The torso is the central part of the human body, excluding the head, arms, and legs. It contains vital organs such as the heart, lungs, and stomach, which are protected by the rib cage. The torso plays a crucial role in supporting the upper body and facilitating movement. In addition to humans, many animals also have a torso, which serves a similar function in housing essential organs. The torso is often studied in fields like anatomy and biology to understand body structure and function. It is also a key focus in art and sculpture, where the human form is often represented.
