1

Lymph

excess tissue containing water and plasma

2

Thoracic duct

serves lower extremities, enters SB vein

3

Right Lymphatic Duct

serves right arm, head and neck, enters right SB vein

4

Spleen

reservoir for blood

5

Red Pulp

contains RBC, lymphocytes, and macrophages

6

White Pulp

forms nodules, both pulps help purify blood

7

Lymph Sinuses

filters bad stuff out of lymph

8

Tonsils

located in pharynx, encapsulated in nodules

Adenoids

pharyngeal tonsils

Lymphoma

cancer of lymphoid tissue

11

Edema

failure of lymphatic vessels to remove tissue fluid

12

ELEPHANTiasis

swelling of arm, leg or external genitals

13

Pulmonary Edema

blood backs up pulmonary circulation

Immunity

ability to defend against disease

17

Pathogens

disease causing agents like bacteria
