(Chapter 1 And Chapter 2) Questions
with Quality Answers 2026 Update.
Anatomy - Answer Study of structure and relationships among structures.
Physiology - Answer Study of how body structure’s function
Levels of Structural Organization - Answer -Chemical
-Cellular
-Tissues
-Organs
-Systems
-Organism
Characteristics of all living things - Answer -Metabolism
-Responsiveness
-Movement
-Growth
-Differentiation
-Reproduction
Metabolism - Answer Sum of all chemical processes that occur in the body
Responsiveness - Answer Ability to detect and respond to changes in external or internal
enviroment
Movement - Answer Motion of whole body, individual organs, single cells, or organelles
inside of cell
Growth - Answer An increase in size and complexity, due to an increase in the number of
cells, size of cells, or both.
Differentiation - Answer Change in a cell from a non-specialized state to a specialized state
, Reproduction - Answer Refers either to formation of new cells for growth, repair or
replacement OR the production of a new individual
Homeostasis - Answer Condition in which the body's internal environment remains within
certain physiological limits
Extracellular Fluid (ECF) - Answer Fluid outside of body cells
Intracellular Fluid (ICF) - Answer Fluid within body cells
When is an organism said to be in homeostasis? - Answer Conditions in the internal
environment are maintained within physiological limits
Stress - Answer Any external or internal stimulus that creates an imbalance in the internal
environment
How does the nervous system regulate homeostasis? - Answer -Detects body changes
-Sends nerve impulses to counteract the stress
How does the endocrine system regulate homeostasis? - Answer Secreting hormones
Feedback System (loop) - Answer A cycle of events in which information about the status of a
condition is continually monitored and fed back (reported) to a central control region.
Stimulus - Answer Any stress that changes a controlled condition
Three basic components of a feedback system: - Answer -Control Center
-Receptor
-Effector
Control Center - Answer Determines the point at which a controlled condition should be
maintained
Receptor - Answer Monitors changes in the controlled condition and then send the
information, called the input, to the control center
