Your heart is like a mega pump because it is shaped like an upside-down pear and is one of the most important organs in your body. When a person rests, their heart rate slows, but when they exercise, their heart rate increases. For my hypothesis, I predicted that older people would have a lower resting heart rate than younger people. The heart is an interesting and important organ. It may seem strange, but the heart is not red. It's almost the color of a brick colonial house. Like all other pumps, your heart can also become clogged. The heart is actually a strong muscle in your body. Your heart pumps oxygen-rich blood to every organ in your body. Heart rate varies with age. A younger person's heart may beat faster than an older person's heart. Your heart may beat at different rates depending on what you are doing. The heart cannot rest until a person dies. A heart can become ill and damaged. Some heart diseases can cause sudden death because the disease is so strong that it breaks the heart. Sometimes, when a woman has a heart attack, she doesn't even know it. A bigger heart is not a better heart, because a bigger heart can cause more problems because it can attract more diseases. Emotions or stress can break your heart because stress can cause certain hormones that can paralyze part of your heart. A common cold can also damage the heart because blocked arteries and leaky heart valves can damage the heart. If your heart is stressed you cannot sleep well. There are some things that can help your heart be healthy. Some foods like oatmeal, salmon, avocado, olive oil, nuts, berries, legumes, s...... middle of the paper... important thing. As for my hypothesis, I was right because as you get older your heart rate changes. This means that as you get older, you still need to take care of your heart. I learned that the heart is the most important organ in the body, so that means as you get older, get your heart right. Work cited "How the heart works". Netdoctor. Np, nd Web.
