Heart, Anatomy

Model Of The Superficial Anatomy Of The Heart Of An Adult Human Body Anterior View. The Heart Contains Four Cavities: Two Atriums In Its Upper Part, And Two Ventricles In Its Lower Part. The Atriums Are Covered Anteriorly By The Auricles In Beige, Which Increase Their Blood Capacity. The Ventricles In Light Orange Have Superficial Grooves The Sulci, In Amber Yellow, That Contains Fat And The Coronary Circulation, Feeding The Heart Muscle. At The Boundary Between The Right Atrium And Ventricle, The Coronary Sulcus Receives The Right Coronary Artery In Red. In The Anterior Interventricular Sulcus, Which Marks The Boundary Between Both Ventricles, Lie The Great Cardiac Vein In Royal Blue And The Anterior Interventricular Branch Of Left Coronary Artery In Red. The Superior Vena Cava In Royal Blue, In The Background Brings The Deoxygenated Blood To The Heart Right Atrium, Which Propels It To The Lungs Via The Pulmonary Trunk, Dividing In Right And Left Pulmonary Arteries In Royal Blue, In The Foreground. The Oxygenated Blood Is Next Sent Back From The Lungs To The Heart Left Atrium Through The Left Pulmonary Veins In Red. The Heart Expels Then The Blood To The Whole Body Via The Arch Of Aorta In Red, Which Branches Into The Brachiocephalic Trunk, The Left Common Carotid Artery And The Left Subclavian Artery. The Upper Trachea Cartilaginous Rings In Light Blue And Esophagus In Reddish Brown Segments Are Visible Behind The Heart. (Photo By BSIP/UIG Via Getty Images)
