Human Heart Anatomy Diagram - Key Valves Explained #1202505 (License: Personal Use)

This medical illustration presents a sagittal view of the human heart with precise labeling of the four primary valves: the tricuspid valve (right atrium to right ventricle), pulmonary valve (right ventricle to pulmonary artery), mitral valve (left atrium to left ventricle), and aortic valve (left ventricle to aorta). The diagram uses color-coding-blue for deoxygenated pathways and red for oxygenated-to clarify blood flow direction and chamber function.

Used in educational contexts such as biology textbooks, medical training modules, health websites, and patient education materials to explain cardiac anatomy and valve function; matches user intent for learning or teaching cardiovascular physiology.
