Document Summary
Mucous associated lymphatic tissue (malt) up: explain the formation of the lymph. The lymphatic vessels carry the interstitial fluid, lipids, cell debris (except from nervous system), lymphocytes (wbc) => lymph: name the lymphatic organs and explain their main functions. Lymphatic system: lymph = fluid, lymph vessels, lymph organs: spleen, tonsils, red bone. Are in all human organs except cns, eyeball, inner ear + cartilages. Duct then drain into venous system @ border of subclavian vein. Are in groups, next to deep + superficial veins. Lots of them in axilla, neck, popliteal fossa (kneepit), inguinal region, post abdominal wall, mediastina. Axillary lymph node: for upper limb, upper quadrant of abdomen + chest wall. Perineal lymph node: drain into inguinal lymph node. Pelvic lymph node: drain into lumbar lymph nodes. Medial/visceral surface: next to stomach, left kidney, has hilum (autonomic nerves, splenic artery, splenic vein, efferent lymphatic vessels) Invasion of foreign invades happen here, so lots of immune cells here.
