Thanks to dozens of collaborators across the University of HawaiĘ»i System, an online, zero-cost textbook for two popular anatomy and physiology courses—Physiology 141 and 142—will replace the textbook that was used by almost 4,700 students during the last academic year for an estimated total savings of more than $433,000. The various textbooks currently used for these courses range in cost from $160 to $210. The new textbook is anticipated to be ready for fall 2023.
