Turn up the volume Here's info. (expect for the pulmonary veins) that I couldn't find in my pamplet. I found out more terms because I looked at an old paper from anatomy class last year. Quotes from wikipedia chordae tendineae "The chordae tendineae, or heart strings, are cord-like tendons that connect the papillary muscles to the tricuspid valve and the mitral valve in the heart." papillary muscles "In anatomy, the papillary muscles are muscles located in the ventricles of the heart. They attach to the cusps of the atrioventricular valves (a.k.a. the mitral and tricuspid valves) via the chordae tendinae and contract to prevent inversion or prolapse of these valves." endocardium "The endocardium is the innermost layer of tissue that lines the chambers of the heart. Its cells are embryologically and biologically similar to the endothelial cells that line blood vessels." "myocardium (i.e., the actual heart muscle)" Epicardium "Epicardium describes the outer layer of heart tissue (from Greek; epi- outer, cardium heart). When considered as a part of the pericardium, it is the inner layer, or visceral pericardium, continuous with the serous layer." Interventricular septum "Interventricular septum (or ventricular septum, or during development septum inferius), abbreviated IVS, is the stout wall separating the lower chambers (the ventricles) of the heart from one another." pulmonary veins "The pulmonary veins are large blood vessels that carry blood from the lungs to the left atrium of the heart. In humans there are four pulmonary veins, two from each lung. They carry oxygenated blood, which is unusual since almost all other veins carry deoxygenated blood." When the heart was supposed to have evolved what parts (that are shown in this video/description) of the heart were not included at first? I got info. on the heart from a little pamplet that came with the model heart. "Human Biology Box Kit" "HEART" "Study the Structure and Function of Your Heart" I didn't quote it. I just got details mainly on what different functions are used for (ex. aorta is the exit for the blood). The pamplet explains it in different words. You can see the pamplet in the background a little bit on the couch. green=S.A node black=septum red=aorta yellow= Superior Vena Cava Inferior Vena Cava. It's supposed to be closer at the bottom of the heart, but I couldn't find it on the model. If I missed it and you see it on the model please tell me. light purple=bicuspid valve light blue= tricuspid valve gray=right ventricle dark blue=left ventricle dark purple=pulmonary artery light green=pulmonary veins right atrium=brown left atrium=dark green If I messed up on any of the parts of the heart please let me know.
