LEVELS OF ORGANIZATION IN THE BODY Flashcards
Atoms are the simplest level of organization which
form molecules. Then, molecules aggregate to cells. Cells will
form tissues and when tissues combine with other tissues, they
form organs. Organs that work in groups are called the organ
system. Organisms will form when all organ systems work
together. (TRUE OR FALSE)
True
Atoms combine to form cells. (TRUE OR FALSE)
False (Correct Answer: Atoms combine to form molecules.)
The structural and functional characteristics of all
organisms are determined by their ____________.
chemical
makeup
Atoms such as hydrogen and carbon interact and
combine into molecules. This is important because a
molecule’s structure determines its function. (TRUE OR FALSE)
True
Cells are the basic structural and functional units
of all living organisms. It contains small structures
inside called ________.
organelles
___________ carry particular functions (digestion,
movement) for the cell.
Organelles
It is a group of similar cells and materials surrounding
them.
Tissue level
The characteristics of cells and the surrounding
materials determine the function of tissues. (TRUE OR FALSE)
True
What are the four basic tissue types?
epithelial,
connective, muscle, and nervous.
It is composed of two or more tissue types that
perform one or more common functions.
Organ level
Example of organ levels are urinary bladder, heart, stomach, and lungs. (TRUE OR FALSE)
True
It is a group of organs that work together to perform a
common function or set of functions viewed as a
unit.
Organ System level
It is an any living thing considered as a whole - whether
composed of one cell (bacterium) or trillions of cells
(humans).
Organism level
It is a network of organ systems
that are mutually dependent on one another.
Human organism
Integumentary system consists of kidneys, ureter, urinary
bladder, and urethra. (TRUE OR FALSE)
False (Correct Answer: Urinary system consists of kidneys, ureter, urinary
bladder, and urethra)
