Anatomy and Physiology Chapter 1:
Principle of Complementarity of
Structure and Function: Questions
With Correct Answers 2026
Principle of Complementarity of Structure and function: - CORRECT ANSWER--For example
bones can support and protect body organs because they contain hard mineral deposits.
Chemical Level: - CORRECT ANSWER--At this level atoms, tiny building blocks of matter,
combine to form molecules such as water and proteins.
-Molecules in turn, associate in specific ways to form organelles that are the basic components
of living things.
Cellular Level: - CORRECT ANSWER--All cells share some common functions, but individual cells
vary widely in size and shape, reflecting their unique functions in the body.
-The simplest living creatures are single cells but in complex organisms such as human beings,
the hierarchy continues on to the tissue level.
Tissue Level: - CORRECT ANSWER--Tissues are groups of similar cells that have a common
function. The four basic types in the human body are epithelial tissue, connective tissue, and
nervous tissue.
Epithelial Tissue: - CORRECT ANSWER--Covers the body's surface and lines it's cavities.
Muscle Tissue: - CORRECT ANSWER--Provides movement.
Connective Tissue: - CORRECT ANSWER--Supports and protects body organs.
, Nervous Tissue: - CORRECT ANSWER--Provides a means of rapid internal communication by
transmitting electrical impulses.
Organ: - CORRECT ANSWER--Is a discrete structure composed of at least two tissue types (four
is common) that performs a specific function for the body.
Organ Level: - CORRECT ANSWER--Extremely complex functions become possible- the stomach
for example its lining is an epithelium that produces digestive juices.
Organ System Level: - CORRECT ANSWER--Organs that work together to accomplish a common
purpose make up an organ system.
-For example the heart and blood vessels of the cardiovascular system, circulate blood
continuously to carry oxygen and nutrients to all body cells.
Organism: - CORRECT ANSWER-The highest level of organization is the organism, the living
human being.
Organismal Level: - CORRECT ANSWER--Represents the sum total of all structural levels working
together to keep us alive.
Receptor (Sensor): - CORRECT ANSWER-Monitors environment
Responds to stimuli (things that cause changes in controlled variables)
Control Center: - CORRECT ANSWER--Determines set point at which variable is maintained,
receives input from receptor, determines appropriate response.
Effector: - CORRECT ANSWER--Receives output from the control center, provides the means to
respond response either reduces stimulas (Negative feedback) or enhances stimulas (Positive
feedback)
