The Human Heart : The Most Important Organ In The Human Body

Did you know the your heart is the size of both of your hands clapped together. The heart is a organ that keeps you alive. It is in your chest protected by the rib cage. The purpose of this paper is to summarize information about the heart, explains how it works, and discuss its purpose.

Tachycardia: Tachycardia typically refers to a heart rate that exceeds the normal range for a resting heart rate. When the heart beats rapidly, the heart pumps less efficiently and provides less blood flow to the body and the heart. The rapid heartbeat increases the workload and oxygen demand of the heart. Problems will occur with the heart as tachycardia persists over time. The heart is maintaining less oxygen, which will lead to an MI due to death of the myocardial cells. Patient will start to have angina because of this. Tachycardia is noted in many diseases and disorder like: fever endocarditis, anemia, HTN, pericarditis, abnormal heart impulses, anxiety, older age, sleep apnea, COPD, electrolyte imbalances, and many more.

Introduction: Heart rate is the measure of beats the heart pumps per minute. A resting heart rate for a normal healthy individual is between 60-100. If the resting heart rate is above 100 it could be a result of Tachycardia and if it is below 60 it could be a result of Bradycardia. Heart rate can fluctuate due to over all health, whether you active or sedentary, or through certain substances we put in our bodies.

The human heart pumps around 2,000 gallons of blood to all areas of the body. “In a 70 year lifetime, an average human

Heart rate is defined as the number of contractions the heart carries out in one minute. Blood pressure has two measurements: systolic blood pressure, or the pressure exerted on the artery walls during cardiac systole, and diastolic blood pressure, or the pressure exerted on the artery walls during cardiac diastole (American Heart Association, 2014). Blood pressure is measured with a sphygmomanometer in millimeters of mercury, or mmHg, whereas heart rate is measured using a variety of tools and is recorded in beats/minute.

Almost 80% of people die from heart disease. The only way to know your level of risk is to be assessed by a healthcare professional and to be checked for factors such as your blood pressure, cholesterol and glucose levels, waist measurement and BMI. Once you know your overall risk, agree with your healthcare professional on a plan for specific actions you should take to reduce your risk for heart disease and stroke. The Circulatory System is made up of three main parts: The heart, the blood vessels and the blood. Sometimes the watery fluid called lymph and the vessels that carry it are considered to be part of the Circulatory System. The heart is a special pump that pumps the blood around the body. The purpose of this paper was to summarize information about the heart, explain how it works, and discuss its purpose. It was said that the heart evolves through several different stages inside the womb, first resembling a fish's heart, then a frog's, which has two chambers, than a snake's, with three, before finally adopting the four-chambered structure of the human heart. I also told you how the heart works. When the heart contracts, the chambers become smaller, forcing blood first out of the atria into the ventricles, then from each ventricle into a large blood vessel connected to the top of the heart. Now the purpose of the heart is the size of its owner's clenched fist, the organ sits in the middle of the chest, behind 1the breastbone and between the lungs, in a moistened chamber that is protected all round by the rib cage. It can also be easy to fix the heart. The only way to know your level of risk is to be assessed by a healthcare professional and to be checked for factors such as your blood pressure, cholesterol and glucose levels, waist measurement and BMI. The heart is very important for your

Each day, your heart pumps nearly 2,000 gallons of blood. Over the course of an average lifetime, it will beat over 3 billion times. It is slightly larger than a clenched fist, and is located behind the sternum, between the lungs.

The purpose of this lab is to understand how to measure the heart rate and blood pressure of an individual by the appropriate method. It is important to know how to take these measurements accurately in the healthcare or fitness professions. In this lab, the heart rate was measured by a stethoscope over the chest, and with the middle and index fingers for the carotid and radial arteries. For blood pressure, a sphygmomanometer and stethoscope were used to identify the Korotkoff sounds that indicate the systolic and diastolic pressures. Risk factors such as heart disease and high blood pressure can be discovered through the

-Heart rate is the number of times a person 's heart beats per minute. When you are preforming a type of exercise that will increase your heart rate, then your heart will pump blood all around your body faster and especially to muscles that are working the most because they require the most oxygen because of the intensity they are working at. It is vital to take your resting heart rate and the normal heart rate is 60-100bpm. For example, our cardiovascular exercise was cycling on a stationary bike for 20 minutes at a reasonable pace and this will depend on whether your heart rate will increase at a slow, fast or steady rate. However, the first 5 minutes we cycled at a very fast pace in order for your heart to pump more blood all around the body and to the required muscles in order for them to work harder. But the response is that the heart rate levels off, which means that it becomes steady so that after beginning the exercise and you’re like 5 minutes into it then your heart rate will stay the same or increase by little bits unless you change the intensity all the time which is not required when doing cardiovascular exercises.

Your heart rate, also known as pulse, is the number of times your heart beats or contracts per minute. Due to the variation of the effects on hearts, rate fluctuates from person to person. Common effects of heart rate

The heart is one of the main organs of the human body which is responsible for pumping blood throughout the body including the brain and other organs through the circulatory system.

The hearts role is to pump oxygenated blood to every cell in the body by having a continuous beat. Throughout time the heart has created mystery, however current technology has solved most of the mystery, there still remains an enchantment and eagerness to learn more.

In our world organisms occupy a sliding scale of complexity. On one hand we have the single cell organisms, where all necessary functions for their life are carried out within that one cell. At the other extreme we have extremely complex multicellular organisms, of which humans are perhaps the cardinal member. Obviously, with increased capacity comes increased abilities. Complex organisms are able to manipulate their environment to a greater extent then their simpler cousins. While this has a lot of advantages, it also presents interesting biological problems. With the increased complexity multicellular organisms must have systems to deliver nutrients, signaling molecules, and biochemical building blocks to every cell. In

The heart rate is a measurement of how many times the heart beats in a minute. Physically fit people tend to have a lower heart rate and during intense exercise tend to have lower rates as well. A decrease of heart rate at both rest and at fixed intensity of sub-maximal exercise [7] occurs a few months after an exercise program is begun. One’s heart rate reflects the amount of work the heart must do to meet an increase of demands of the body when engaged in activity. Heart Rate tends to increase proportionally with intensity oxygen uptake [16].

In the article, Rubanyi begins by explaining to the reader the important function of the human heart. The author clarifies that the heart is the most important organ in the human body that pumps oxygen rich blood to the entire body via the circulatory system. In fact, the heart beats about 100,000 times, and pumps about 2,000 gallons of blood in a single day through a network of blood vessels. However, the circulation of blood flow can be disrupted through a blockage caused by a blood clot or
