Systemic: one system at a time. Regional: all systems in one specific region. Embryology: conception to 8 weeks gestation. Pathologists use gross inspection, histology, cytology, and examinations to discover source of the disease. Clinical connection: autopsy is postmortem exam performed by pathologist, done to determine cause of death, identify diseases, determine extent of injuries, and identify heredity conditions. Levels of organization: chemical, cellular, tissues (epithelium, muscle, connective, nerves), organs (made from two or more types of tissues), organ system (eleven in the body), and organism, life processes.

Ecf between cells and fluids: blood plasma. Ecf within lymphatic vessels: cerebrospinal fluid. Ecf in brain and spinal cord: synovial. Ecf in eyes: cellular function depends as interstitial fluid. Composition changes as substances move between plasma and interstitial fluid.
