A significant pharmaceutical firm is investigating a novel medication that alters blood flow in sick tissue. The experiment includes a healthy 30-year-old man, and patterns of typical blood flow across various tissues are investigated. The illustration below demonstrates one of the patterns: The blood flow curve was most likely obtained from tissue of which of the following?

Eductional Objective: The surrounding muscle constricts the coronary arteries feeding the left ventricle during ventricular systole. As a result, diastole is when the bulk of left ventricular blood flow occurs. The subendocardial area of the left ventricle is particularly vulnerable to ischemia and infarction because it experiences the highest systolic drop in coronary blood flow.
