Which directional term is used to describe parts of the torso that are further away from the head?

A part of the body that is further away from the head is inferior. The term inferior is typically used for structures in the torso, such as the inferior vena cava. In the upper and lower extremities, parts that are further from the point of origin are generally referred to as “distal”. However sometimes “inferior” is used to mean “toward the feet”. Another word for inferior is “caudal” which means “towards the tail”. “Caudal” is more commonly used by biologists who study other animals in addition to humans. But you may occasionally see this in anatomy books.
