Anatomy and physiology 101 final exam ivy tech 2025 update comprehensive frequently
tested questions and verified answers with rationales| accurate answers|100% solved!!
What is the difference between anatomy and physiology - -anatomy- study of structure
physiology- study of function
--what are the levels of organization - -subatomic particle- protons, electrons, neutrons
atom
molecule
macromolecule
organelle
cell
tissue
organ
organ system
organism
--what are the characteristics of life? - -movement
responsiveness
respiration
absorption
secretion
digestion
assimilation- changing of absorbed substances into chemically different forms
circulation
reproduction
growth
--what are the requirements of life? - -water
food
heat
pressure
oxygen
--define homeostasis - -maintaining of a stable enviroment
--what is a homeostatic mechanism - -monitors aspects of internal environment and
corrects as needed
*negative feedback mechanism
--define matter - -anything that takes up space and has mass
--element - -composed of chemically identical atoms
--atom - -smallest particle of atom, basic unit of matter
--what are structure of an atom - -nucleus
protons
, neutron
electrons
--define nucleus, proton, electron, neutron - -nucleus- central part of atom
proton- positive charge
electron- negative charge
neutron- no electrical charge
--ionic bond - -formed when electrons are transferred from one atom to another
--what are covalent bonds - -when two molecules share electron
--hydrogen bond - -formed between water molecule, attraction between positive end of
polar molecule and negative end of another polar molecule
--define synthesis, decomposition, and exchange reactions - -Synthesis- A+B=AB
Decomposition- AB=A+B
exchange- AB+CD=AD+BC
--define reactant - -starting materials of reactions
--product - -ending material
--define catalyst - -a substance that speeds up a chemical reaction
--what is an acid - -dissociates with water
--base - -combines in water
--what happens to salts when dissolved in water and what is produced? - -The salt
molecules are "torn apart" by the water, and are reduced to sodium (Na+) and chlorine (Cl-)
ions.
--what is the pH scale? what ions are involved in the pH scale? - -pH scale- indicated the
concentration of hydrogen ions in a solution, H+ and OH-
--organic molecule - -contains Carbon and hydrogen and dissolves in water.
--inorganic molecule - -does not contain C and H and dissociates with water
--What is dehydration synthesis - -taking water out (producing water) to form a new
product. Uses energy
--hydrolysis - -separation of two macromolecules by adding water. Releases energy
--what are carbohydrates - -provide energy and cell structure
