Human Body Systems
Organization of The Body


The eleven organ systems of the human
body work together to maintain
homeostasis
Homeostasis – process which organisms
maintain a relatively stable internal
environment

Nervous System


Brain, Spinal cord, periperal nerves
Function: Coordinates the body’s
response to changes in its internal and
external environments

Integumentary System


Skin, hair, nails, sweat and oil glands
Function: Serves as a barrier against
infection and injury; helps to regulate
body temperature; provides protection
against ultraviolet radiation from the
sun

Respiratory System


Nose, pharynx, larynx, trachea, bronchi,
bronchiales, lungs
Function: Provides oxygen needed for
cellular respiration and remove excess
carbon dioxide from the body

Digestive System


Mouth, pharynx, esophagus, stomach,
small and large intestine
Function: Converts foods into simpler
molecules that can be used by the cells
of the body; absorbs food

Excretory System


Skin, lungs, kidneys, ureters, urinary
bladder, urethra
Function: Eliminates waste products of
metabolism from the body; maintains
homeostasis

Skeletal System


Bones, cartilage, ligaments, tendons
Function: Supports the body; protects
internal organs; allows movement;
stores mineral reserves; provides a site
for blood cell formation

Circulatory System
Muscular System


Skeletal muscle, smooth muscle, cardiac
muscle
Function: Works with skeletal system to
produce voluntary movement; helps to
circulate blood and move food through
the digestive system

Circulatory System


Heart, Blood vessels, blood
Function: Brings oxygen, nutrients, and
hormones to cells; fights infection;
regulates body temperature

Endocrine System


Hypothalamus, pituitary, thyroid,
parathyroids, adrenals, pancreas,
ovaries(in females), testes (in males)
Function: Controls growth,
development, metabolism, and
reproduction

Reproductive System


Testes, epididymis, vas deferens,
urethra, and penis (in males); Ovaries,
fallopian tubes, uterus, vagina (in
females).
Produces reproductive cells; in females,
nurtures and protects developing
embryo

Lymphatic System


White blood cells, thymus, spleen,
lymph nodes, lymph vessels
Helps protect the body from disease;
collects fluid lost from blood vessels and
returns the fluid to the circulatory
system.
