Chapter 15- Lymphatic Flashcards
Destroy foreign proteins
Antibodies/immunoglobulins
A type of immunity acquired naturally when exposed to a bacterium or virus or aquired artificially through a vaccine
Active immunity
Foreign proteins that gain access to our bodies through cuts and scrapes, digestive or circulatory system
Antigens
Cells that produce antibodies and provide humoral immunity; also known as B cells
B lymphocytes
Results of the body’s lymphoid tissue
Cellular immunity
Lymph in the lacteals that has a high fat content and looks milky
Chyle
Swelling
Edema
Stimulate the production of killer T cells and more B cells to fight invading pathogens
Helper T cells
Results of the body’s lymphoid tissue
Humoral immunity
The ability of the body to resist infection from disease-causing microorganisms
Immunity
Blood plasma found in the spaces between tissue cells
Interstitial fluid
Types of lymphocytes that kill virus-invaded body cells and cancerous body cells
Killer T cells
Lymphatic vessel that absorbs fats and transport them from the digestive tract to the blood
Lacteals
The name given to interstitial fluid when it enters a lymphatic capillary
Lymph
Blind end tubes that are the origin of lymphatic vessels
Lymphatic capillaries
Lymph node, lymph gland
Lymph nodes/ glands
Chemicals released by the sensitized t lymphocytes
Lymphokines
Engulf and digest antigens; monocytes
Macrophage
Descendants of activated T and B cells
Memory cells
Tonsils commonly removed in a tonsillectomy
Palatine tonsils
Occurs naturally when a fetus received its mothers antibodies through the placenta
Passive immunity
One of two collecting channels or ducts of the lymphatic system
Right lymphatic ducts
The largest single mass of lymphatic tissue
Spleen
Main collecting duct of the lymphatic system
Thoracic duct
An endocrine gland located beneath the sternum that is also involved in immunity as a site for lymphocyte production and maturation
Thymus gland
T cells; responsible for providing cellular immunity
T lymphocytes
Hypersensitive reactions to common, normal, usually harmless environmental substances referred to as allergens
Allergies
A tumor of lymphatic tissue, malignant
Lymphoma
An inflammation of lymph nodes or glands
Lymphadenitis
Inflammation of the lymphatic vessels with accompanying red streaks visible in the skin
Lyphangitis
Acquired immune deficiency syndrome; caused by infection w the human immunodeficiency virus HIV
AIDs
Chronic inflammatory disease in which cells and tissues are damaged by the immune system
Systemic lupus erythematosus (SLE)
