The heart is a solid organ about the size of a clench hand, found simply behind and marginally left of the breastbone. The heart siphons blood through the organization of arteries and veins called the cardiovascular framework.2. Myocardium - A. Cardiac muscle that makes up the bulk of the heart. Visceral pericardium- B. Smooth mesothelium covering the heart. Parietal pericardium- D. Flat mesothelium lining pericardial sac. Chordae tendinae - E. tethers that attach atrioventricular valves to the heart wall. Papillary muscles - C. Raised mounds of cardiac muscle. Cardiovascular muscle (additionally called heart muscle or myocardium) is one of three sorts of vertebrate muscles, with the other two being skeletal and smooth muscles. It is an automatic, striated muscle that establishes the fundamental tissue of the dividers of the heart. The twofold internal layer of the pericardium is known as the visceral pericardium. One layer of the visceral pericardium intently holds fast to the heart, and the other lines the inward surface of the external (parietal) pericardium. The interceding space is loaded up with pericardial fluid otherwise called the epicardium. The external layer of the pericardium is known as the parietal pericardium which is a conelike sac of fibrous tissue that encompasses the heart and the roots of the blood vessels. The pericardium has external and internal coats. The chordae tendineae conversationally known as the heartstrings are ligament looking like fibrous cords of connective tissue that interface the papillary muscles to the tricuspid valve and the mitral valve in the heart. The papillary muscles will be muscles situated in the ventricles of the heart. They join to the cusps of the atrioventricular valves through the chordae tendineae and agreement to forestall reversal or prolapse of these valves on systole.

fill in the blanks Blood that has circulated to the heart muscle itself also returns to the right atrium. Once blood leaves the cells of the myocardium, it flows into a system of cardiac veins, eventually flowing into the great cardiac vein, and then the coronary sinus. On this anterior view of the heart, locate the great cardiac vein and the coronary sinus (shown through to the back). Slide 14: Identify the two large veins that merge and flow into the superior vena cava: A._________________________________ and B._________________________________. (Note that unlike the arterial system, there are two veins, a right and a left, with this name.) Locate either the right or left brachiocephalic vein. Each is formed by the union of two slightly smaller veins. An C.___________________________ vein draining the head and a D.______________________ vein bringing blood back from the arm. Locate an additional vein draining blood from the head that flows into the subclavian vein, the…
isovolumetric contraction isovolumetric relaxation ventricular filling ventricular ejection closed rises S1 drops depolarize S2 The first phase of the cardiac cycle is . This is when a lot of blood is in the atria, which causes atrial pressure to be higher than the ventricles. The atrioventricular valves open, and blood moves from the atria to the ventricles. At the end of this phase, the atria contract to maintain pressure and blood flow into the ventricles. As blood leaves the atria, the pressure in the atria As blood enters the ventricles, the pressure in the ventricles Towards the end of this phase, the pressure in the ventricles will exceed the pressure in the atria. At this point, the heart enters the second phase of the cardiac cycle: At this point, the AV valves shut, and we hear . The atria repolarize and the ventricles (due to the QRS complex of the ECG), causing ventricular contraction. Although contracting, it is not yet moving blood into the arteries. All 4 heart valves…

Under the microscope, I can see a section through one of the chambers of the heart. The myocardium is thick and the endocardium is very thin.

What does the thickness of the myocardium tell you about this region of the heart? What is the valve called? What does it do? What other valve would you see in this area of the heart?
