Chapter 1 Homeostasis Flashcards
Define: Anatomy
The science of body structures and the relationships of them
Define: Physiology
the science of body functions
What are the 6 levels of structural organization?
Chemical, Cellular, Tissue, Organ, Organ system, Organism
branches of Anatomy & Physiology
embryology, developmental biology, cell biology, histology, endocrinology, immunology,
anatomy: gross, systemic, regional, surface, imaging, pathological
Physiology: cardiovascular, respiratory, neurophysiology, renal, exercise, pathophysiology
11 Body Systems
Integumentary, skeletal, muscular, nervous, cardiovascular, endocrine, lymphatic and immunity, respiratory, digestive, urinary, reproductive
Define: inspection
a noninvasive diagnostic technique to search for any deviations from normal on the visual level of the body
Define: palpation
feeling the body for any abnormalities
Define: auscultation
listening to the body for abnormalities
Define: percussion
tapping the body surface and listening for hollow or solid sounds
6 Basic life processes
Metabolism, responsiveness, movement, growth, differentiation, reproduction
Metabolism
the sum of all chemical processes in the body: catabolism–the breakdown of complex chemicals into simpler ones & anabolism–the building up of complex chemical substances
Differentiation
example: stem cells
Define: homeostasis
the condition of equilibrium in the body’s internal environment due to its interacting regulatory systems
Define: intracellular fluid, extracellular fluid, interstitial fluid
ICF–fluid within cells
ECF–fluid outside body cells, eg. blood plasma or lymph
interstitial fluid–the ECF between tissue cells
Feedback system
stimulus–controlled condition–receptor–control center (BRAIN)–effector–response–effects the controlled condition
