Ventricles In The Heart Research Paper

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

If the heart and its chambers aren't formed correctly prior to birth, the healthy parts have to work all the harder.

Congenital heart defects (CHD) are birth defects that are considered the common in the United States. These defects affect a newborn child’s blood flow to and from the heart and sometimes can leave the heart lacking parts that make it necessary for the heart to do its job. According to the Centers for Disease Control and Prevention (CDC) (2014), 1 in 4 children born with a CHD is considered critical and will result in that child needing heart surgery or other similar procedures within the first years of its life. These CHD’s can range from Atrial Septal Defects, Coarctation of the aorta, Ebstien anomaly, Pulmanary artesia, Tetralogy of Fallot, Trancus Arteriosus, Hypoplastic Left Heart Syndrome, as well as many others (Centers for Disease Control and Prevention, 2014). The specific CHD that will be covered in detail will be the Hypoplastic Left Heart Syndrome (HLHS). HLHS accounts for nearly 960 congenital birth defects per year and

Your heart works tirelessly to pump blood between the chambers and your lungs, and out to the rest of your body. Over time, problems such as mitral valve disease, atrial fibrillation, and clogged coronary arteries can prevent the organ from performing its job. If such problems emerge, speak with your physician regarding an appropriate form of

The heart is a muscular four-chambered organ whose primary purpose is to pump blood throughout the body. The heart is the first functioning organ in the embryo. Its first pulsatile movements begin during the third week after conception. This early development of the heart is essential to rapidly growing embryo as a means of circulating nutrients and removing waste product. Most of the

Working in a facility where majority of the patients or residents have cardiac related health problems, I perform a shorter version of cardiac and peripheral vascular system assessments in day-to-day basis. Most of my residents have signs and symptoms of cardiovascular disease and daily monitoring is important. I have one resident in particular that I have been monitoring and regularly update the doctor of his status. He has congestive heart failure (CHF), COPD, and other co-morbidities. He has 4+ pitting edema to the lower extremities, elevated heart rate, and crackles to the lungs, which are the presenting symptoms of CHF (Jarvis, 2016). He is alert and oriented x3 with episodes of forgetfulness. I have to constantly reminding him to elevate

The heart is a very complex organ that is necessary for life. The heart is responsible for bringing oxygenated blood around the body. There are two main ways of transportation of blood around the body. The arteries go around the body and bring the oxygenated blood to various parts of the body. Once the oxygenated blood is utilized, it is brought back to the heart by the veins. The heart is broken into four major chambers that are separated by four major valves. There are two atria, which are located at the top of the heart, and two ventricles, which are located at the lower half of the heart. [5] The atria and ventricles are connected by the Mitral (bicuspid), tricuspid, pulmonary, and aortic valve. Each valve closed after the contraction to

As the heart uses a larger amount of blood, over time the left ventricles adapts and grows. This causes it to hold more blood, and ejects more blood per beat , even when your not exercising, at the same time certain muscles are contracting and relying on type two muscle fibers and the arteries expand each time the ventricles pump blood out from the heart. With that it helps increase the amount of oxygen you breath, which causes a quicker supply of oxygen and helps remove waste from your body.

Cardiomegaly is also referred to as an enlarged heart. Cardiomegaly is a descriptive term that is used to refer to the findings of an enlarged heart and is not considered a disease itself. This disorder can be caused by a number of different conditions including diseases of the heart muscle or heart valves, high blood pressure, arrhythmias, and pulmonary hypertension. Besides some of the different conditions it may also be accompanied by longstanding anemia and thyroid disease as well as other conditions. Treatments and prognosis are determined by the different causes of an enlarged heart. When it comes to the signs and symptoms of cardiomegaly most often, cardiomegaly causes no real types of symptoms. If an enlarged heart is unable to circulate

Heart is a crucial organ in human body and if the heart does not work properly, the person will die. The human heart is a muscular organ which pumps blood all over the body. In human, the heart size is roughly same as the size of a large fist (Lewis 2016). Heart failure can happen for anyone. However people with anemia, hyperthyroidism and an overactive or underactive thyroid disease are at higher risk (Moore; Roth 2015). Artificial heart can replace as real heart which can save many people from dying while they are waiting for heart transpose. In the past, the majority of artificial hearts have been used for people who waiting for heart transplant whereas, some people use artificial heart as permanent use (Tucson 2014). It is extremely important

Heart failure is a condition where the heart is unable to pump insufficient amount of blood to supply the rest of the body. This is a consequence of ventricular remodelling. Ventricular remodelling is a term that refers to alterations in structure, shape and function of the left ventricle. (1) The activation of neuro-hormonal systems such as RAAS and the sympathetic nervous system are predominantly linked to the pathophysiology of heart failure. Therefore, interrupting this system is vital to delaying the progression of heart failure. (2)

Prevalence of elderly worldwide is rapidly accelerating from 461 million people aged over 65 years in 2004 to an estimated 2 billion people by 2050 (1).

Anatomy is one of the oldest branches of medicine, with historical records dating back at least as far as the third century BC . Cardiac anatomy has been a continually explored topic throughout this time, and there are still publications on new facets of cardiac anatomy being researched and reported today. One of the fundamental tenets of the study of anatomy has been the description of the structure based on the universal orientation, otherwise termed the anatomic position (Fig. 2.1 ). The anatomic position depicts the subject facing the observer and is then divided into three orthogonal planes. Each plane divides the body or individual structure within the body (such as the heart) into two portions.

6. Automaticity – ability of heart to beat spontaneously and repetitively without external neurohormonal control. The heart is capable of beating outside the body, given proper laboratory conditions. Automaticity is evidently linked to fluid and electrolyte balance rather than to nervous system control.
