Ch 2.4 Lymph/Resp.Diges Flashcards
(15 cards)
Lymphatic system
Manages fluids in the body and returns appropriate fluids to the heart via lymph nodes/vessels. Includes the spleen, thymus, tonsils, Peyer’s patches of the intestines.
Spleen
Filters & destroys red blood cells that are no longer efficient.
Thymus
After puberty, the thymus gradually atrophies. Is responsible for T-lymphocyte maturation for immune responses.
Tonsils
Partially encapsulated lymphoid tissue.
Peyer’s Patches
Found in the lining of the intestine containing high levels of white blood cells.
Repiratory system
Includes the nose, nasal cavity, pharynx, larynx, trachea, bronchi, lungs, and alveoli.
