contain lymphocytes and macrophages that fight pathogens

Originates in abdomen and empties into left subclavian vein

Fluid Balance, Lipid Absorption, Defense

Skin, mucous membranes, hair, tears, saliva. urine

cancer of the lymph nodes

largest lymphatic organ;divided into lobules

Located along lymphatic pathway;contains lymphocytes and macrophages that fight pathogens

Drain lymph from the lymphatic vessels

gastric juice, salt from perspiration

swelling due to lymph node blockage

Excess tissue fluid

Found in tonsils;masses of lymphocytes and macrophages in cortex

Transports excess fluid away from space in tissue and returns it to the bloodstream

Ex.Humans are resistant to forms of malaria that effect birds.

enlargement of the lymph nodes

Force which moves tissue fluid into capillaries

Vessels that drain the scalp, face, nasal cavity, and pharynx

Absorption of dietary fats, transports bacteria and virus to lymph nodes

Defend body against various viruses and cancer cells, secretes perforins

Small bits of debris catches on the tonsils and white blood cells attack the debris and leave behind hard a hard biofilm that breaths oxygen

Stimulates maturation of T lymphocytes

Enclosed in connective tissue in mediastinum;soft bilobed gland

Provides complex network of chambers and channels in which lymph circulates

peptides produces in response to virus or tumor cells

multiple cysts or lesions formed from lymphatic vessels, genetic mutation
