BIO 277 UNIT 1 UNCG EXAM QUESTIONS WITH
COMPLETE ANSWERS
homeostasis - ANSWER the physical concept of physiology
Homeostasis - ANSWER refers to the body's dynamic maintenance of
optimal physical conditions,including plasma volume and osmolarity, blood gas composition,
blood pressure,pH, glucose levels, etc
A simple homeostasis loop - ANSWER consists of
controlled variable ->sensors-> integrating system->effectors
controlled - ANSWER All _________________ variables
are monitored by some type of receptor, which reports to an integrating center
(usually the central nervous system).
integrating center - ANSWER The _______________ _________________ processes
information and sends correcting signals (usually via nerves or hormones) to
different effector tissues that change their activity and hopefully bring the variable
back to within it's normal range.
, 60% - ANSWER Human bodies are mostly (about ___%) water. Our body's water is partitioned
within 3 distinct compartments: inside the cell
3 - ANSWER Our body's water is partitioned
within _____ distinct compartments:
Where our bodies water compartments are - ANSWER inside the cells (intracellular fluid or
cytosol), the space in between the cells (interstitial fluid), and the fluid (plasma) in the blood
vessels . Together the interstitial fluid and the plasma are referred to as
extracellular fluid, meaning the water outsid
interstitial fluid - ANSWER Together the _______________________ and the plasma are referred to
as extracellular fluid
extracellular fluid - ANSWER meaning the water outside of the cells
67% - ANSWER ______ of body water is inside of the cell (intracellular fluid)
proteins - ANSWER includesenzymes,transporters,receptors,hormones, and other signals, and
structural and contractile proteins
scaffolding - ANSWER proteins form the "__________" of cells
