There is generally no significant difference in the location of the heart between men and women, with most of the heart on the left side of the midline and a few on the right side, behind the body of the sternum and the cartilages of the 2nd to 6th ribs.
The form of the heart is an inverted, slightly flattened cone, surrounded by the pericardium, which is a hollow, fibrous organ. It is obliquely located in the middle mediastinum of the thoracic cavity, with about 2/3 of the heart located to the left of the median line and the remaining 1/3 to the right of the median line.
The heart is located posterior to the body of the sternum and the cartilages of the 2nd to 6th ribs; the posterior aspect of the heart lies flat against the 5th to 8th thoracic vertebrae; the pleural cavity and the lungs are on either side of the heart, adjacent to it.
It should be noted that in a small number of people, the heart can sometimes be inverted and become right-sided, and is often accompanied by inversion of the internal organs in the abdominal cavity.
If there is any discomfort, it is recommended to seek medical attention and treatment.
