Cardiovascular diseases are potentially chronic illnesses that affect many individuals of all ages across the world. Heart disease is a condition that consist of the narrowing or blockage of blood vessels in the human body that leads to myocardial infarctions, chest pain, and even strokes. Concerns about the effects of heart conditions have inspired scientific research to help address the problem. The article, “Heart Therapy” by Gabor Rubanyi examines a different approach that can be used to prevent serious heart problems. The article is based on the premise that people can be at risk of developing blood clots or a thick buildup of plaque in the walls of the arteries that can block an individual’s arteries leading to a heart attack and in other severe cases, death. Rubanyi is a physician, and co-founder of Angionetics that intends to use gene therapy to grow new blood vessels in the heart. This paper will provide a summary and critique of the thoughts and ideas posited by Rubanyi.
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
In Falcon’s report “Heart Disease” he anatomically describes the heart as “a fist sized organ located in the lower left quarter of the chest…[consisting] of four chambers: the right and left atria on top and the right and left ventricles at the bottom” (Falcon). While the heart is one of the smaller organs in the body, it has an enormous and important job to do; deliver nutrient carrying blood to the tissues in the human body. In people with heart disease, the heart is impeded and cannot efficiently deliver nutrients and oxygen to structures such as our muscles or our brain. This is one of the reasons that heart disease is so deadly; when our body structures are deprived of necessary nutrients, they begin to breakdown. The term “heart disease” encompasses a wide variety of
The heart is one of the most important organs in the body. The heart is responsible for pumping blood throughout the human body supplying the tissue with oxygen and nutrients and removing carbon dioxide and waste. If the heart does not supply blood and oxygen to the organs and tissues, they will die.
The heart is what keeps the human body running. From the very first time someone presses their head up against their mothers chest or feels their own heart beat, they know that the pulse they feel means something important. It’s the rhythm that lets us keep on living. It’s strange to think that before I read this book, I barely knew anything about this absolutely vital organ in my body. Now, I probably know more history about the human heart than I ever thought I’d know. This book went totally in depth about the history of the human heart, and how modern medicine knows what it knows about this vital organ. It weaves history and information about the heart together in a way that keeps you interested until the last page, which is something I
Coronary artery disease remains number one killer of the western civilization despite 40 years of aggressive drug and surgical interventions (Esselstyn). Usually, pharmaceutical drugs, such as statin, are given to try to slow the progression, but may provide uncomfortable side effects. In fact, the majority of patients discontinue statins within 1 year of treatment initiation (Maningat). Furthermore, surgery is performed to circumvent clogged arteries and literally bypass the symptoms. In the last year, 500,000 coronary bypass procedures were performed (Swaminathan et al). However, these surgeries can have significant risks, including the potential to cause further heart damage, stroke, and brain dysfunction. Thus, it is evident that these way of treatments may not be enough on its own, and that getting to the
The heart is a very strong muscle that has one major job. The heart’s job is to pump blood throughout the entire body. The heart is made up of 4 chambers, and 4 valves. There is the right and left atrium, and a right and left ventricle. The atriums are the superior chambers, and the ventricles are inferior chambers. The left ventricle is the most important, because that is where the blood travels through to go to the aorta, and eventually the rest of the body (Taylor 2015).
heart from the body by the veins and its purpose is to keep us alive
The heart is an organ that pumps blood from the body and maintains all the organs functioning to keep one alive; when one of the arteries that receive blood is blocked it can cause a heart attack or myocardial infarction (MI). “During a heart attack, the heart muscle (the myocardium) is damaged, and part of it die from lack of blood” (book, p. 429).
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
Every day, the approximately 5 liters of blood in your body travel many times through about 97,000 kilometers of blood vessels that branch and cross, linking the cells of our organs and body parts. From the hard-working heart, to our thickest arteries, to capillaries so thin that they can’t be seen with the naked eye, the cardiovascular system is one of the most important systems in our body.
The heart is a complex yet delicate organ that operates the body on a regular basis. Without the heart the circulation system within the body would cease to exist; therefore, we would cease to exist. As with everything that is complex and works around the clock there are certain issues that can arise for example, atrial fibrillation. Atrial fibrillation is the result of an irregular or fast heartbeat this will often cause an inadequate circulation throughout the rest of the body. The atrium of the heart will not sync up to the ventricles causing an irregular or fast heartbeat.
The human body is a very complex organism composed of different types of systems and functions. All the functions that each system has, is what makes possible for the body to obtain life. One of the most important systems in one’s body is the circulatory system, where the heart, the lungs, and the blood vessels work together to form the circle part of the circulatory system. The pumping of the heart forces the blood on its journey. The body’s circulatory system really has three parts: pulmonary circulation, coronary circulation, and systemic circulation. Each part must be working independently in order for them to all work together. However, when one of the parts of the circulatory system does not
In today’s society, people are gaining medical knowledge at quite a fast pace. Treatments, cures, and vaccines for various diseases and disorders are being developed constantly, and yet, coronary disease remains the number one killer in the world.
Blood is one of the most vital components of the human body. The blood carries many functions such as to supply oxygen to the bodies tissues, remove metabolic waste products, regulate our core temperature as well as fighting infection and foreign bodies (Glover, 1997). The cardiovascular system is composed of the heart and its vessels. The heart is an involuntary muscle which receives blood to the atrias, which is then pumped via the ventricles. The vessels are composed of three main types. Arteries, veins and capillaries; all which transport blood throughout the entirety of the body. The constant action of both the vessels and heart ensure that the body receives a continuous supply of blood, keeping us within our homeostatic limits.
The heart is what keeps all living breathing species alive, animals or humans. If the heart was to shut down but the nervous system continued and was active, it would not matter. The entire body would shut down because once the supplier no longer delivers what is needed; organs will no longer function correctly, therefore causing irreversible damage. Arteries are what carried the rich oxygenated blood from the heart to the rest of the organs throughout the body. The Veins are what bring back the carbon dioxide blood to the heart. It then has to be put through a cycle so that it can be shipped back out. Blood travels from the right atrium through the tricuspid valve, to the right ventricle. From there, it is pumped to the lungs, the oxygen-rich blood goes to the left atrium and then through the mitral valve to the left ventricle where it goes to the aorta to be pumped around the body (Colombo 7). What looks to be a complicated process that would take hours or minutes is actually done in a matter a seconds.
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.
