Mar 10, 2015 · The heart is a mostly hollow, muscular organ composed of cardiac muscles and connective tissue that acts as a pump to distribute blood throughout the body’s tissues.
Feb 24, 2021 · Function and anatomy of the heart made easy using labeled diagrams of cardiac structures and blood flow through the atria, ventricles, valves, aorta, pulmonary arteries veins, superior inferior vena cava, and chambers.
Below is a list of all the human heart diagrams and pictures included in this post: Picture of a Labelled Human Heart (parts of the human heart); Picture of a Non-Labelled (Numbered) Human Heart; Blood flow within the heart during diastolic and systolic phases; Oblique view of the human heart; Heart diagram: The myocardium and coronary vessels;
- Heart anatomy. The heart has five surfaces: base (posterior), diaphragmatic (inferior), sternocostal (anterior), and left and right pulmonary surfaces. It also has several margins: right, left, superior, and inferior
- Heart valves. Heart valves separate atria from ventricles, and ventricles from great vessels. The valves incorporate two or three leaflets (cusps) around the atrioventricular orifices and the roots of great vessels.
- Blood flow through the heart. The blood flow through the heart is quite logical. It happens with the heart cycle, which consists of the periodical contraction and relaxation of the atrial and ventricular myocardium (heart muscle tissue).
- Coronary circulation. The heart must also be supplied with oxygenated blood. This is done by the two coronary arteries: left and right. Heart muscles work constantly (thank goodness!)
