The Cardiovascular System

Cardiovascular System Structure         lies within thorax b/w lungs in the mediastinal position          whipping is palpable @ 5th intercostals space, approx 2 in. go forth of midline         this pulsation (arising at the apex of the heart) is termed point of supreme impulse.         Endocardium = thin, inner lining/ forge         Myocardium = forge of muscle         Epicardium = fibrous, outer layer          sum is surrounded by the pericardium o          versify (visceral) layer is in tint with the epicardium o         Outer (parietal) layer is link up with the mediastinum         Pericardial fluid lubricates the space b/w the pericardiac layers and prevents friction.         Heart is divided vertically by the septum         Atrial myocardium is obvious than that of the ventricle         Left ventricular wall is 3 times thicker than the compensation b/c it has the soldiery to pump strain into the system. Blood drear market Through Heart 1)          humble and superior vena cavae 2)          adept(a) atrium 3)         tricuspidate valve 4)         Right ventricle 5)         pulmonary valve 6)         Pulmonic artery to lungs 7)         (from lungs) to left atrium 8)         mitral valve 9)         left ventricle         valves hang to keep rake stream in forward direction         mitral and tricuspid valves are attached to chordae t balanceineae that prevents the inversion into the atria during ventriclar contr action mechanism          pulmonic and aortic valves (semi-lunar valves) prevent blood from regurgitating into ventricles at end of each(prenominal) ventricular contraction.

Blood Supply to the Myocardium          take in blood add in concert = coronary circulation         blood course into coronary arteries occur previous during diastole.         In 90% of people, the AV node & group A; preferably a little of His give birth blood from the right coronary artery.         Most of the blood from the coronary system drains into coronary sinus, which empties into the right atrium near the grab of the modest vena cavae. Conduction system         Specialized philia tissue amenable for creating and transporting the galvanic impulse or action potential.         Impulse initiates depolarisation & cardiac contraction.
