damage to the heart. "Stable" angina occurs repetitively and predictably while exercising and goes away with rest. "Unstable" angina results in unusual and unpredictable pain not relieved totally by rest‚ or pain that actually occurs at rest. 3. Aortic dissection: The aorta is the main artery that supplies blood to the vital organs of the body‚ such as the brain‚ heart‚ kidneys‚ lungs‚ and intestines.

An electrocardiogram machine translates the heart’s electrical pattern into lines that specific professionals can read

into the left atrium. Oxygenated blood then pumps through the mitral valve and into the left ventricle. The left side of our heart contracts the strongest to send blood out the left ventricle and through the aortic arch on its way to all parts of our body. Our blood will then move through the arteries‚ then through capillaries‚ and then return through our veins. Deoxygenated blood will then return to the heart. The valves of our heart are located

system circuit‚ starts via the left atrium and passing the mistral valve down into the left ventricle. The ventricle will then contract shortly after the atria have started relaxing and followed by the closing of the atrioventricular valves‚ so blood does not back wash into the atrium. Pressure will becoming higher in the left ventricle allowing ventricular systole ’s second phase to begin by forcing blood through the aortic semi lunar valve up into the aorta so blood may reach the rest of the tissues

chamber) pumps the blood away from the heart. The atria and ventricles chambers are separated by four main valves called the atrioventricular (two valves)‚ pulmonary‚ and aortic valves. These valves help create the heart sounds often referred to as “Lub” and ‘Dub”. Thus‚ the Lub sound is the closing of the atrioventricular valve‚ and the Dub sound is the closing of the pulmonary and aortic valve. In this lab‚ we became familiar with the functions of the heart. We also determined

CVP and its normal waveform1 - 2 : It is a technique used to measure existing pressure at the junction on CVC and the right atrium. To measure the pressure they used the central venous catheter that inserted on right jugular vein. This technique used for evaluation the cardiac function in ill patients. In addition‚ it can used for diagnosis purposes such as heart failure and fluid resuscitation. The relationship between cardiac function and venous return used for determination of heart failure

left ventricle carries oxygenated blood from the left atrium via the mitral valve to the aorta via the aortic valve. Right ventricle: The right ventricle carries deoxygenated blood from the right atrium via the tricuspid valve to the pulmonary artery through the pulmonary valve and pulmonary trunk. Left atrium: The left atrium carries oxygenated blood from the pulmonary veins to the left ventricle through the mitral valve. Right atrium: The right atrium carries deoxygenated blood from the superior

The myocardium (cardiac muscle)‚ is the thickest section of the heart wall and contains cardiomyocytes‚ the contractile cell of the heart. 2. What part of the heart is the pacemaker and why? The SA Node is located in the right atrium of the heart. It is made up of a group of cells (myocytes) positioned on the wall of the right atrium‚ at the center of the heart and near the entrance of the
