T he upper extremity is interesting from a functionalanatomy perspective because of the interplay amongthe various joints and segments necessary for smooth, effi-cient movement. Movements of the hand are made moreeffective through proper hand positioning by the elbow,shoulder joint, and shoulder girdle. he upper extremity is interesting from a functionalanatomy perspective because of the interplay amongthe various joints and segments necessary for smooth, effi-cient movement.

Artificial Organs. There is a critical shortage of donor organs of all types. Artificial organs that perform the function of natural organs can help alleviate this problem as well as sustain patients with organ failure as they await donor organs.In some cases, artificial organs can eliminate the need for transplantation altogether.here is a critical shortage of donor organs of all types. Artificial organs that perform the function of natural organs can help alleviate this problem as well as sustain patients with organ failure as they await donor organs.
Key points. 1  Humansâand other complex multicellular organismsâhave systems of organs that work together, carrying out processes that keep us alive. 2  The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.
