Where is the heart located in the human body?

Step-by-step solution

Heart, the mesodermally derived organ , is situated in the thoracic cavity, in between the two lungs, slightly tilted to the left . It has the size of a clenched fist. It is protected by a double walled membranous bag, pericardium, enclosing the pericardial fluid. Our heart has four chambers, two relatively small upper chambers called atria and two larger lower chambers called ventricles.
