This Valentine's Day, millions of people will exchange heart-shaped gifts of all kinds, from candy to cards. But did you know that the human heart does not actually look like the typical valentine shape?

今年的情人节,无数人会交换各式各样的心形礼物,从糖果到卡片不一而足。但你知道人类的心脏其实与典型的情人节心形不尽相同吗?

We spoke with heart specialist[专家] Robert DiBianco to learn more about this important organ.

我们与心脏科专家罗伯特·迪比安科聊了一会儿,以便更清楚地了解这个重要的器官。

According to Dr. DiBianco, the human heart is about the size of a fist.

据迪比安科医生说,人的心脏与其拳头的大小相仿。

“Because the heart is a muscle with lots of blood supplied to it, it looks red like meat,” he explained. “In people who are overweight…the heart looks yellow because it is covered with yellow fat.”

“因为心脏是一块有许多血液供应于其间的肌肉组织,所以它看起来就像肉一样鲜红,”他解释道。“而对于那些体重过重的人……他们的心脏看起来是黄色的,因为它被黄色的脂肪包裹着。”

In the United States, children are taught to place their hands over their hearts when pledging allegiance to the flag. Most people have heard that the heart is on the left side of the chest. In reality, the heart is in the middle of the chest, tucked snugly  between the two lungs. It's tipped slightly so that a part of it sticks out and taps  against the left side of the chest, which is what makes it seem as though it's located there.

在美国,人们教小孩子在对旗帜宣誓效忠时,要将手按在心口上。大多数人都听说过心脏位于胸腔的左边。但事实上,心脏位于胸腔的中间,紧紧地包裹在两片肺叶之间。它略微倾斜,一部分突出在外并与左胸腔相连,这就是为什么它看起来好像位于左侧。
