| Left thoracic duct drains into: | L subclavian vein | (blank) |
| Lymphatic sys provides a mechanism for: | collection & return of fluids | that have escaped from blood vascular sys |
| Functions of lymphatic are: 3 | 1)production, maint & distribution of lymphocytes | (blank) |
| 2nd function of lymphatic: | RET OF FLUID & SOLUTES FROM PERIPHERAL TISSUES TO THE bLOOD STREAM | (blank) |
| 3RD FUNCTION: | dist. of hormones, nutrients & waste prod. from their of origin to the gen circulation | (blank) |

| lymphatics transport fats as: | chylomicrons and/or chyle | (blank) |
| chyle is | LYMPT PRODUCED BY LACTEALS | (blank) |
| COLOR OF CHYLE/WHY | MILKY white | due to fat content from intestinal digestion of fats from the digestive tract of the blood |

| lymphatic mechanisms for return are: | use of valves, pressure changes during breathing, | milking action of skeletal muscles & action of smooth muscles in BV walls |
| Lymphedema | blockage of lymphatics prevents return of fluid. | causes swelling & pain; common after surgery, |
| Lymphangitis | inflammation of super ficial lymphatic vessels | (blank) |
| Hodgkin's disease | Malignancy of the lymph nodes | cancer; usually curable |
| Mono nu cleosis | viral disease caused byEpstein-Barr (EBV) virus. | EBV invades B-lymphocytes & causes lg #'s of T-lymphocytes to go into attack mode |
