Distal
The more (or most) distant of two (or more) things. For example, the distal end of the femur (the thigh bone) is the end down by the knee. For another example, the distal bile duct is the far end of the cystic duct, the end away from the gallbladder. And for a last example, the distal lymph node in a chain of nodes is the most distant one. The opposite of "distal" is "proximal." Taking the same three examples, the proximal end of the femur is the end of the thigh bone up by the hip, the proximal bile duct is the end nearest the gallbladder), and the proximal lymph node is the nearest one of all nodes under consideration.
