14. Assume that a string is tied around the heart at the level shown in the
diagram by the red line Assume also that the string is tied loosely enough to
simulate human first-degree heart block. State the effect of this procedure
on the atria:ventricle contraction ratio AND explain the underlying physiology
related to the effect.

Expert Solution
Step 1
Introduction:
Human's and frog's circulatory system is similar, comprising one circuit that brings and takes back the blood to the lungs and pumping the blood to the body tissues. The difference is that there is only one ventricle in a frog's heart that pumps the blood into boh the circuit.
