The heart’s apex, or inferior tip, is located directly to the left of the sternum, near the articulation of the fourth and fifth ribs with the costal cartilages. The major veins, the inferior and superior vena cava, and the major arteries, the aorta and pulmonary trunk, are all connected to the base of the heart. The heart's dorsal surface is close to the vertebral bodies, while its anterior surface is close to the sternum and costal cartilages.

The pericardium, or pericardial sac, separates the cardiac from the other mediastinal organs inside the mediastinum, and it resides in its own compartment termed the pericardial cavity. The human heart is positioned in the thoracic cavity, inside the mediastinum, which is the region between both lungs. Where is the Heart Located in the Human Body? Questions like where is the heart located in the human body is also answered in the article. The article discusses the anatomy and the physiology of the human heart, it also describes aspects like the structure of the heart and the function of the heart. Your heart's function is controlled by your brain and nerve system. The heart is made up of four main chambers that are driven by electrical impulses and are formed of muscle. The heart of animals with lungs like amphibians, reptiles, birds, and mammals has evolved from a single pump to a double pump that circulates blood. It's the human circulatory system's principal organ. The human heart is a fist-sized hollow muscular organ made up of specialized cell types that is responsible for pumping blood through the circulatory system. It is supported by the diaphragm, the muscular barrier that separates the chest and abdominal cavities. In humans, the heart is located beneath the breastbone, in between two lungs and somewhat to the left of the centre.
