Heart

The heart is the organ that pumps blood throughout the body and to your lungs. It supplies nutrients and oxygen to many tissues and removes the waste products and carbon dioxide. The heart has 4 chambers called the left and right atrium and the left and right ventricle. These are separated by valves that stop the backflow of the blood that may occur due to the pumping motion. The other two valves separate the entrances to the aorta and the pulmonary artery. The right side of your heart receives de-oxygenated

Your heart. You probably don't think about it often, even though it does so much. Sometimes you may ask why do we need our heart? What does our heart do? How do we keep our heart healthy? And how do we study our heart? These questions will be answered in this one article. Our heart is an organ that helps us stay alive. Without the heart we wouldn't have an organ in our body that pumps blood around the body. The heart does one thing: it forces blood around the body by all the parts of the heart working

How the Heart Works As everybody knows, the function of the heart is to pump blood throughout your body. You may be wondering how it does that though. I’ll explain how the heart works. The heart has two sides, the left and the right, which are separated by the septum. Each side has an atrium and a ventricle with valves separating them (to prevent blood from flowing backwards) (Atria and ventricles are chambers of the heart). They are also connected to various arteries (blood vessels that transport

in a seated position, and after exercising. The Heart is a hollow muscular organ that is cone shaped and it is located in the mediastinum in between the lungs (The Heart, Slide 3 2016). The heart is separated into two main divisions, the pulmonary circuit and the systemic circuit. The pulmonary circuit helps carry blood to the lungs from the heart for gas exchange and it is located in the right side of the heart. In the pulmonary circuit the heart fills with blood in the right atrium then it passes

Heart disease affects over five million Americans both male and female. Researchers have discovered that the differences in the growth of the heart and how diseases develop vary in males and females. Although both genders have many of the same risk factors, such as obesity, cigarette smoking, hypertension, and metabolic syndrome. Females are more likely to develop heart disease from elevated blood pressure due to menopause, having an autoimmune disease, or stress and depression. (Group, 2017) The

Congestive heart failure, also called heart failure or CHF, is one of the fastest-growing syndromes in the United States and worldwide. It is a condition with high hospitalization and high mortality rates as well as a compound medical regimen that significantly affects the patient’s lifestyle and that of their family. The term alone, “heart failure”, is enough to scare the bravest client and cause the rise of numberless concerns and questions. Patients may worry and exclaim, “Did my heart stop working

When the heart begins to fail, mechanisms are activated to compensate for the impaired function and maintain the cardiac output. The primary compensatory mechanisms are Frank –Starling mechanism, neuroendocrine responses including activation of the sympathetic nervous system and the renin- angiotensin-aldosterone system, and ventricular hypertrophy. Decreased cardiac output initially stimulates aortic baroreceptors, which in turn stimulate the SNS. SNS stimulation produces both cardiac and vascular

human heart, it is important to first understand its development. Initially, the fetal heart is a simple tube, consisting of just three layers and three specific areas. These primitive layers later develop into the myocardium and epicardium of the heart. The areas – cranial (head) end, caudal (tail) end, and bulbus cordis – eventually form the aorta and ventricles. Around the third week of pregnancy, the fetal heartbeat can be seen as a flicker on the ultrasound monitor. At this stage, the heart organizes

Gather Information and Identify Preliminary Issues Heart disease is the leading cause of death in both men and women in the United States.1 There’s been an increase in heart disease awareness among women in the United States from 34% in 2000 to 54% in 2009.2 This is due to public health efforts to educate women and increase awareness. The main issue in this case is figuring out a way communicate effectively by teaching women about their risk of heart disease and how the different risk factors can be

The heart and Circulatory System Coronary Circulation Coronary circulation is the circulation of blood in the blood vessels of the myocardium (heart muscle). Coronary arteries deliver oxygen-rich blood to the myocardium. Cardiac veins remove the deoxygenated blood from the myocardium. As the left and right coronary arteries run on the surface of the heart, they can be called Epicardial coronary arteries. These arteries, when healthy, are capable of auto regulation to maintain coronary blood flow
