The QS (Human Anatomy) and QT (Physiology) schedules were the major area of focus for the 2014 edition.

Two (2) QT schedule outline headers were changed:

• QT 180-245 Physiology. Hygiene was changed to QT 180-245 Hygiene.
• QT 250-275 Leisure Activities. Sports Medicine was changed to QT 250-275 Leisure Activities. Sports. Sports Medicine.

Some QS and QT class number captions and notes were revised to better reflect the scope of the number. For example:

The note was changed from Classify material on comparative physiology limited to animals in QP to Includes works on comparative physiology between humans and animals. Classify material on human physiology only in QT 104. Classify animal physiology in QP, QL, or SF.
• At QT 34, the caption was changed from Biophysics to Biophysical phenomena.
• At QT 36, the caption was changed from Biomedical engineering to Bioengineering. Biomedical engineering (General).
• At QT 36.5, the caption was changed from Nanotechnology to Microtechnology. Nanotechnology.
