What does the heart look like and how does it work?Heart health: The heart pumps oxygenated red blood cells and nutrient-rich blood and other compounds like platelets throughout your body to sustain the life of your organs.
This article is designed to help individuals learn the heart anatomy and circulatory system, and provide some insight into heart health. It is not designed to present the many problems that can occur with the heart. Can Atrial Fibrillation Go Away?What is atrial fibrillation?Atrial fibrillation is a condition in which the heart beats irregularly and rapidly. During atrial fibrillation, the heart’s two upper chambers (the atria) beat irregularly without coordination with the two lower chambers (the ventricles) of the heart. Atrial fibrillation is usually due to damage to the heart's electrical system from conditions such as longstanding uncontrolled high blood pressure and coronary artery disease (narrowing of the blood vessels, coronary arteries, that supply the heart). Atrial fibrillation is also the most common complication after heart surgery. The symptoms of atrial fibrillation include:

Normal heart anatomy and physiologyNormal heart anatomy and physiology need the atria and ventricles to work sequentially, contracting and relaxing to pump blood out of the heart and then to let the chambers refill. When blood leaves each chamber of the heart, it passes through a valve that is designed to prevent the backflow of blood. There are four heart valves within the heart:

The pattern described below is repeated over and over (heart rhythm), causing blood to flow continuously to the heart, lungs, and body to supply oxygen and nutrients to the body cells and to deliver waste products to organs that remove them from your body. In general, veins return blood carrying CO2 while arteries usually contain O2 enriched red blood cells. However, the blood flow through the heart is a little different. For example: The right side of the heart

The blood first enters the right atrium. The blood then flows through the tricuspid valve into the right ventricle. When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery. The pulmonary artery carries blood to the lungs where it “picks up” oxygen.
What are the 17 steps of blood flow through the heart?Blood flows through the heart in the following order: 1) body –> 2) inferior/superior vena cava –> 3) right atrium –> 4) tricuspid valve –> 5) right ventricle –> 6) pulmonary arteries –> 7) lungs –> 8) pulmonary veins –> 9) left atrium –> 10) mitral or bicuspid valve –> 11) left ventricle –> 12) aortic valve –> 13) ...
