Chapter 2 Flashcards
Anatomic Reference Systems
terms used to describe the location of body planes, directions, and cavities
structures of the body
the cells, tissues, and glands that form the body systems that work together to enable the body to function properly
Genetics
the genetic components that transfer characteristics from parents to their child
Tissues
