What does your heart do? Your heart is the center and key organ of the cardiovascular system, working along with your blood, veins, and arteries. Our body’s cardiovascular system serves to circulate blood throughout our body, delivering fresh oxygen to our cells! Blood also helps to remove unwanted waste, control your body temperature, and fight infection! Without blood, we couldn’t survive!
The heart controls the cardiovascular system by continuously pumping blood throughout the rest of the body. This hollow organ is a muscle, contracting and pushing the blood in your body a little further. The heart beats 60-100 times each minute, the rate of your heartbeat is called a pulse. The more you move, the more quickly your heart beats to supply your body with fresh blood. Your heart beats 100,000 times each day, 35 million times a year, and 2.5 billion times over your lifetime! The heart works very hard to keep you alive!
There are 4 chambers in the heart, two chambers receive blood from the body, while the other two release fresh blood into the body! Arteries and veins are like tiny straws spread throughout your body helping your heart carry blood. The arteries carry blood away from the heart, while veins bring blood back to the heart. Blood vessels work similarly to arties and veins but are much smaller and cover more ground. When you fall and get a bruise, you’re seeing broken blood vessels!
Your heart works very hard to keep you alive, so you should work hard to keep your heart healthy! Keep your heard healthy by eating lots of healthy food, exercising regularly, and keeping away from smoking!
