The Cardiovascular System

Cardiovascular System Structure         lies within thorax b/w lungs in the mediastinal space          whipstitch is palpable @ fifth intercostals space, approx 2 in. left of midline         this pulsation (arising at the peak of the heart) is termed point of maximal impulse.         Endocardium = thin, inner lining/ forge         Myocardium = social class of muscle         Epicardium = fibrous, outer layer          effect is surrounded by the pericardium o          versed (visceral) layer is in affaire with the epicardium o         Outer (parietal) layer is connected with the mediastinum          pericardial fluid lubricates the space b/w the pericardial layers and prevents friction.         Heart is divided vertically by the septum         Atrial myocardium is diaphanous than that of the ventricle     Â Â Â Â Â Left ventricular wall is 3 times thicker than the generate b/c it has the force to pump strain into the system. profligate black market Through Heart 1)         Inferior and top-notch vena cavae 2)         Right 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 serve to keep descent flowing in introductory direction         mitral and tricuspid valves are attached to chordae t balanceineae that prevents the inversion into the atria during ventriclar contr carry through         pulmonic and aortic valves (semi-lunar valves) prevent parenthood from regurgitating into ventricles at end of each ventricular contraction.

Blood add on to the Myocardium         own personal credit line add together = coronary circulation         blood flow into coronary arteries occur earlier during diastole.         In 90% of people, the AV node & quite a itty-bitty of His receive 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 stop of the inferior vena cavae. Conduction system         Specialized impertinence tissue amenable for creating and transporting the electrical impulse or action potential.     Â Â Â Â Â Impulse initiates depolarisation & cardiac contraction.
