Cardiac Cycle for Dummies

Hey there! So, the term "cardiac cycle" refers to the series of events that happen in your heart as it beats. Let's break it down so it's easier to understand.

First, when your heart beats, it goes through a sequence of actions that allow it to pump blood around your body. This sequence is what we call the "cardiac cycle." It's kind of like a dance routine your heart does every time it beats.

During the cardiac cycle, your heart goes through two main phases: the diastole and the systole. In the diastole phase, the heart relaxes and fills up with blood. It's like a balloon slowly getting inflated with air. Then, in the systole phase, the heart contracts and pumps the blood out to the rest of your body. It's like the balloon squeezing out the air.

So, to sum it up, the cardiac cycle is the process your heart goes through every time it beats, involving two main phases: filling up with blood and then pumping it out. It's like a well-choreographed dance that keeps your body running smoothly. And that's the basic idea of what the cardiac cycle means. Remember, your heart is the star of the show, and the cardiac cycle is its routine! Hope that makes sense!
