How can you tell when Valentine’s Day(情人节) is coming? All those heart-shaped chocolate boxes in the store are a good clue(线索). So are those boxes actually shaped like the heart inside your body?

In fact, your heart is not shaped like a heart. It looks more like a peach. It is about the size of your fist(拳头). In most cases, it is in the left of your chest(胸口). The human heart weighs about 250 grams. When a man is in a quiet state, his heart beats about 70 times a minute. When a person does very hard exercise, his heart beats can reach 150 to 180 times each minute.

The heart is one of the most important organs(器官) in the human body. It is made up of four “rooms”. When your heart contracts, the “rooms” get smaller. The main function (功能)of the heart is to provide pressure for blood flow and run blood to all parts of the body. When your heart relaxes, blood will come back into your heart and “rooms” get bigger.

Your heart keeps pumping blood throughout your body. It transports important nutrients to all the areas of your body. The health of the heart is very important to us. Please take care of your heart. Do you agree with my opinion?
