The CCIM Institute, headquartered in Chicago and an affiliate of the National Association of REALTORSÂ®, awards the CCIM designation to individuals who complete a process based both on commercial and investment real estate theory and practice. Weâll review this process in a moment.
The myocardium is the middle muscular layer of the heart's walls and it functions by providing a scaffolding for the heart chambers, assisting in contraction and relaxation of the cardiac walls so that blood can pass between the chambers and electrostimulation conduction through its own tissues and into the epicardium.
The two chambers on the bottom are called the ventricles (say: VEN-trih-kulz). The heart has a left ventricle and a right ventricle. Their job is to squirt out the blood to the body and lungs. Running down the middle of the heart is a thick wall of muscle called the septum (say: SEP-tum). The septum's job is to separate the left side and the right side of the heart.
