  2. Heart - Wikipedia

    en.wikipedia.org/wiki/Heart

    The heart is a muscular organ found in humans and other animals.This organ pumps blood through the blood vessels. [1] Heart and blood vessels together make the circulatory system. [2]

  3. Heart development - Wikipedia

    en.wikipedia.org/wiki/Heart_development

    The heart derives from embryonic mesodermal germ layer cells that differentiate after gastrulation into mesothelium, endothelium, and myocardium.Heart induction occurs in the anterior mesoderm during gastrulation through interactions with adjacent endoderm (both extra-embryonic and definitive) mediated primarily by endogenous inhibitors of WNT signaling such as DKK1.

  4. Atrium (heart) - Wikipedia

    en.wikipedia.org/wiki/Atrium_(heart)

    The atrium (Latin: ātrium, lit. 'entry hall'; pl.: atria) is one of the two upper chambers in the heart that receives blood from the circulatory system.The blood in the atria is pumped into the heart ventricles through the atrioventricular mitral and tricuspid heart valves.

  5. Cardiac skeleton - Wikipedia

    en.wikipedia.org/wiki/Cardiac_skeleton

    In cardiology, the cardiac skeleton, also known as the fibrous skeleton of the heart, is a high-density homogeneous structure of connective tissue that forms and anchors the valves of the heart, and influences the forces exerted by and through them.

  6. Endocardium - Wikipedia

    en.wikipedia.org/wiki/Endocardium

    Illustration depicting the layers of the heart wall including the innermost endocardium. The endocardium (pl.: endocardia) is the innermost layer of tissue that lines the chambers of the heart.

  7. Ventricle (heart) - Wikipedia

    en.wikipedia.org/wiki/Ventricle_(heart)

    A ventricle is one of two large chambers located toward the bottom of the heart that collect and expel blood towards the peripheral beds within the body and lungs. The blood pumped by a ventricle is supplied by an atrium, an adjacent chamber in the upper heart that is smaller than a ventricle.

  8. Crux cordis - Wikipedia

    en.wikipedia.org/wiki/Crux_cordis

    Back side and base of the heart. The coronary sinus (labeled) runs in the coronary sulcus; the middle cardiac vein (labeled) runs in the posterior interventricular sulcus. . The two sulci meet in the crux cord

  9. Cardiac conduction system - Wikipedia

    en.wikipedia.org/wiki/Cardiac_conduction_system

    The cardiac conduction system (CCS, also called the electrical conduction system of the heart) [1] transmits the signals generated by the sinoatrial node – the heart's pacemaker, to cause the heart muscle to contract, and pump blood through the body's circulatory system.
