Heart

Open heart surgery can be real painful on a family, just as it is to the person having it. My father had to undergo this procedure, and might have to undergo it again. This was a devasting time for my family and myself. This occurred almost two years ago. The evening before my father’s surgery they had him take a shower or bedside bath. They told him to use a special soap on his chest and legs. This special soap kills the bacteria on your skin and helps to prevent infection after surgery. The

Heart arrhythmia is a term that refers to a large number of conditions that are caused by abnormal electrical activity within the heart's nodes or sections. Arrhythmias may be medical emergencies that result in cardiac arrest or they may simply be an abnormal awareness of one's heart-beat. Palpitations, for example, are not usually life-threatening. They may be brought on by stress, hormones, exercise, medications or anxiety. Anxiety disorders are characterized by frequent palpitations and may

function of the heart. The heart is an organ that pumps blood throughout the body. The body relies on the heart because the heart has to pump blood to the body. The heart receives blood from the body, which it then sends to the lungs. The lungs give oxygen to the blood. That blood then goes back to the heart, where the heart pumps it back to the body. The body needs oxygen because it needs oxygen for energy, which is why the heart is very important for the body. Without the heart, there is no blood

The ventricles of the heart connected so intimately to each other in driving the function of the whole heart were therefore thought to have very similar function. Moreover, the proteins of LV and RV originate from the same genes (Myl6 for ELC, MYH6 and MYH7 for HC, MYL2 for RLC, MYL3 for LC). Only, recent advances shed light on their dissimilarities at varying levels of genetic, proteomic 5, force studies etc 14, 24,38. Much of the differences in the LV and RV are explicable from their different

The function of the heart is to pump blood around the body. It is a hollow muscle and can be found between the lungs in the mediastinum and behind the sternum and between the second and sixth ribs. It is the size of a fist and has four chambers. The upper chambers are the left and right atria, with the bottom chambers the left and right ventricles. The heart consists of several layers: the pericardium (outer protective covering of fibrous tissue), the epicardium (made up of epithelial cells and secretes

(Points : 1)        Right

THE HEART The heart is a muscular organ about the size of a closed fist that functions as the body’s circulatory pump. It takes in deoxygenated blood through the veins and delivers it to the lungs for oxygenation before pumping it into the various arteries (which provide oxygen and nutrients to body tissues by transporting the blood throughout the body). The heart is located in the thoracic cavity medial to the lungs and posterior to the sternum. On its superior end, the base of the heart is attached

The heart is an organ that can be seen as the center of life for an organism. It function is simple but of great importance as it has to pump blood through the organism (Unknown et al., 2017). In mammals and land based organisms the heart pumps deoxygenated blood to the lungs where it then moves back to the heart and is pumped to the outer most extremities, muscles and all other organs (Campbell et al., 2008). The heart is a striated muscle but unlike other striated muscles it is involuntarily

Heart murmurs are swishing or whooshing sounds created by turbulent blood with each heartbeat. This sound is usually observed through auscultation of the heart with a stethoscope. Many times, this sound is indicative to underlying cardiac abnormalities. However, the sound can be benign and many live without incident and asymptomatic. Abnormalities to the structure of the heart may be the main cause. These malfunctions can be congenital in nature or may come with stress on the heart and valves. Common

The heart is one of the earliest differentiating and functioning organs of the human body. In human embryos, the heart will develop from the mesoderm and begin to beat in a little over three weeks.1 When the heart is fully formed, it will be about the size of a large fist and will serve as the circulatory pump for the body.2 In this role it aids in pulmonary circulation where blood is sent to the lungs to be oxidized and in systemic circulation where blood is sent throughout the body. This process
