EXS 216 Test 1 Questions With Answers
100% Solved
Positive Feedback System - ANSWER Enhances the original stimulus; activity is
accelerated. example: blood clotting and labor contractions
Negative Feedback System - ANSWER System decreases or shuts off the original
stimulus or reduces the intensity. example: body temperature, heart rate, blood pressure,
blood glucose levels, etc.
Complimentary of Structure and Function - ANSWER Function ALWAYS reflects structure
Serous Membrane - ANSWER covers walls of ventral body cavity and outer surfaces of
organs. (parietal and visceral serosa)
Histology - ANSWER study of tissues
Structural Hierarchy - ANSWER (smallest to largest) atom, molecules,cells, tissue level,
organ, organ system, organismal level
Homeostasis - ANSWER Dynamic Balance
Functional Characteristics for Maintaining Life - ANSWER -Maintenance of boundaries
, -Movement (contractility)
-Responsiveness (excitability and conductivity)
-Digestion
-Metabolism (anabolism and catabolism)
-Excretion
-Reproduction
-Growth
catabolism - ANSWER breaking down
anabolism - ANSWER building up
Factors Influencing Rate of Chemical Reactions - ANSWER -Temperature (increases
chemical reaction)
-Particle Size (smaller the particle faster the reaction)
-Concentration (high concentrated= more reaction)
-Catalysts (speeds up the reaction)
Ph - ANSWER indicates the relative contraction of hydrogen ions in various body fluids.
acid - ANSWER 0-7 with 0 being most acidic
