Body parts are the various components that make up the human body. They can be categorized into two main groups: the upper body, which includes the head, arms, and torso, and the lower body, which consists of the legs and feet. Each part has specific functions, such as movement, sensation, and protection of vital organs. Different body parts work together to maintain overall health and functionality. For example, the heart pumps blood throughout the body, while the lungs facilitate breathing. Understanding body parts helps us appreciate how our bodies function and the importance of taking care of them.
