Joselyn Bodnar Heart lab dissection 3/2/15 The Human heart has many complicated processes. Dissecting a sheep’s heart can help to provide an active‚ firsthand learning experience that allows to illustrate what has been previously heard and read. The sheep heart and a human heart share the same function and purpose‚ which is to keep the body alive by continually circulating blood around the body. Like a human heart‚ a sheep’s heart contains two atria and two ventricles. These four chambers

The endocardium is the innermost layer and lines the inner chambers and heart valves. Pericardial sac: The pericardial sac encases and protects the heart from trauma and infection. The pericardial sac has two layers which are the parietal pericardium which is the tough‚ fibrous outer membrane that attaches anteriorly to the

The right for homosexuals to marry has to be one of the most controversial topics of today’s time. The issue of gay marriage has been around since the turn of the century. In 1953‚ President Dwight Eisenhower signed Executive Order 10450‚ banning homosexuals from working for the federal government or any private contractor because they are considered “security risks”. In 1969‚ patrons of the Stonewall Inn riot for three days after an attempted police raiding to exterminate the neighborhood of “sexual

when this happens it is called a spontaneous mutation. Features of the disorder are not always present right away. Marfan features at birth or as young children can include serious conditions like aortic enlargement. Others have fewer features when they are young and don’t develop aortic enlargement or other signs of Marfan syndrome until they are adults. Some features of Marfan syndrome‚ like those affecting the heart and blood vessels‚ bones or joints‚ can get worse over time. The

~The 2 Semilunar Valves are the Aortic & Pulmonary Valves. They guard the bases of the large arteries issuing from the ventricles & prevent backflow into the associated ventricles. Each SL Valve is fashioned from 3 pocketlike Cusps & shaped roughly like a half-moon. The SL Valves open & close in response to differences in pressure. When the ventricles are contracting & intraVentricular pressure rises above the pressure in the aorta and pulmonary trunk‚ the SL valves are forced to

They work on a number of different products such as‚ flexible artificial discs to replace damaged cervical discs‚ better aortic valve replacements or prosthetic limbs. These products represent only a few numbers of the items that biomedical engineers work on. These products are also produced and designed by help of various electrical engineering duties.

EXTERNAL VIEW SURFACE VIEW OF HEART Position‚ Shape and Size of the Heart: The human heart is located between the lungs in the thoracic cavity (i.e. it is not situated on the left side of the chest). The heart is a hollow‚ fibro-muscular organ and is somewhat conical in shape. It is about the size of one’s fist‚ measures about 12 cm in length and 9 cm in breadth. Its weight is about 300 g in an adult. The heart is enclosed in pericardium (a double- layered membranous sac). It protects the
