Pulmonary blood flow in normal subjects is the same as cardiac output, the amount of blood pumped by the heart per minute. Stroke volume is the volume of blood pumped per beat. The ability of carbon monoxide to diffuse into the blood is a standard clinical test of the integrity of the alveolar membrane and its surrounding capillary blood supply.
The cardiac muscle is capable of which of the following? Which of the following is true of the cardiac action potential? The cardiac action potential is longer than the skeletal muscle action potential.
The main anatomical difference between the frog heart and the human heart is that the frog heart has You correctly answered: Experiment Results Predict Question: When you increase the frequency of the stimulation, what do you think will happen to the amplitude height of the ventricular systole wave?

The amplitude will not change. If you deliver multiple stimuli 20 stimuli per second to the heart, what do you think will happen? Watch the contractile activity from the frog heart on the oscilloscope.
Enter the number of ventricular contractions per minute from the heart rate display in the field below and then click Submit to record your answer in the lab report. The smaller waves represent the contraction of the atria. During which portion of the cardiac muscle contraction is it possible to induce an extrasystole?
The amplitude of the ventricular systole did not change with the more frequent stimulation because You correctly answered: The ventricles must contract and relax fully with each beat to pump blood.
An extrasystole corresponds to You correctly answered: Review Sheet Results Explain why the larger waves seen on the oscilloscope represent the ventricular contraction.
Because ventricle contraction is strengther than atrial contraction. Explain why the amplitude of the wave did not change when you increased the frequency of the stimulation. How well did the results compare with your prediction? Amplitude did not change because of the cardiacs long refractory period, as predicted.
Why is it only possible to induce an extrasystole during relaxation? The extrasystole can not occur until relaxation and so we could not achieve wave summation tetanus. Explain why wave summation and tetanus are not possible in cardiac muscle tissue.
Cardiac cells have longer twitches than any other muscle cells. As I correctly predicted the cardiac muscle tissue did not show neither wave summation nor tetanus.Answers Abdominal Cavity Anatomy & Physiology Worksheet. Abdominal Cavity Anatomy & Physiology Worksheet 1.
