Describe the events of a cardiac cycle based upon contracting and relaxation phases. Describe the activity of each chamber during cardiac systole and cardiac diastole. Be able to relate the electrical activity of the heart (depolarization, repolarization) to the corresponding electrical activity depicted on a typical ECG/EKG tracing. Label and define the waves. Trace the depolarization pathway through the intrinsic conduction system components. Compare and contrast cardiac and skeletal muscle contraction.

Describe all the events (steps) that occur during a cardiac cycle for mammals (organisms with a double circulation), as well as the opening and closing of all heart valves and the signals arising from the SA and AV nodes How does this cycle contribute to metabolic homeostasis for our cells, and what is the purpose of the valves?

Describe the physiological events occurring in the heart muscle represented by each ECG component (the P wave, QRS complex, and T wave). Why does the QRS complex have the largest amplitude?

describes the events of the cardiac cycle align with the heart sounds and the components of an ecg. When you inhale, does your chest expand because your lungs inflate, or does lungs inflate because your chest expands? Explain what causes air to move in and out of the lungs. Our body is pretty amazing at protecting itself. Compare and contrast: - the innate vs. adaptive immune systems - the two types of adaptive responses Your older sister is in training...

Which of the following best describes the events of the cardiac cycle? A. ventricular diastole - atrial diastole - atrial systole B. systole - diastole C. atrial systole - ventricular systole - diatolediastole D. dub - lub - lub

Using the Wigger's diagram, explain the relationship between electrical and mechanical events during the cardiac cycle (mechanical events are actions of chamber and valves and involve pressure, flow and volume of blood).

Beginning with all chambers of the heart in the "relaxed" phase, describe the cardiac cycle in mammals, with systole and diastole of the atria and ventricles. For each time point in the cycle you select, state the following: Whether the atria and ventricles are contracting or relaxing Whether the AV valves and semilunar valves are closed or open Whether the pressure in the atria and ventricles is high or low

Explain the steps of the cardiac cycle
