What is the Heart?
The heart is a vital organ of the human body. It is located in the left hand-side of your chest. But how does the heart work? Here’s how:
Function of the Heart:
– To pump blood through the body
– To provide oxygen rich blood required to live.
The heart is made up of four different blood-filled areas or chambers. There are two chambers on each side of the heart. Think of it as a double-storey building with two apartments each on the bottom floor and two directly on top.
The chambers on the top are the left and right atrium. The ones at the bottom are the left and right ventricle. The chambers of the heart together make it work as a double pump.
Oxygen rich blood flows from the lungs to the left atrium. It is then pumped out to the rest of your body from the left ventricle.
Meanwhile, the de-oxygenated blood enters the heart through the right atrium. It then flows into the right ventricle and gets pumped to the lungs, where it gets oxygenated again. All this happens in a single heartbeat and your heart does this all day and all night for your entire life.
A normal heart beats at 72 beats per minute, and will beat approximately 2.5 billion times during an average lifespan of 66 years.
