During diastole, when the heart is relaxed and filling with blood, the oxygenated blood from the left atrium will flow to the left ventricle. (lowest volume) Conversely, the inferior vena cava is located inferiorly, and it carries the deoxygenated venous blood from the lower body to the right atrium. Compare and contrast the structure of a cardiac muscle cell with that of a skeletal muscle cell. Please note that blue represents Deoxygenated blood. Blood will then flow from the right atrium, through the tricuspid valve, and enter the right ventricle. SA node depolarizes (location of autorhythmic cells that act as pacemaker of the heart) Greek God Hermes Facts & Mythology: Who was Hermes the God of? PARASYMPATHETIC STIMULATION: hyperpolarizes the membrane potential, slows depolarization by changing K+ permeability 8. End-systolic volume (ESV) - amount of blood in the ventricles after they have been "emptied" in the ejection phase. Left-sided heart failure occurs when the left ventricle, the heart's main pumping power source, is gradually weakened. what are the different types of leukocytes? open K+ channels 5. Explain why there is no resting membrane potential in the autorhythmic cells, how the pacemaker potential develops (fig. which of the following is NOT true for ventricular systole, T/F: the ventricles begin to fill during ventricular diastole, T/F: atrial contraction accounts for most of the ventricular filling, During which event of the cardiac cycle does aortic pressure reach its maximun, During which event of the cardiac cycle does the atria both relax and contract, During which event of the cardiac cycle do the atria and ventricles relax, T/F: the audible heart sounds are caused by the contraction of the atria ventricles, T/F: the P wave of the ECG coincides with ventricular filling. Blood in left atrium flows through left AV valve (mitral) into left ventricle. 4. Learn more about how the ductus arteriosus works here, and why its there for fetuses.
