We have been learning all about the heart in fourth class. Here are some interesting facts about the heart.
Did you know?
- The heart pumps blood to all parts of the body.
- The blood brings oxygen to the muscles.
- Heart rate increases with exercise so that more of the oxygen carried in the blood can reach the muscles.
- The fitter you are, the quicker your heart rate returns to normal.
- An adult’s heart rate is around 70 beats per minute, and a child’s is a bit higher.
- A mouse’s is about 500 beats per minute, and an elephant’s is about 25 beats per minute!
- Our hearts are pumping at a regular rate. This pumping can be felt by placing fingers across the pulse point at the wrist or the neck, and the rate can be counted.
- Your heart is about the same size as your fist, and weighs about the same amount as a lemon.
- Your heart is located in your chest, near your lungs, and to the left of the hard bone in the middle of your chest (the breastbone).
- Your heart is an organ made of muscle.
- The heart is an important organ in the body. It helps deliver oxygen and nutrients that are in the blood to all the other organs in the body.
