lymphatic vessels
collect fluid from between tissues and return it to the heart
spleen
- filters and destroys red blood cells that are no longer efficient
- serves as a blood forming organ early in life and later as a storage unit for extra red blood cells and platelets
thymus
- located in the neck and extends into the thorax
- present at birth and atrophies slowly after puberty
- responsible for T-lymphocyte maturation, enabling the cells to function against specific pathogens in immune response
tonsils
- partially encapsulated lymphoid tissue located in the throat
- simplest lymphoid vessels
peyer’s patches
found in the lining of the intestine and help protect against invading microorganisms
appendix
finger like projection of tissue attached to the cecum (the first part of the large intestine)

lymphangitis
inflammation of lymphatic vessels as a result of bacterial infection
*appears as painful red streaks under the skin
lymphedema
swelling of tissues with lymph caused by obstruction or excision of lymphatic vessels
