The Circulatory
System
The Circulatory System
•
The circulatory system consists
of the heart, arteries, veins and
capillaries, and the blood. All of
the other systems in the body
rely on the circulatory system,
except for the skeletal system.
What is the Circulatory
System?
•
The circulatory system carries
blood throughout the body. The
heart is the main control of the
circulatory system. Without the
heart, we would die. If the blood
doesn’t go throughout the body,
the brain doesn’t get the blood
to function properly.
What Blood Does
The blood transports oxygen,
nutrients, wastes, and carbon dioxide
throughout the body. When you
breath oxygen, the oxygen goes
down your trachea, which splits up
into smaller tubes that end in tiny air
sacs called alveoli. Since the walls of
alveoli are only one cell thick,
oxygen can diffuse through the walls
into the capillaries. The capillaries
get blood from the pulmonary
arteries and transport the oxygen to
the rest of the body through the
blood. The capillaries also transport
nutrients, carbon dioxide, and wastes
to and from the body.
Capillaries
The capillaries get blood from
the pulmonary arteries and
transport the oxygen to the rest
of the body through the blood.
The capillaries also transport
nutrients, carbon dioxide, and
wastes to and from the body.

HOW YOUR RESPIRATORY
SYSTEM WORKS
FACTS ABOUT YOUR LUNGS
LUNGS
Your body needs lots of
oxygen to survive. First air
goes down the trachea, also
known as your windpipe. Then
the air goes into branch-like
tubes in your lungs called
bronchi. As the air goes into
bronchi the air goes through
smaller and smaller tubes. At
the end of the smallest tubes
there are little air sacs called
alveoli.
MORE FACTS ABOUT LUNGS
• You and your systems need oxygen to keep
running. The respiratory system is what gets
the oxygen. When you breathe, warm air
goes down down your trachea and into your
lungs. The trachea connects to bronchi,
which divides into smaller tubes.

The Skeletal System
The skeletal system
works when joints
attach bones to each
other and to muscles,
ligaments hold the
skeleton together, and
tendons attach bones
to muscles.
What Does the Skeletal System
Do?
The Skeletal System controls
the body movement along with
the muscles. The hinge joints
allow you to bend and
straighten your arms and legs.
What allows the circular
motion is the ball-and-socket
joint. For example:your hips
and your shoulders are balland-socket joints.
The Bones of Your Skeletal
System Are…….
The skull, clavicle,
sternum, ribs,
humerus, spine,
pelvis, femur,
patella, fibula, tibia,
phalanges (fingers
and toes), radius,
ulna.
Muscular System
Muscles help your body move.
Without them you wouldn’t be
able to do anything. The more
weight you put on a muscle, the
bigger and stronger it gets.
THE IMPORTANCE OF
MUSCLES
• Muscles are one of the
most important body
parts. You couldn’t
hand shake without
them.

The Nervous System
The nervous system consists of two
parts: the central nervous system and
the peripheral nervous system.
The Central Nervous System
The central nervous
system decodes signals
it accepts from nerves
and decides what reply
is needed. Signals sent
by the brain travel
through nerves and
conduct all of the
body’s muscles.
The Peripheral Nervous
System
The peripheral nervous
system consists of
sensory organs, like the
eyes and ears,and body
nerves. Nerves have
bundles of cells called
neurons, which are
specialized cells that can
receive signals and convey
them to other neurons.

The Digestive and the Excretory
Systems
You couldn’t live without them!
The Digestive System
• The digestive system
is a system in your
body that lets you eat.
• It also produces the
nutrients in your cells
need to produce
energy.
The Excretory System
• The wastes of the
body are taken out of
the body in the
excretory system.
