Nervous System
Structures:
Brain, spinal cord, and
peripheral nerves
Function:
Coordinates the body’s
response to changes in its
internal and external
environments
4
Digestive System
Structures: Mouth, pharynx,
esophagus, stomach, small
intestines and large intestines
Function: Converts foods into
simpler molecules that can be used
by the cells of the body; absorbs
food
5
The digestive system does not work
without the help of other organ
systems.
The digestive system needs the cardiovascular
system to deliver the nutrients to other organs in
the body such as the muscles and the brain.
6
Circulatory System
Structure: Heart, blood vessels, and
blood
Function: Brings oxygen, nutrients,
and hormones to cells; fights
infections; and regulates body
temperature
7
Respiratory System
Structures: Nose, pharynx, larynx,
trachea, bronchi, bronchioles, and
lungs
Function: Provides oxygen needed
for cellular respiration and
removes excess carbon dioxide
from the body
8
The circulatory system
depends on the pulmonary
system (lungs) to deliver
oxygen to muscles and other
organs.
9
Skeletal System
Structures: Bones, cartilage,
ligaments, and tendons
Function: Supports the body; protects
internal organs; allows movement;
stores mineral reserves; and provides
a site for blood cell formation
10
Muscular System
Structures: Skeletal muscle, smooth
muscle, and cardiac muscle
Function: Works with skeletal system
to produce voluntary movement;
helps to circulate blood and move
food through the digestive system
11
Muscles and bones work together to
produce movement.
12
Excretory System
Structures: Skin, lungs, kidneys,
ureters, urinary bladder, and urethra
Function: Eliminates waste products
of metabolism from the body and
maintains homeostasis
13
Integumentary System
Structure: Skin, sweat and oil glands, hair, and nails
Function: Serves as a barrier against infection and injury; helps to regulate body
temperature; and provides protection against ultraviolet radiation from the sun
14
Lymphatic System
Structures: White blood cells,
thymus, spleen, lymph nodes, and
lymph vessels
Function: Help protect the body
from disease; collects fluid lost from
blood vessels and returns the fluid
to the circulatory system
15
Getting rid of waste is another necessary
function of the body:
• Lungs get rid of carbon dioxide.
• Lymphatic vessels recycle extra fluids
that build-up next to cells and tissues.
• Kidneys filter the blood of toxins.
• Skin releases excess salts through
sweat.
16
Endocrine System
Structures: Hypothalamus, pituitary
gland, thyroid, parathyroid,
adrenals, pancreas, ovaries (female),
and testes (male)
Function: Controls growth,
development, metabolism and
reproduction
17
Reproductive System
Structures: Testes, epididymis, vas
deferens, urethra, and penis (males);
ovaries, Fallopian tubes, uterus, and
vagina (females)
Function: Produces reproductive cells, in
females, nurtures and protects developing
embryo
• Reproduction, growth and
development are critical functions of all
living things.
• The endocrine system provides the
chemical messages for growth,
development, and proper functioning
of the reproductive system.
