Artery
The arteries are the blood
vessels that deliver oxygenrich blood from the heart to
the tissues of the body.
Vein
The veins are the blood
vessels that deliver nonoxygenated blood towards
the heart.
Arterioles & Venules
Arterioles and venules are
small diameter blood vessels
that allow blood flow to and
from capillary beds,
respectively.
Capillaries
Capillaries are delicate blood
vessels that deliver blood,
nutrients and oxygen to cells
throughout the body.
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.
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 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 are part of the
body's immune system. They
help the body fight infection and
other diseases.
Platelets are tiny blood cells that
help your body form clots to
stop bleeding.

Your heart is the primary organ
of your circulatory system. It
pumps blood throughout your
body, controls your heart rate
and maintains blood pressure.
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..
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
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.
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.

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.
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.
The hollow muscular organ
forming an air passage to the
lungs and holding the vocal cords
in humans and other mammals the voice box.
Each air sac consists of many
tiny out-pocketing called alveoli.
It is within the alveoli that the
gas exchange occurs
Breathing is the process of drawing air into
the lungs (inhalation) and its corresponding
(exhalation).
