Question

the heart skeleton is fibrous connective tissue that acts as an electrical barrier between the atria and ventricles. if this structure was not functional, which of the following conditions might occur? multiple choice increase in pericardial fluid in the pericardial space occlusion of the coronary arteries spread of ectopic stimuli from the atria to the ventricles blood flow from the right atrium to the left atrium

Explanation:

The fibrous connective - tissue between atria and ventricles acts as an electrical barrier. If it fails, abnormal electrical signals (ectopic stimuli) from the atria can spread to the ventricles. An increase in pericardial fluid is related to pericardial issues, occlusion of coronary arteries is due to blockages in those vessels, and blood flow from right atrium to left atrium is related to septal defects, not failure of this electrical - barrier tissue.

Answer:

C. Spread of ectopic stimuli from the atria to the ventricles
