The heart is a vital organ in the human body responsible for pumping blood throughout the circulatory system. It is divided into four chambers: the right atrium, right ventricle, left atrium, and left ventricle. The flow of blood through the heart is controlled by a series of valves, including the tricuspid valve, pulmonary valve, mitral valve, and aortic valve.
The deoxygenated blood coming from the body enters the right atrium, then flows into the right ventricle through the tricuspid valve. From there, it is pumped to the lungs for oxygenation through the pulmonary valve. Once oxygenated, the blood returns to the heart and enters the left atrium, then flows into the left ventricle through the mitral valve. Finally, the oxygenated blood is pumped out to the body through the aortic valve.

Cardiac Cycle
The cardiac cycle is the sequence of events that occur during one heartbeat. It consists of two phases: diastole and systole. During diastole, the heart relaxes, allowing the chambers to fill with blood. This is followed by systole, where the heart contracts to pump blood out to the body. The cardiac cycle is controlled by electrical impulses generated by the heart’s natural pacemaker, the sinoatrial (SA) node.
Understanding the flow chart of the heart is essential for comprehending how blood circulates in the body. By visualizing the pathway of blood through the heart and the cardiac cycle, we can appreciate the complexity and efficiency of this life-sustaining process. Proper functioning of the heart is crucial for maintaining overall health and well-being.
Conclusion
In conclusion, the flow chart of the heart provides a clear illustration of how blood circulates through this vital organ. By understanding the anatomy of the heart, the role of valves, and the cardiac cycle, we gain insight into the intricate process of circulation. Maintaining a healthy heart through regular exercise, a balanced diet, and lifestyle choices is essential for overall well-being. Remember, a healthy heart leads to a healthier life.
