Body

Respiratory
System
Function
 To
supply
the
blood
with
oxygen
in
order
for
the
blood
to
deliver
oxygen
to
all
parts
of
the
body.
Organs

The nose,
throat, lungs,
and
passageways
that lead to the
lungs make up
the respiratory
system

Breathing is made possible by your respiratory system.
The respiratory system is the group of organs that take in
oxygen and get rid of carbon dioxide
Circulatory
System


(Cardiovascula
r)

Your heart creates pressure when it beats. This pressure
moves blood throughout your body.
To
circulate
all
vital
fluids
throughout
the
entire
body
to
nourish
all
of
the
body's
systems;
to
transport
blood,
hormones,
white
blood
cells
and
chemicals
through
the
heart,
lungs
and
all
major
organs.
Your heart,
blood, and blood
vessels make up
your
cardiovascular
system
 to break down the food we eat into
smaller parts so the body can use
them to build and nourish cells and
provide energy
 Your digestive system is a group of organs that work
together to digest food so that it can be used by the
body.
 The liver, gallbladder, pancreas, and salivary glands are
also part of the digestive system. But food does not pass
through these organs.
 The human digestive tract can be more than 9 m long!

The digestive
tract includes
your mouth,
pharynx,
esophagus,
stomach, small
intestine, large
intestine, rectum,
and anus.

Excretory
System



Your urinary system removes waste from blood and
regulates your body’s fluids.
Excretion is the process of removing waste products
from the body. Three of your body systems have a role
in excretion. Your integumentary system releases waste
products and water when you sweat. Your respiratory
system releases carbon dioxide and water when you
exhale. Finally, the urinary system contains the organs
that remove waste products from your blood.
The kidneys are a pair of organs that constantly clean the
blood. Your kidneys filter about 2,000 L of blood each
day. Your body holds only 5.6 L of blood, so your blood
cycles through your kidneys about 350 times per day!
Nervous
System


Immune
System



Your nervous system receives and sends electrical
messages throughout your body.
The nervous system acts as the body’s central command
post. It has two basic functions. First, it gathers and
interprets information. This information comes from
inside your body and from the world outside your body.
Then, the nervous system responds to that information
as needed.

Brain
Spinal cord
(specialized
structures;
nerves)
Also known as the lymphatic system.
Returns leaked fluids to blood vessels and helps get rid
of bacteria and viruses.
The increased blood flow also brings cells that belong to
the immune system, the body system that fights
pathogens. The immune system is not localized in any
one place in your body. It is not controlled by any one
organ, such as the brain. Instead, it is a team of
individual cells, tissues, and organs that work together to
keep you safe from invading pathogens.

Body System
Skeletal System
Function



Muscular System


Your bones provide a
frame to support and
protect your body parts.
Bones, cartilage, and the
connective tissue that
holds bones together make
up your skeletal system.
Bones also help your body
maintain homeostasis by
storing minerals and
making blood cells
Works with the skeletal
system to help your body
move
When you want to move,
signals travel from your
brain to your skeletal
muscle cells. The muscle
cells then contract, or get
shorter.

Protects the tissue that lies Skin
beneath your hair, skin and
nails
Skin protects you by
keeping water in your body
and foreign particles out of
your body.
Skin keeps you in touch
with the outside world.
Nerve endings in your skin
let you feel things around
you.
Skin helps regulate your
body temperature. Small
organs in the skin called
sweat glands make sweat.
Sweat is a salty liquid that
flows to the surface of the
skin. As sweat evaporates,
the skin cools.
Skin helps get rid of
wastes. Several kinds of
waste chemicals can be
removed in sweat.
Skin comes in many
colors. Skin color is
determined by a chemical
called melanin. If a lot of
melanin is present, skin is
very dark. If little melanin
is present, skin is very
light. Melanin absorbs
ultraviolet light from the
sun. So, melanin reduces
damage that can lead to
skin cancer.
Your glands send out
chemical messages
throughout your body
The endocrine system
controls body functions by
using chemicals that are
made by the endocrine
glands. A gland is a group
of cells that make special
chemicals for your body.
Chemical messengers
made by the endocrine
glands are called

Multiple organs
hormones. A hormone is a
chemical messenger made
in one cell or tissue that
causes a change in another
cell or tissue in another
part of the body.
Hormones flow through
the bloodstream to all parts
of the body.

system: produces eggs and
