2. Anatomy of the human heart - Wikipedia

   en.wikipedia.org/wiki/Anatomy_of_the_human_heart

   The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...

4. Heart - Wikipedia

   en.wikipedia.org/wiki/Heart

   The heart is a muscular organ found in most animals.This organ pumps blood through the blood vessels. [1] Heart and blood vessels together make the circulatory system. [2] The pumped blood carries oxygen and nutrients to the tissue, while carrying metabolic waste such as carbon dioxide to the lungs. [3]

5. Atrium (heart) - Wikipedia

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

   Humans have a four-chambered heart consisting of the right and left atrium, and the right and left ventricle. The atria are the two upper chambers which pump blood to the two lower ventricles. The right atrium and ventricle are often referred to together as the right heart, and the left atrium and ventricle as the left heart.

6. Cardiac cycle - Wikipedia

   en.wikipedia.org/wiki/Cardiac_cycle

   The heart is a four-chambered organ consisting of right and left halves, called the right heart and the left heart. The upper two chambers, the left and right atria, are entry points into the heart for blood-flow returning from the circulatory system, while the two lower chambers, the left and right ventricles, perform the contractions that ...

8. 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.

9. Cardiac physiology - Wikipedia

   en.wikipedia.org/wiki/Cardiac_physiology

   Cardiac physiology or heart function is the study of healthy, unimpaired function of the heart: involving blood flow; myocardium structure; the electrical conduction system of the heart; the cardiac cycle and cardiac output and how these interact and depend on one another.
