MY HEART By Jennifer Wendt

《我的心》詹妮弗·温特著

THE INSIDE SCOOP Your body is a super machine that keeps you moving, learning, and having fun. But how does it work? The secret is inside! Show me some love by learning all about me!

你的身体是一台超级机器，它让你不停地运动、学习和享受乐趣。 但它是如何工作的呢？秘密就在里面！了解我的一切，给我一些爱！

When you run fast, you might feel a pounding in your chest. That's your heart working hard to help you play. Let's take a closer look.

当你跑得快的时候，你可能会感到胸口砰砰作响。 那是你的心脏在努力帮助你玩耍。 让我们仔细看看。

PUMPING POWER Your heart is a muscle that pumps blood all over your body. It is pounding in the middle of your chest to keep you going. Your heart beats about 70 to 115 times every minute!

心脏是一种将血液输送到全身的肌肉。 它在你的胸部正中砰砰作响，让你继续前进。 你的心脏每分钟跳动70到115次！

With each heartbeat, your heart opens up and fills with blood. Then, your heart squeezes tight like a fist. It pushes blood to the rest of your body.

每一次心跳，你的心脏都会打开，充满血液。 然后，你的心脏像拳头一样紧紧地挤在一起。 它把血液输送到身体的其他部位。

HEART PARTS The heart is made up of four different parts, called chambers. They split the heart from side to side and top to bottom. An adult's heart is about the size of their fist.

心脏由四个不同的部分组成，称为腔室。 他们把心脏从一边切到另一边，从上到下。 成年人的心脏和他们的拳头差不多大。
