Final answer:
The term that describes a position away from the head or toward the lower part of the body is 'inferior' or 'caudal'.
Step-by-step explanation:
Away from the head end or toward the lower part of a structure of the body is described by the term inferior or caudal. This anatomical directional term indicates a position below or lower than another part of the body, nearer to the tail end in humans, which is the coccyx or lowest part of the spinal column. As an example, the pelvis is inferior to the abdomen. Understanding these directional terms, such as inferior, lateral (toward the side of the body), and medial (toward the middle of the body), is crucial in anatomy to describe the locations of body structures accurately.
