Is the heart on the left or right side?
Generally, the heart is located on the left side. The detailed explanation is as follows:
The heart is primarily composed of cardiac muscle tissue and has the appearance of red muscle. Its surface is covered by a thin membrane called the pericardium, which protects and stabilizes the heart. The heart is roughly cone-shaped or oval-conical, slightly tilted, with the left side slightly larger than the right. It consists of four chambers: the left atrium, right atrium, left ventricle, and right ventricle. In a normal individual, a small portion of the heart lies on the right side, while the majority is positioned on the left, along with the aorta and major blood vessels. Specifically, the heart is located within the thoracic cavity above the diaphragm, with approximately two-thirds of it lying to the left of the mid-sternal line. The left ventricle inside the heart is stronger than the right ventricle, enabling more efficient and adequate blood circulation throughout the body, which explains why most of the heart is situated on the left side. The heart performs vital functions including pumping blood, maintaining the circulatory system, regulating blood pressure, facilitating oxygen and carbon dioxide exchange, immune regulation, and maintaining acid-base balance.
If any abnormalities occur in the heart, it is recommended to seek medical attention promptly to prevent worsening of the condition.
