Pulmonary Artery Vena Cava
1,945 wordsHeartthe human heart is a specialized, four-chambered muscle that maintains BLOOD flow in the CIRCULATORYSYSTEM. Located in the thorax, it lies left of the bodys midline, above and in contact with the diaphragm. It is situated immediately behind the breastbone, or sternum, and between the lungs, with its apex tilted to the body cavity's left side.

Coronary Artery Disease Beats Per Minute
2,046 wordsThe Normal Cardiac Cycle During each heartbeat, the two upper chambers (right and left atria) contract, followed by contraction of the two lower pumping chambers (right and left ventricles). This action is coordinated by the hearts electrical system. Normal electrical activation of the heart occurs in an orderly fashion. With each beat, the electrical impulse starts in the sinus (or sino atrial) node (in the right atrium). The impulse spreads through the atria, stimulating the atria to contract....

Divided Into Four Pulmonary Artery
3,525 wordsTheHheart Biology Histology The Human Heart. Abstract: Dorlands Illustrated Medical Dictionary defines the heart as the viscus of cardiac muscle that maintains the circulation of the blood. It is divided into four cavities; two atria and two ventricles. The left atrium receives oxygenated blood from the lungs. From there the blood passes to the left ventricle, which forces it via the aorta, through the arteries to supply the tissues of the body. The right atrium receives the blood after it has p...

Tricyclic Antidepressants Coronary Artery
4,629 wordsCardiac Location and Structures The heart is the driving force of the circulatory system, contracting about 70 times / minute to pump an adequate volume of blood with sufficient pressure to perfuse all body organs and tissues. The muscular organ, about the size of a clenched fist, weights from 300 to 400 g. It is located within the mediastinum of the thoracic cavity, above the diaphragm and between the lungs. This location subjects the heart? s activity to influence from all pressure variances d...
