Mitral valve

The Human Heart: A General Description The heart is the main organ of the cardiovascular system in the human body. Its primary function is to pump oxygen- and nutrient-rich blood throughout the 60,000 miles of blood vessels that make up this system ("Heart, 2015"). About the size of a clenched fist, the heart is located in the middle of the chest, between the lungs and nestled behind the ribcage. It lies a little to the left of the sternum. The shape of the heart is reminiscent of an upside…

Alex was also diagnosed with a form of autism that limits his social interactions with other people. He still receives education through a hospital…

1. What is the function of the septum? of the left side of the heart? of the heart valves? The function of the septum is to separate the two sides of the heart. The left side of the heart takes in oxygen rich blood, the the valves prevents back flow of blood to the heart. 2. What is the function of the right side of the heart? the function of the right side of the heart is to pump deoxygenated blood into the pulmonary veins around the lungs. 3. What are the major blood vessels that bring…

What is Cardiovascular Disease? (Heart & Blood Vessels) A heart and blood vessel disease (heart disease) is multiple problems within the heart one major one is called atherosclerosis. Atherosclerosis is a heart condition caused by a substance called plaque that build up on the walls of the heart arteries. This plaque buildup can narrow the hearts arteries making it harder for blood to flow through. When this problem starts to happen it can cause clotting which is able to stop blood flow and…

Prosthetic Heart Valves for Pediatric Patients Madeline Setear, Biomedical Engineering, University of Rhode Island BME 181 First Presentation, March 6th, 2017 Abstract— Heart valve failure makes up a significant portion of Cardiovascular diseases. Heart valves fail when they are damaged and deteriorating or when they have congenital deformities. Heart valve replacement methods have improved greatly in the past decade. Currently, Mechanical and Biological Heart valve prosthesis exist but both…

The Mechanics of the Heart An electrocardiogram, or EKG/ ECG, is a non-invasive test that measures the electrical activity of the heart and its electrical patterns. An electrical signal is sent through the heart to produce contractions that move the blood. This is what an EKG measures. In total that test may take from five to ten minutes and are ordered by a doctor to examine the heart more close. An EKG is done while the patient is lying down completely still (in order to reduce artifact or…

the breastbone. It has two major coronary arteries, electrical impulses, four chambers, and four valves to help the blood flow one way. Deoxygenated blood enters the right atrium from the superior and inferior vena cava. When the right atrium contract the blood flows through the tricuspid valve and into the right ventricle. When the right ventricle contracts the blood passes the pulmonary semilunar valve, into the pulmonary artery, and the blood is going to the lungs. The blood goes through a…

first trimester to become the heart. The heart is made up of four chambers: the right atrium, the left atrium, the right ventricle, and the left ventricle. There are two atrioventricular valves: the tricuspid valve in the right side and the mitral valve in the left side. There are also the pulmonary and aortic valves that originate from the right and the left ventricles. The heart is located in the mediastinum. During embryonic development, oxygenated blood from the placenta flows into the right…

Pulse pressures that exceed 40 mm Hg, like in the case of Gerhardt, is a risk factor for cardiovascular diseases such as mitral valve regurgitation or valvular pulmonic stenosis.2,3 The presence of the soft mid-systolic murmur near the upper left sternal border was also suggestive of valvular pulmonic stenosis.3 However, Gerhardt’s prolonged PR interval of 0.62 seconds, bradycardia…

cava 10, this blood enters the right atrium 11. Now the right atrium contracts pushing the blood into the right ventricle 1 through the tricuspid valve. As the ventricle is filled the tricuspid valve closes to prevent any back flow of the blood. The right ventricle contracts forcing the blood to enter into the pulmonary artery 2 through the pulmonary valve. The pulmonary artery extends into both of the lungs where the deoxygenated blood is replenished with oxygen and is send back to the heart…
