Study Notes
Heart Surfaces
- Anterior (sternocostal) surface: Located forward, upward, and to the left; associated with the sternum and ribs.
- Diaphragmatic surface: Faces downward and slightly backward; primarily made up of the left ventricle and related to the diaphragm.
- Right pulmonary surface: Mostly composed of the right atrium.
- Left pulmonary surface: Predominantly formed by the left ventricle.
