Chapter 2 [Body Organization] Terms Flashcards
The major body structural levels from smallest to largest are:
cells
tissues
organs
systems
body
is the fundamental unit of all living things.
cell
No matter the difference at some point during their life cycle, all cells have what
cytoplasm
nucleus
cell membrane
is the study of tissue.
Histology
cells group together and function together to perform a specific activity, they form
tissue
the four types of tissue in the body
muscular tissue
epithelial tissue
connective tissue
nervous tissue
Muscular tissue produces movement in the body through contraction, or shortening in length, and is composed of individual muscle cells called
muscle fibers
three basic types of muscles:
skeletal muscle
smooth muscle
cardiac muscle.
form the covering for and lining of body structures
absorb and secrete substances
excrete wastes
epithelium
provides structural support for the whole body.
bone
the shock absorber in joints.
cartilage
tightly connect skeletal muscles to bones.
tendons
provides protective padding around body structures
Adipose
what is connective tissue
adipose
bone
cartilage
tendons
Nervous tissue is made up of cells called
neurons
allowing for the conduction of electrical impulses to send information between
the brain and the rest of the body.
nerves
nervous tissue has
brain
nerves
neurons
spinal cord
different types of tissue that work as a unit to perform special functions
organs
several organs working in a coordinated manner to perform a complex function comprise what?
a system
forms protective two way barrier aids in temperature regulation
Integumentary System
Skeleton supports and protects body
forms blood cells, and stores mineral
muscles produce movement
Musculoskeletal System (MS)
Pumps blood throughout entire body to
transport nutrients, oxygen, and wastes
Cardiovascular System (CV)
Transports oxygen protects against
pathogens, and controls bleeding
blood [Hematic System]
Protects body from disease and
invasion from pathogens

Obtains oxygen from the environment
and removes carbon dioxide from
the body

Respiratory System
ingests, digest, and absorbs nutrients for the body
Digestive or Gastrointestinal (G)
System
filters waste products out of blood and removes them from body
Urinary System
Produces eggs for reproduction
provides place for growing bad,
nourishes infant
Female Reproductive System
Produces sperm for reproduction
Male Reproductive System
Regulates metabolic activities of
the body
Endocrine System
Receives sensory information and
coordinates body’s response
Nervous System
sensory organ that converts light into electrical impulses allowing for vision
ophthalmology
Sensory organ with dual purpose
converts sound waves into electrical
impulses allowing for hearing, and
maintains body’s sense of balance
otorhinolaryngology (ENT)
these structures are in what system?
Oral cavity

otorhinolaryngology (ENT)
is used when describing the postions and relationships of structures in the human body.
anatomical position
a body in the anatomical position is what?
standing erect, gazing straight ahead, arms down at sides,
palms facing forward, fingers
extended,
legs together
toes pointing forward`
runs lengthwise from front to back and
divides the body, or any of its parts, into right and left portions. The right
and left sides do not have to be equal.
Sagittal plane
if the sagittal plane passes through the middle of the body, into two right and left halves it is called a
midsigittal or median plane
A cut along the sagittal plane yields a
Sagittal section
divides the body into front and back
portions; a vertical, lengthwise plane is running from side to side:
Frontal plane or coronal plane
a cut along the frontal plane yields what?
Frontal or coronal section
is a crosswise plane that
runs parallel to the ground. This imaginary cut would divide the body, or
its parts, into upper and lower portions.
transverse or horizontal plane
A cut along the transverse plane
yields a
transverse section
