Coronary Circulation

Overview

• Coronary: Derived from Latin 'coronarius' meaning crown.
  • Refers to the coronary blood vessels surrounding the heart like a crown.
• Circulation: Refers to the flow of blood.

Coronary Circulation

• Definition: Movement of blood through vessels supplying the myocardium (heart muscle).
• Myocardium: Heart muscle made up of cardiac muscle cells, known as cardiomyocytes.

Functionality

• Cardiac Muscle Cells (Cardiomyocytes):
  • Require a steady supply of oxygen and nutrients.
  • Need a mechanism to eliminate waste.
• Why Coronary Circulation?
  • Despite the heart pumping blood, myocardium is too thick for effective diffusion.
  • Coronary circulation provides an efficient way for the exchange of substances.
