Functions of the Lymphatic System
- Absorb fats and fat-soluble vitamins through the lacteals of the small intestine
- Remove waste products from the tissues and cooperate with the immune system in destroying invading pathogens.
- Return filtered lymph to the veins at the base of the neck.
Lacteals
Specialized structures of the lymphatic system that absorb those fats that cannot be transported through the bloodstream.
Interstitial Fluid
Plasma from arterial blood that flows out of the arterioles into the capillaries and then flows into spaces between the cells of the tissues.
Lymph
Collects the protein molecules created within the cells as it leaves. They also remove dead cells, debris, and pathogens from the intercellular spaces.
Lymphatic capillaries
Separate briefly to allow the lymph to enter the capillary.
Lymphatic vessels
They eventually join together to form two ducts. Each duct drains a specific part of the body and returns the lymph to the venous circulation.
Lymph node
Contains specialized lymphocytes that are capable of destroying pathogens.

Lymphocytes
Work together with the body’s organs to defend the body against antigens.
Antigen
A substance that is foreign to the body.
Natural killer cells
Kill cancer cells and cells infected by viruses.
B cells
Specialized lymphocytes that produce antibodies.
Plasma cells
Develop from B cells and secrete a large volume of antibodies coded to destroy specific antigens.
T cells
Cell-mediated immunity.
Cytokines
Act as intracellular signals to begin the immune response.
Interferons
Activate the immune system, fight viruses by slowing or stopping their multiplication, and signal other cells to increase their defenses.
Interleukins
Directing B and T cells to divide and proliferate.
Tonsils
Three masses of lymphoid tissue that form a protective ring around the back of the nose and upper throat.
Thymus
Secretes a hormone that stimulates the maturation of lymphocytes into T cells.
Spleen
Filters microorganisms and other foreign material from the blood.
-lytic
Destroy
Allergens
Substances that produce allergic reactions.
Malignant cells
Potentially life threatening cancer cells.
Antibody
A disease fighting protein created by the immune system in response to the presence of a specific antigen.
Immunoglobulins
Bond with specific antigens in the antigen-antibody response.
Natural immunity
Resistance to disease present without the administration of an antigen or exposure to a disease.
Acquired immunity
Obtained by having a contagious disease or being vaccinated.
-edema
Swelling
Allergic reaction
Occurs when the body’s immune system reacts to a harmless allergen as if it were a dangerous invader.
Localized allergic response
Redness, itching, and burning where the skin has come into contact with an allergen.
Systemic reaction
Anaphylactic shock/ a sever response to an allergen. The symptoms develop quickly and the patient can die within a few minutes if not treated.
Scratch test
Diagnostic test to identify commonly troublesome allergens.
Allergen-specific immunoglobulin E
Blood test sometimes used to determine whether a person is allergic to a particular substance.
Autoimmune disorder
Any of a large group of diseased characterized by A condition in which the immune system produces antibodies against its own tissues, mistaking healthy cells, tissues, or organs for antigens.
