Hierarchy of Structural Organization
Chemical- chemical, mechanical, or electrical events that occur within and between
cells
Cellular- fundamental compartments of all living things and the molecules/organelles
working together
Tissue- groups of cells working together to perform a common function
Organ- a group of tissues working together to perform specific functions.
Organ systems- group of organs working together
Organism- A human is an organism
How many organ systems are in the human body?
11
Would blood vessels be classified as organs?
Yes
What are the 11 organ systems
Integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic,
digestive , respiratory, urinary, male/female reproductive
Integumentary system
,skin, hair, sweat glands, nails
Fn: protect against environmental hazards, regulate body temperature, provide sensory
information
Skeletal system
bones, cartilage, associated ligaments, bone marrow
Fn: provides support and protection for other tissues, stores calcium and other minerals,
forms blood cells
Muscular system
skeletal muscles (>650) and associated tendons
Fn: provides movement, provides protection and support for other tissues, generates
heat that maintains body temperature.
Nervous System
brain, spinal cord, peripheral nerves, sense organs
Fn: direct immediate responses to stimuli
coordinate/moderate activity of other organ systems.
provides/interprets sensory information
Endocrine System
pituitary gland, pancreas, gonads, endocrine tissues in other systems, thyroid gland,
adrenal gland.
Fn: directs long-term changes in the activities of other organs
adjusts metabolic activity and energy use by the body
controls structural and functional changes during development
Cardiovascular system
,heart, blood, blood vessels
Fn: Distributes blood
cells, water and dissolved materials including nutrients, waste products, oxygen, and
carbon dioxide
Distributes heat and assists in control of body temperature
Lymphatic system
spleen, thymus, lymphatic vessels, lymph nodes, tonsils
Fn: defends against infection and disease
returns tissue fluids to the bloodstream
Respiratory system
nasal cavity, sinuses, larynx, trachea, bronchi, lungs, alveoli
Fn: delivers air to alveoli
provides oxygen to bloodstream
removes CO2 from bloodstream
produces sound for communication
Digestive system
teeth, tongue, pharynx, esophagus, stomach, small intestine, large intestine, liver,
gallbladder, pancreas
Fn: processes and digests food, absorbs/conserves water, absorbs nutrients, stores
energy reserves
Urinary system
kidneys, ureters, urinary bladder, urethra
Fn: excretes waste products from blood, controls water balance by regulating volume of
, urine produced, stores urine prior to elimination, regulates blood ion concentration and
pH
Male and Female Reproductive System
Major organs: Male- testes, epididymis, ductus deferentia, seminal vesicles, prostate
gland, penis/scrotum
Female-
ovaries, uterine tube, uterus, mammary glands, vagina, labia, clitoris
Fn: Male-
produces male sex cells (sperm), suspending fluids, and hormones
Sexual intercourse
Female-
Produces female sex cells (oocytes) and hormones
supports developing embryo from conception to delivery
provides milk to nourish newborn infant
sexual intercourse
Proper anatomical position
Person stands erect with feet together and eyes facing forward
Thumbs are away from body
Penis is up
Axial Region
head, neck, and trunk
