Location of the Heart in the Human Body
Heart Location in the Thoracic Cavity
The heart is a muscular organ located in the thoracic cavity, specifically within the middle mediastinum. It is positioned between the lungs and in front of the esophagus, resting above the diaphragm and behind the sternum . The heart is encased in a protective sac known as the pericardium, which provides a frictionless environment for its movements.
Position Relative to Other Structures
The heart lies obliquely within the chest, with about two-thirds of its mass situated to the left of the midline of the body and one-third to the right . The base of the heart is directed dorsocranially to the right, while the apex points ventrocranially to the left. This positioning allows the heart to efficiently pump blood through the body’s circulatory system.
Mediastinal Compartments
The heart is located in the middle mediastinum, a central compartment of the thoracic cavity. The anterior mediastinum, the space between the heart and the sternum, contains no significant structures, making it a common surgical approach to the heart. The posterior mediastinum, located between the heart and the vertebral column, houses vital structures such as the trachea, esophagus, and major blood vessels.
Anatomical Landmarks
In terms of anatomical landmarks, the heart is situated under the lower third of the sternum. This positioning is consistent across different age groups, from infants to adults. The heart's location relative to the sternum is crucial for procedures like external cardiac massage during cardiopulmonary resuscitation (CPR).
Conclusion
Understanding the precise location of the heart within the thoracic cavity is essential for both clinical and surgical practices. The heart's position between the lungs, in front of the esophagus, and above the diaphragm, along with its encasement in the pericardium, allows it to function effectively as the central pump of the circulatory system. This anatomical knowledge is vital for accurate diagnosis, treatment, and emergency interventions.
