Anatomy and Physiology Module 1-2 Flashcards
(40 cards)
Anatomy
studies structures of body parts and relationship to one another
Physiology
studies function of the body and how it works
Catabolism
metabolic pathways that breakdowns molecules into smaller units either oxidized to release energy or used for anabolic reactions
Anabolism
pathways that construct molecules from smaller units; requires energy also know as ENDERGONIC PROCESS
Homeostatis
ability to maintain relatively stable internal conditions
Homeostatic Imbalance
inability of the body to restore a functional and stable environment
Visceral
covers the organ
Parietal
lining the walls
Serous Fluid
lubricating fluid that separates the serosa
Colloid
solute particles are larger in solution and scatter light; do not settle out
Suspension
solute particles are very large, settle out and may scatter light
Organic Compounds
contain carbon and made by living things
Inorganic Compounds
lacks carbon except carbon except carbon dioxide and carbon monoxide
Polyatomic Ions
groups of atoms that bear an overall charge
Acids
also called proton donors. Substance that release hydrogen ions in detectable amounts
Bases
proton acceptors. Substance that take up hydrogen ion is detectable amount
pH
measures the relative concentration of hydrogen ions in various body fluids
Neutralization
when acids and bases mix, displacement reaction occur to form water and salt
Macromolecule
large complex of molecule with thousands of atoms
Cells
smallest unit of life, all organism are made out of
Nucleus
organelle that controls cellular activities
Cytoplasm
intracellular fluid packed with organelles
Plasma Membrane
selectively permeable barrier
Cellular Secretions
substances that aid in digestion (gastric fluid) or act as lubricants (saliva)
