1. In table form give the functions of each blood cells, blood vessels and heart. (15 pts)
Red Blood Cells
or Erythrocyte
It transports oxygen and carbon dioxide
throughout the body. It consists of a
protein network and a red pigment of
hemoglobin.
Neutrophils
The most common granular leukocyte that
responds to damaged tissue from bacteria
by phagocytizing the foreign substances.
It destroys bacteria through their enzyme
lysozyme.
Eosinophil
It produces antihistamine. They are
granular leukocytes that fight off irritants
that cause allergies as well as parasitic
worms.
Basophil
Basophils are also involved in allergic
reactions. It produces histamine, heparin,
and serotonin.
Monocyte
A nongranular leukocyte that
phagocytizes bacteria and cellular
debris.
B Lymphocyte
Responsible for the antibody production.
T Lymphocyte
It is in charge of cellular immune response
in the circulatory system.
Platelets
It prevents fluid loss when the blood
vessels are damaged by the chain of
reaction that results in blood clotting.
Blood Vessel
It serves as the channel in which blood is
being distributed into the body tissues.
Arteries
The function of arteries is to transport the
blood away from the heart.
Arterioles
It delivers blood to the capillaries and
regulates the blood flow to the tissue
capillaries.
Veins
Veins adapt to the variation of blood
pressure and volume. It ensures the blood
flow in one direction towards the heart.
Venules
Its function is to collect blood from the
capillaries and eventually drain it into the
veins.
Capillaries
It allows the exchange of nutrients such
as oxygen and carbon dioxide as well as
waste between blood and tissue cells of
the body.
Heart
It distributes enough blood to deliver an
adequate continuous supply of oxygen as
well as nutrients into the brain and other
parts of the body.
