Danielle Rollins Cardiovascular Physiology Activity 1 1) Explain why the larger waves seen on the oscilloscope represent ventricular contraction. The ventricular contraction is when the blood is sent through the whole body as opposed to the atrial contraction that sends the blood to the heart and lungs. 2) Explain why the amplitude of the wave did not change when you increased the frequency of the stimulation. (Hint: relate your response to the refractory period of the cardiac action potential)

(ventricular diastole‚ atrial systole etc.) Ventricular diastole is the period during which the ventricles are relaxing‚ while atrial diastole is the period during which the atria are relaxing. Atrial systole represents the contraction of myocardium of the left and right atria. Atrial systole occurs late in ventricular diastole. One force driving blood from the atria to the ventricles is the decrease

Parts and Functions of the Eyes Cornea : The cornea is the outer covering of the eye. This dome-shaped layer protects your eye from elements that could cause damage to the inner parts of the eye. There are several layers of the cornea‚ creating a tough layer that provides additional protection. These layers regenerate very quickly‚ helping the eye to eliminate damage more easily. The cornea also allows the eye to properly focus on light more effectively. Those who are having trouble focusing their

What part of the trace shows the refractory period? The atrial contraction is the part of the trace that shows the refractory period. 8. Does summation occur? No‚ summation does not occur. 9. Why is it important that summation not occur in heart muscle? Summation would increase the Heart muscle contractions
