Have you ever checked your pulse before? You can check your pulse on you wrist or on your neck. 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, the heart rate slows down, but when they are exercising the heart rate increases. For my hypothesis, I predicted that aged people would have a lower resting heart rate than the youthful people would.
The heart is an interesting and important organ. It may seem weird, but the heart is not red. It is almost the color of a colonial brick house. Like all other pumps, your heart can become clogged too. The heart is actually a strong muscle in your body. Your heart pumps oxygen-rich blood to every organ in your body. Your heart rate differs by age. A younger person’s heart can beat faster than an older person’s heart. Your heart can beat at different rates depending on what you are doing. The heart cannot rest until a person dies.
A heart can become diseased and damaged. Some heart diseases can cause sudden death because the disease is so strong, it breaks the heart down. Sometimes when a woman has a heart attack, she does not even know it. A bigger heart is not a better heart, because a bigger heart can cause more problem because more diseases can attract to it. Emotions or stress can break your heart because stress can cause certain hormones that can paralyze some of your heart. A common cold can also damage your heart because blocked arteries and leaky heart valves can damage your heart. If your heart is stressed out you cannot sleep as well.
There are some things that can help your heart to be healthy. Some foods like oatmeal, salmon, avocado, olive oil, nuts, berries, legumes, s...

...important thing. For my hypothesis, I was right because as you get older, your heart rate changes. That means that as you get older, you still have to take care of your heart. I have learned that the heart is the most important organ in your body, so that means as you get older, take of your heart correctly.

In the study it was hypothesized, that the pulse rate does not increase after a step test exercise. This hypothesis is not valid because the result of the step test proves otherwise. In the study, the individuals who participated in the step test took their pulse rates before and after the step test, looking at the overall results, figures and the averages of both tests, we can conclude that the step test exercise does affect the pulse rate of an individual.
The science and history of the heart can be traced back as far as the fourth century B.C. Greek philosopher, Aristotle, declared the heart to be the most vital organ in the body based on observations of chick embryos. In the second century A.D, similar ideas were later reestablished in a piece written by Galen called On the Usefulness of the Parts of the Body. Galen’s thesis was that the heart was the source of the body’s essential heat and most closely related to the soul. Galen made careful observations of the physical properties of the heart as well. He said “The heart is a hard flesh, not easily injured. In hardness, tension, in general strength, and resistance to injury, the fibers of the heart far surpasses all others, for no other instrument performs such continues, hard work as the heart”(Galen, Volume 1).
It’s the big day of the finals and you are experiencing some anxiety. You walk in the classroom and feel like your heart is going to jump out of your chest. This is a normal response to anxiety by the body known as sinus tachycardia. The heart is like a pump and needs to be taken care of for it to work properly. The heart has its own rhythm and on an electrocardiogram (EKG) should have a synchronous pattern called sinus. The normal sinus rhythm should be around 60-100 beats per minute (LeMone, Burke & Bauldoff, 2011). There are many factors that can change the rate and rhythm of the heart. When sleeping your heart rate tends to be slower and should be slower due to the decreased work load on the heart. Something as little as being excited or exercising can cause your heart rate to increase and due to signals to your heart telling it to beat faster to supply the body with more blood and oxygen. The heart can beat over 100 beats per minute at rest, even when supine so it is important to assess for symptoms of any complications (Olhansky & Sullivan, 2013). A normal rhythm, but faster than 100 beats per minute is called sinus tachycardia (LeMone et al., 2011).
· Eat moderate amounts of nuts that are rich in monounsaturated fat, like hazelnuts, almonds, pecans, cashews, walnuts and macadamia nuts. These nuts have been shown to improve cholesterol levels. Avoid eating nuts by the handful. Instead, garnish food with one tablespoon of chopped nuts per person.
Our heart is a muscle. Which means, our heart needs oxygen. A heart attack takes place when the blood flow that brings oxygen to the heart is stopped. This goes on because coronary arteries that helps supply
One of the leading causes of death in the United States is heart disease. “Approximately every 29 seconds one American will have a heart attack, and once a minute one American will die from a heart attack” (Ford-Martin and Odle, 915). According to the Gale Encyclopedia of Alternative Medicine men over the age of 45 and women over the age of 55 are considered at risk for heart disease. Heart disease is a major cause of death. It is beneficial to individuals who seek to prevent heart disease to recognize the risks leading to heart attacks as they are one of the primary indications of developing heart disease; especially those that fall into the at risk age groups. These risks consist of some that cannot be changed such as heredity risks, or those that can change such as smoking habits. It is very important to know these specific risks for prevention and to understand the symptoms of heart attacks, such as sweating or the feeling of weakness so if these or other symptoms occur people are aware. Finally heart disease treatment is of vital importance if you experience a heart attack so you can learn how to prevent another one from occurring.
Heart disease kills over 600,000 men and women in the United States every year. That translates to one out of every five deaths are caused by heart disease. Heart disease has several factors, but they all contribute to difficulty in blood flow from the heart. It is most often caused by an unhealthy lifestyle such as a poor diet, little exercise, being overweight and smoking. People die from heart disease several ways including heart attack or stroke.
Introduction: In year 10, biology, we have been studying the heart: the functions of the heart, the parts of the heart (ventricle, atrium) and heart problems. We have also been studying the heart rate of humans. We were asked to create an experiment to see what affects heart rate. We discovered that diet, stress, cholesterol levels, excitement, mass, age, temperature and exercise affect the heart.
The heart is two sided and has four chambers and is mostly made up of muscle. The heart’s muscles are different from other muscles in the body because the heart’s muscles cannot become tired, so the muscle is always expanding and contacting. The heart usually beats between 60 and 100 beats per minute. In the right side of the heart, there is low pressure and its job is to send red blood cells. Blood enters the right heart through a chamber which is called right atrium. The right atrium is another word for entry room. Since the atrium is located above the right ventricle, a mixture of gravity and a squeeze pushes tricuspid valve into the right ventricle. The tricuspid is made up of three things that allow blood to travel from top to bottom in the heart but closes to prevent the blood from backing up in the right atrium.
= The results that I have gathered from my experiment I have put into graph form. From my results I have found out that the more I exercise the longer I exercise the longer it takes for my pulse to return to normal, I think that I did not reach my potential maximum heart rate because the exercised was not strenuous enough for my body. I also discovered that when taking my pulse it takes a few seconds for the strong pulse to get back to the surface.
Investigating the Effect of Exercise on the Heart Rate Introduction For it's size the heart has the huge capacity of pumping large amounts of blood, in the average adult's heart beats 60 to 100 times a minute, pumps between 70ml and 100ml of blood with each beat, circulates 5 to 6 litres of blood around the body per minute and about 13 litres of blood per minute during vigorous exercise. The heart will beat more then 2.5 billion times during an average lifetime. This investigation will be looking at the effect of exercise on the heart rate. Aim The aim of this investigation is to find out how exercise affects the heart rate, using research & experimenting on changes and increases in the heart rate using exercise. Research â— The heart The normal heart is a strong, hardworking pump made of muscle tissue.
Saturated fat and cholesterol and an increased risk of heart disease. Fiber and a reduced risk of cancer. Fruit, vegetables and grain products that contain fiber and a reduced risk of heart disease.
Heart disease describes a range of conditions that affect your heart. Diseases under the heart disease umbrella include blood vessel diseases, heart rhythm problems, and heart defects. The major cause of this is a build-up of fatty plaques in the arteries. Plaque build-up thickens and stiffens the vessel walls, which can inhibit blood flow through the arteries to organs and tissues.
The Omega-3's are widely recognized for their role in heart health. Not only do these fatty acids help healthy hearts, they also benefit those with cardiovascular disease. Research has proved atherosclerotic plaque reduces with consistent consumption of omega-3's. Further, incidences of irregular heartbeats decline with these fatty acids; high blood pressure has been known to slightly drops as well.
Executing stretching activities helps out a lot too. Everybody stretch before they do any physical activities. Not stretching before a physical activity can result in pulling a muscle. Lifting weights is a great way to prevent heart disease also. “You can use weights, resistance bands, or your own body weight (yoga poses, for instance) for this.” ("Exercise for A Healthy Heart”). This should be done at least 2 times a week. The body should rest on other days for muscle recovery. Keep all of this up, and the heart will remain healthy, just as it should be.
