BIOL 235 Exam Study Questions with Correct
Detailed Answers 2025 Graded A+
define the terms anatomy and physiology -Correct Answers ✔-provide the basic
understanding of the body parts and functions
anatomy -Correct Answers ✔-is the science of the body structures and the
relationships around them
dissection -Correct Answers ✔-the careful cutting of the body structures to study
their relationships
physiology -Correct Answers ✔-is the study of body functions-how the body parts
work
different levels of structural organization -Correct Answers ✔-chemical, cellular,
tissue, organ, system, and organism
chemical level -Correct Answers ✔-atoms - smallest units of matter that participate
in chemical reactions
molecules - two or more atoms joined together; carbon, hydrogen, oxygen,
nitrogen, phosphorous, calcium, and sulphur are essential for maintaining life
cellular level -Correct Answers ✔-cell - the basic structural and functional units of
an organism that are composed of chemicals - smallest living units of the body,
muscle cells, nerve cells, epithelial cells
tissue level -Correct Answers ✔-tissues - are groups of cells and the materials
surrounding them that work together to perform a specific function
(four types)
BIOL 235
,BIOL 235
epithelial - covers the bodies surfaces, lines hollow organs & cavities
connective tissue - connects, protects, and supports the body organs while
distributing blood vessels to other tissues
muscular - contracts to make the body parts move and generates heat
nervous - which carries information from one part of the body to another through
nerve impulses
organ level -Correct Answers ✔-organs - are structures that are composed of two
or more different types of tissues; they specific functions and usually recognizable
shapes, eg. heart, skin, stomach, liver, lungs, and brain
system -Correct Answers ✔-system - consists of related organs with common
functions , an example of a system (organ-system level) is the digestive system,
which breaks down and absorbs food
organismal -Correct Answers ✔-all the body parts functioning together constitutes
a living organism
identify 11 systems of the human body -Correct Answers ✔-integumentary,
skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory,
digestive, urinary, reproductive
integumentary system -Correct Answers ✔-components-skin and associated
structures, such as hair, fingernails, toenails, sweat glands, and oil glands
function-protects they body; helps regulate temperature, manage waste, produce
vitamin D, detects sensations such as touch, pain, warmth, cold; stores fat and
provides insulation
skeletal system -Correct Answers ✔-components-bones & joints of the body and
their associated cartilages
BIOL 235
,BIOL 235
function-supports and protects the body, provides surface area for muscle
attachments, aids body movements, houses cell that produce blood cells, and stores
minerals and lipids
muscular system -Correct Answers ✔-components-specifically skeletal muscle
tissue, muscle usually attached to bones, other includes smooth cardiac muscle
tissue
function-participates in movements, such as walking; maintains posture; produces
heat
nervous system -Correct Answers ✔-components-brain, spinal cord, nerves, and
special sense organs, such as eyes and ears
function-generates action potential (nerve impulses) to regulate body activities,
changes in internal/external environment, interprets/responds to changes causing
muscular contractions or glandular secretions
endocrine system -Correct Answers ✔-components-hormone producing glands;
pineal gland, hypothalamus pituitary gland, thymus, thyroid gland, parathyroid
glands, adrenal glands, pancreas, ovaries, and testes, as well as hormone producing
cells in other organs
function-regulates body activities by releasing hormones (chemical messengers
transported into the blood from endocrine gland or tissue to target organ)
cardiovascular system -Correct Answers ✔-components-blood, heart, and blood
vessels
function-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
BIOL 235
, BIOL 235
lymphatic system -Correct Answers ✔-components-lymphatic fluid and vessels;
spleen, thymus, lymph nodes, and tonsils; cells that carry out immune responses (B
cells, T cells, and others)
functions-returns proteins and fluids to blood; carries lipids from gastrointestinal
track to the blood; contains sites of maturation and proliferation of B cells and T
cells that protect against disease-causing microbes
respiratory system -Correct Answers ✔-components-lungs and air passageways
such as the pharynx (throat), larynx (voice box), trachea (windpipe), and bronchial
tubes leading into and out of lungs
functions-transfers oxygen from inhaled air to blood and carbon dioxide from
blood to exhaled air; helps regulate acid-base balance of body fluids; air flowing
out of lungs vocal cords produces sounds
digestive system -Correct Answers ✔-components-organs of gastrointestinal tract,
a long tube that includes the mouth pharynx (throat), esophagus (food tube),
stomach, small and large intestines, and anus; also includes accessory organs that
assist in digestive processes, such as salivary glands liver, gallbladder, and
pancreas
functions-achieves physical and chemical breakdown of food; absorbs nutrients;
eliminates solid waste
urinary system -Correct Answers ✔-urinary-kidneys, ureters, urinary bladder, and
urethra
functions-produces, stores, and eliminates urine; eliminates wastes and regulates
volume and chemical composition of blood; helps maintain the acid-base balance
of body fluids; maintains body's mineral balance; helps regulate production of red
blood cells
