Feedback or suggestions for future topics? If this were the field over the entire surface, what would be the electric potential of a point on the surface? During systole, when the heart (specifically the ventricles) are contracting, deoxygenated blood from the right ventricle will be pumped forward from the right ventricle to the main pulmonary artery. 22. Endocardium The deoxygenated blood will then exit the right ventricle, travel through the pulmonary valve, and enter the main pulmonary artery to ultimately be delivered to the lungs to become oxygenated. Flashcards. T/F: Action potentials are carried by the Purkinje fibers from the bundle branches to the ventricular walls. There are three major branches of the aortic arch: the brachiocephalic artery, the left common carotid artery, and the left subclavian (literally "under the clavicle") artery. Isovolumetric relaxation -muscles recieve 27% at rest, stroke volume x heart rate = cardiac output, heard first and is made by the tricuspid and mitral valve closing between atria and ventricles, refereed to at S1 sound, (heard loudest at apex of heart), heard second and is shorter and higher pitched, is caused by the semilunar valves (pulmonary and artery closing) S2 sound, Non-invasive, device used to record the electrical activity of the heart, that causes the contraction (systole) and the relaxation (diastole) of the atria and ventricles during the cardiac cycle, What is the baseline or isoelectric line of ECG or EKG, the flat line that separates the various waves and is present when there is no flowing in the heart.

Moosmosis, Endocarditis vs Myocarditis vs Pericarditis Causes, Symptoms, Diagnosis, Treatment, and Prognosis [MCAT, USMLE, Biology, Medicine] Moosmosis. T/F: The heart separates the pulmonary and systemic circulations and ensures better oxygenation of the blood flowing to the tissues, T/F: The valves of the heart allow blood to flow in different directions through the heart based upon the pressure differences from the pulmonary and systemic circulations, T/F: The rate and force of heart contractions change to meet the metabolic needs of the tissues which can vary based on different conditions. Cover the systematic and pulmonary circulations in order, starting from the left ventricle. 23. This is why the left ventricle needs to pump the blood by generating more force during contraction to do this. The period of time that begins with contraction of the atria and ends with ventricular relaxation is known as the cardiac cycle.The period of contraction that the heart undergoes while it pumps blood into circulation is called systole.The period of relaxation that occurs as the chambers fill with blood is called diastole.Both the atria and ventricles undergo systole and diastole, and it is . Excellent article on blood flow steps!! Pulmonary Vein 9. F. benzyl hydride, G. cyclohexane, H. hexane, I. Step 6 involves the main pulmonary artery, also known as the pulmonary trunk.

The right ventricle has to pump blood farther than the left. Compare and contrast the duration of the action potential and refractory period of heart vs. skeletal muscle (fig. If stroke volume is not the same in each ventricle, edema may result. From the lungs, oxygenated blood is returned to the heart through the pulmonary veins. Gap junctions pass on the AP from 1 contractile cell to the next AV valve The specialized cell junctions between myocardial cells are called __________. This is where the aortic pressure surpasses the pressure in the ventricles, causing the SLV to close, which also causes the "dub" sound. Compare and contrast the pulmonary circulation with the systemic circulation (from where to where; components - heart chambers, valves, arteries, veins, capillaries; organs served by each). refractory period: period of time following an AP during which a normal stimulus cannot trigger 2nd AP What if it's illuminated by blue light? - sustained AP helps prevent tetanus AP & refractory period of heart: long AP & refractory period end almost simultaneously 20.
