Anatomy - correct answer - the science of body structures and the
relationships among them
Chemical level of structural organization - correct answer - atoms (smallest
units of matter) and molecules (two or more atoms joined together)
Can be compared to letters
Cellular level of structural organization - correct answer - molecules
combine to form cells (the basic structural and functional units of an
organism that are composed of chemicals
Compared to words
Tissue level of structural organization - correct answer - groups of cells and
the materials surrounding them that work together to perform a particular
function
, Page |2
Can be compared to sentences
Organ level of structural development - correct answer - different tissues
are joined together to form organs (structures with specific functions and
recognizable shapes)
Compared to paragraphs
System level of structural organization - correct answer - consists of related
organs with a common function
Can be compared to chapters
Organism level of structural organization - correct answer - any living
individual
Can be compared to the book
Integumentary system (components and function) - correct answer - skin
and associated structures, such as hair, fingernails and toenails, sweat
glands, and oil glands.
, Page |3
Protects body; helps regulate body temperature; eliminates some wastes;
helps make vitamin d; detects sensations such as touch, pain, warmth, and
cold; stores fat and provides insulation.
Skeletal system (components and function) - correct answer - bones and
joints of the body and their associated cartilages.
Supports and protects body; provides surface area for muscle attachments;
bone aids body movements; houses cells that produce blood cells; stores
minerals and lipids (fats).
Muscular system (components and function)` - correct answer - specifically,
skeletal muscle tissue—muscle usually attached to bones (other muscle
tissues include smooth and cardiac).
Participates in body movements, such as walking; maintains posture;
produces heat.
Nervous system (components and function - correct answer - brain, spinal
cord, brain nerves, and special sense organs, such as eyes and ears.
Generates action potentials (nerve impulses) to regulate body activities;
detects changes in body's internal and external environments, cord
interprets changes, and responds by causing muscular contractions or
glandular secretions.
, Page |4
Endocrine system (components and function) - correct answer - hormone-
producing glands (pineal gland, hypothalamus, pituitary gland, thymus,
thyroid gland, parathyroid glands, adrenal glands, pancreas, ovaries, and
testes) and hormone-producing cells in several other organs.
Regulates body activities by releasing hormones (chemical messengers
transported in blood from endocrine gland or tissue to target organ).
Cardiovascular system (components and function) - correct answer - blood,
heart, and blood vessels
Heart pumps blood through blood vessels; blood carries oxygen and
nutrients to cells and carbon dioxide and wastes away from cells and helps
regulate acid-base balance, temperature, and water content of body fluids;
blood components help defend against disease and repair damaged blood
vessels.
Lymphatic and immunity system (components and function) - correct
answer - lymphatic fluid and vessels; spleen, thymus, lymph nodes, and
tonsils; cells that carry out immune responses (b cells, t cells, and others).
Returns proteins and fluid to blood; carries lipids from gastrointestinal tract
to blood; contains sites of maturation and proliferation of b cells and t cells
that protect against disease-causing microbes.
