Frank–Starling law of the heart
Imagine that your heart is like a balloon. When you fill up the balloon with air, it stretches and gets bigger. The same thing happens with your heart. When your heart fills up with blood, it also stretches and gets bigger. This is called the Frank-Starling Law of the Heart.
The Frank-Starling Law of the Heart is important because it helps your heart to pump blood effectively. When your heart fills up with blood, it stretches the heart muscle fibers. This stretching signals the heart to contract more strongly, which helps to force the extra blood out of your heart and into the rest of your body. This is important because your body needs a steady supply of oxygen and nutrients that are carried in your blood.
So, just like when you blow up a balloon and it gets bigger, when your heart fills up with blood, it gets bigger and contracts more strongly. This helps your body get the oxygen and nutrients it needs to keep you healthy and strong.
