Circulation of blood. the heart is a roughly cone shaped hollow muscular organ. it is about 10 cm long and is about the size of the owner‟s fist. it weighs about 225 g in women and is heavier in men (about 310 g). the heart lies in the thoracic cavity in the mediastinum (the space between the lungs). System of veins is often called a low pressure system due to its function as a blood reservoir. apart from its blood reservoir function, blood flows back to the heart through veins.
