart: More Than a Pump

The human heart beats around 100,000 times daily, circulating blood through 60,000 miles of blood vessels. That's enough to encircle the Earth more than twice!

Your heart has its own electrical system, governing beats with a natural pacemaker called the sinoatrial node, located in the right atrium.

The size of your heart is approximately that of your clenched fist. Contrary to popular belief, it sits at the center of the chest, tilted slightly left.

The heart has a limited capacity to regenerate itself. Unlike skin or liver, heart cells renew at a far slower rate, about 1% annually.

Every person's heartbeat has a unique signature. It's so distinct that it can be used as a biometric identifier, similar to fingerprints.

Cardiac asthma isn't a form of asthma; it's a type of coughing or wheezing that occurs with left heart failure.

An athlete's heart can be up to 50% larger than non-athletes'. This is due to the heart's adaptation to sustained high-intensity training regimes.

The heart contains about 40,000 neurons, forming a 'heart brain' that can sense, feel, and remember independently of the brain.
