Circulatory System

Circulatory System…
• Moves blood to a site where it
can be deoxygenated and
decomposed of
• Newly oxygenated blood moves
to the tissue of the body
Evolution of the Circulatory System
• The first organisms with a simple circulatory
system including tissue that helped pump the
fluid were protostomes in the Lophotrochozoa
• Around the Cambrian, 600 million years ago
Open Circulatory System
• The blood diffuses
through cells
• Blood does not stay in
veins or vessels
• Common in mollusks
and arthropods
(Just like Robbie!) 
Closed Circulatory System
• The blood is within
vessels of different size
and thickness at all
times
• Is pumped by a heart
through vessels
(Just like Gillbert!)
Evolution in the Closed System
Annelids (Simplest)
-Two main blood vessels
(dorsal and ventral)
-5 pairs of vessels
(“hearts”) that connect
them
Vertebrates (Complex)
-Animals like fish
have two
chambered hearts
-Animals like frogs
have three
chambered hearts
-Humans has four
chambered hearts
Vertebrates- Two Chambered
Heart
– Has an atrium and
one ventricle
– Muscular walls
– Valve between the
chambers
– Blood pumps
through heart then
out to other organs
Vertebrates- Three Chambered
Heart
• Two atria and on
ventricle
• Blood goes through a
forked aorta, which
leads to the lungs and
other organs
• Both atria empty into
the ventricle
Vertebrates- Four Chambered
Heart
• Two atria and two
ventricles
• Blood pumped into first
atrium and oxygenized
in the lungs
• Then pumped through
second atria and fed
through second
ventricle into body for
use
Mammalian Double Circulation
• Type of blood circulation where
blood flows through heart twice.
• The pulmonary and systemic
circulation system.
Pulmonary Circulatory
Systemic Circulatory
• The circulation of blood
through the lungs
• Carries deoxygenated blood
away from the heart and to
the lungs
• Returns from the lungs back
to the heart with
oxygenated blood
• The circulation of blood
from the heart to the body
• Carries oxygenated blood
away from the heart to the
rest of the body
• Returns to the heart with
deoxygenated blood

Lymphatic System
• Consists of organs,
ducts, and nodes
• Transports lymph
• Maintains fluid balance
• Absorbs lipids and
transports them to the
blood
Disorders
• Hypertension: High blood pressure
• Arteriosclerosis: thickening, hardening, and
loss of elasticity of the walls of the blood
vessels
• Rheumatic fever: systemic inflammatory
disease
