Blood System Overview
 Blood circulates through blood vessels to:
 transport oxygen, nutrients and hormones to body cells
 carry away waste
 Plasma — liquid portion of the blood
Blood System Overview
(continued)
 Cellular components suspended in the plasma:
 erythrocytes — red blood cells
 leukocytes — white blood cells
 platelets — cell fragments essential for blood clotting
 Serum: portion of the plasma that remains after
the clotting process
Components of the Blood
Lymphatic System Overview
 Protects the body by filtering microorganisms and
foreign particles
 Maintains the body’s internal fluid environment
 Responsible for carrying fats away from digestive
organs
Lymphatic System
Lymph Organs
 thymus
 primary gland of the lymphatic system
 produces T lymphocytes to help immune response
 spleen
 located between stomach and diaphragm
 filters out aging blood cells
 removes cellular debris
Lymph Structures
 lymph
 fluid that is circulated through lymph vessels
 lymph capillaries
 draw lymph from tissues to lymph vessels
 lymph vessels
 circulate lymph to the lymph nodes
Lymph Structures
(continued)
 lymph nodes
 oval structures that filter lymph
 located in the cervical, axillary and inguinal regions
 lymph ducts
 collecting channels that carry lymph from the lymph
nodes to the veins
Immunity
 Process of disease protection induced by exposure
to an antigen
 antigen — substance that, when introduced into the
body causes formation of antibodies against it
 antibody — substance produced by the body that
destroys or inactivates an antigen
Types of Immunity
 Active immunity
 Protects the body against a future infection as a result
of natural antibodies developed after an infection
 artificial antibodies — after administration of a vaccine
 Passive immunity
 conveyed naturally through the placenta to a fetus
 conveyed artificially by injection of a serum containing
antibodies
