Answer:
Our legs are an example of levers in the human body. Levers are a bar free to pivot or move about a fixed point when an input force is applied. They help us to lift things more easily by pivoting about a fulcrum.
Our teeth are an example of a wedge found in our body. Wedges work by putting a narrow end into something we want to come apart, and applying force to the wider end. When we eat, we put our bottom teeth into the middle of the food and break it apart with our top teeth. A wedge is also known as two inclined planes that work together; each row is one inclined plane.
