Vet Med Term. Ch 15: Feed and Protect Me (Lymphatic System)

The combining forms — means lymph fluid, lymph vessels, and lymph nodes.

Lymph/o

— pertatins to lymph or tissue of the lymphatic system

Lymphoid

— is the clear, coloerless tissue fluid that leaves the capillaries and flows in the spaces between the cells of a tissue or an organ

Interstitial fluid

— is formed when interstital fluid moves into the capillaries of the lymphatic system

Lymph

Lymph is carried from the tissue space via thin walled tubes called —

Lymph capilliaries

— are similar to veins in that they have valves to prevent the backflow of lymph (lymph only flows in one direction)

Lymphatic veseles

The — is the origin of the thoracic duct and saclike structures for the lymph collection

Cisterna chyli

— located in the small intestines, are specilized lymph vessels that transport fats and fat soluble vitamins

Lacteals

— are small bean shaped structures that filter and store B and T lumphocytes

Lymph nodes

The — are masses of lymphatic tissue that protects the nose and cranial throat

Tonsils

Combining form: Tonsill/o

The — is the organ located in the cranial adbomen that filters foreign material from the blood, stores erythocyters, removes damaged or old erythrocyters and maintains an appropriate balance of cells and plasma in blood.

Spleen

The combining form — means spleen

Splen/o

The — is a gland that has an immunologic function and is found predominantly in young animlas.

Thymus

The term — come from the Latin term immunitas, which means exemption

Immunituy

The combining from — means protected

immun/o

— is the study of the immune system

Immunology

The — is a type of white blood cell that is involved in the immune responce and works aginist specific antigens

Lymphocyte

— are responsible for cell mediated immunity and — are produced and mature in the bone marrow and are responsible for antibody-mediated or humoral immunity

T Lymphocytes

B Lymphocytes

A — is an immune cell that produces andsecretes a specific antibody for a specific antigen; also called Plasmocytes

Plasma cell

The antibodies made by plasma cells are called —

Immunoglobulins

Abbreviated: Ig

T lymohocytes are small, circulating lymphocytes produced in the bone marrow. Theses cells mature in the thymus, so they are called —-

T Cells

secrete substances such as cytokines that stiumlate the production of B lymphocytes and cytotoxic T cells

Helper T cells

Also known as CD4 cells

— destory intracellular pathogens

Cytotoxic T cells

Also know as CD8

— stop B and T lymphocyte activity when this acitivty is no longer needed

Suppressor T cells

— remember a specific antigen when that same antigen is presented to the body

Memory T cells

A — is a phagocytic cells that protects the body by engulfing invading cells and by interacting with other cells of the immune system

Macrophage

— are large macrophages found in loose connective tissue

Histiocytes

— is a series of enzymatic proteins that are continually present in normal plasma

Complement

— is the state of being resistant to a specific disease

Immunity

= resistance to a specific infection by the passing of protection from mother to offspring before birth or through colostrum

Naturally acquired passive immunity

= resistance to a specific infection after the development of antibodies during the actual disease

Naturally acquired active immunity

= resistance to a specific infection by receiving antiserum containing antibodies from another host

Artificially acquired passive immunity

= resistance to a specific infection through vaccination

Artificially acquired active immunity
