TRANSPORT
SYSTEM
BY ROLAND
SAYAGO
LESSON OBJECTIVES
01
Explain the relationship
between circulatory and
respiratory system;
02
Identify the parts and
functions of human circulatoy
system;
03
Trace how blood circulates in
the body.

VESSELS
BLOOD VESSELS
Artery
The arteries are the
blood vessels that deliver
oxygen-rich blood from
the heart to the tissues
of the body.
Vein
The veins are the blood
vessels that deliver nonoxygenated blood
towards the heart.
BLOOD VESSELS
Arterioles &
Venules
Arterioles and venules
are small diameter blood
vessels that allow blood
flow to and from
capillary beds,
respectively.
BLOOD VESSELS
Capillaries
Capillaries are delicate
blood vessels that deliver
blood, nutrients and
oxygen to cells
throughout the body.
BLOOD
BLOOD
The red liquid that
circulates in the arteries
and veins of humans and
other vertebrate animals,
carrying oxygen to and
carbon dioxide from the
tissues of the body.
PLASMA
Makes up about 55% of
the body's total blood
volume. Helps with
immunity, blood clotting,
maintaining blood
pressure, blood volume,
and pH balance in the
body
RED BLOOD
CELLS
Red blood cells are the most
common type of blood cell
and the vertebrate's
principal means of delivering
oxygen to the body
tissues—via blood flow
through the circulatory
system.
WHITE BLOOD
CELLS
White blood cells are part of
the body's immune system.
They help the body fight
infection and other diseases.
PLATELETS
Platelets are tiny blood cells
that help your body form
clots to stop bleeding.

HEART
HEART
Your heart is the primary
organ of your circulatory
system. It pumps blood
throughout your body,
controls your heart rate and
maintains blood pressure.
VALVES
The valves are made of
strong, thin flaps of tissue
called leaflets or cusps. The
leaflets open to let blood
move forward through the
heart during half of the
heartbeat. They close to
keep blood from flowing
backward during the other
half of the heartbeat..
PARTS OF THE
HEART
The right side of the
heart receives
deoxygenated blood
collected from different
parts of the body
The left side of the
heart receives
oxygenated blood
from the lungs
PARTS OF THE
HEART
The two atria are thinwalled chambers that
receive blood from the
veins.
The two ventricles
are thick-walled
chambers that
forcefully pump
blood out of the
heart.
PARTS OF THE
HEART
The Vena Cava is a
large vein that carries
blood to the heart from
other areas of the
body.
The Pulmonary Vein
collects the oxygenated
blood and carry it from
the lungs back to the
heart.
The Pulmonary Arteries
carry blood from the
right side of the heart to
the lungs.
The Aorta is the main
artery that carries blood
away from your heart to
the rest of your body.

Organs of
Respirati
on
Nose
Air enters the nostrils, which
are lined with tiny hair, called
cilia, and mucus membranes
all of which filter dust
particles from the air we
breathe.
Pharyn
x
The pharynx is the common
opening for food that we
swallow and air that we
inhale. A flap muscle called
epiglottis guards the path of
the pharynx to ensure that
food and air will enter their
respective destinations.
Larynx
The hollow muscular organ
forming an air passage to
the lungs and holding the
vocal cords in humans and
other mammals - the voice
box.
Trachea
Bronchi
Bronchiole
s
Air
Sac
Each air sac consists of many
tiny out-pocketing called
alveoli. It is within the alveoli
that the gas exchange
occurs
The Breathing
Process
Breathing is the process of drawing air
into the lungs (inhalation) and its
corresponding (exhalation).
