Circulatory System
By: Terry Ann Cantu & Mario Lomeli
The circulatory system is an organ system that permits blood
and lymph circulation to transport nutrients, compound for
blood vessels.
The blood vessels are the part of the
circulatory system that transports blood
throughout the body. There are three major
types of blood vessels: the arteries, the
capillaries and the veins.
The Arteries
Blood vessels that carry blood
away from the heart. Most
arteries carry oxygenated
blood.
The Capillaries
This are the smallest of
the blood vessels and
serve as the
connection between
the arterial and venal
systems.
The Veins
Blood vessels that carry blood
toward the heart. Most veins
carry deoxygenated blood from
the tissues back to the heart;
except by the pulmonary and
umbilical veins, both of them
carry oxygenated blood to the
heart.
Blood
Consist of plasma, red blood cells, white blood cells, and
platelets.
Hemoglobin
The hemoglobin is the protein in the blood that
carries oxygen from the respiratory organs to the
rest of the body.
The hemoglobin molecule is the primary transporter
of oxygen, also is the hemoglobin that makes blood
red.
The Heart
Pumps oxygenated blood to the body and deoxygenated blood to
the lungs. In the human heart there is one atrium and one ventricle
for each circulation, and with both a systemic and a pulmonary
circulation there are four chambers in total: left atrium, left ventricle,
right atrium and right ventricle.
Coronary Circulation
Coronary circulatory system provides a blood supply to
the myocardium (the heart muscle). It arises from the
aorta by two coronary arteries, the left and the right, and
after nourishing the myocardium blood returns through
the coronary veins into the coronary sinus and from this
one into the right atrium.
Systemic Circulation
Systemic circulation is the circulation of the blood to all
parts of the body except the lungs.
Pulmonary Circulation
The pulmonary circulatory system is the portion of the
cardiovascular system in which oxygen-depleted blood is
pumped away from the heart, via the pulmonary artery, to the
lungs and returned, oxygenated, to the heart via the pulmonary
vein.
