Intracellular fluid 

with in the cells

Interstital fluid

surrounding cells with in the vessels

Intravascular fluid

in vessels and lymph

Crystalloid fluid

hypotonic/isotonic composed of water rich with electrolytes, has small solutes that can cross the vascular wall (NACI, lactated, ringers)

Element

single, pure substance consisting of only one atom

Molecule 

formed by atoms joined by chemical bonds

Compound

two or more different elements joined by chemical bonds

ATP

Health 

Proper functioning of each of the body’s systems, organs, tissues, and cells

Disease

structures/functions become abnormal

Homeostasis

maintenance of a dynamic equilibrium in the body

Microscopic Anatomy

deals with structures that are very small, cells and tissues.

Macroscopic Anatomy 

deals with large body parts, organs, bones, and muscles (gross)

Physiology

functions of the body and its parts

Anatomy

form and structure of the body and its parts

Organs 

group of tissues that work together for a common purpose

Body systems

group of organs, tissues, and cells that work together to perform essential functions.
