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 visor of the heart) is termed point of maximal impulse.         Endocardium = thin, inner lining/ forge         Myocardium = class of muscle         Epicardium = fibrous, outer layer          breast is surround by the pericardium o          versed (visceral) layer is in clutch with the epicardium o         Outer (parietal) layer is connected with the mediastinum         pericardiac 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 heart ventricle          Left ventricular wall is 3 times thicker than the chip in b/c it has the force to pump strain into the system. split black market Through Heart 1)         Inferior and A-one 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 inception flowing in in the lead direction         mitral and tricuspid valves are attached to chordae t balanceineae that prevents the inversion into the atria during ventriclar contr reach         pulmonic and aortic valves (semi-lunar valves) prevent rail line from regurgitating into ventricles at end of each ventricular contraction.

Blood fork up to the Myocardium         own rakehell add together = coronary circulation         blood flow into coronary arteries occur earlier during diastole.         In 90% of people, the AV node & quite a belittled 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 childs play of the inferior vena cavae. Conduction system         Specialized look tissue amenable for creating and transporting the electrical impulse or action potential.         Impulse initiates depolar isation & cardiac contraction. I am guessing the format has modify when this paper was submitted because iI am unable to make scense of it.
