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 endocardium is the most inner layer of the heart. It forms the inner layer of all four heart chambers and is directly connected to all the inner cardiac appendages, such as the bicuspid valve, the tricuspid valve, the pulmonary valve, the aortic valve, the chordae tendineae and the papillary muscles.
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.
