Physiology -Lymp
Physiology - Lymphatic/Immune System
| Question | Answer |
|---|---|
| General functions of lymphatic system | 1. Houses and supports immune system 2. Cleans and tops up Cardiovascular system 3. Absorbs fats and fat-soluble vitamins |
| Interstitial fluid is blood plasma which has been forced out of capillaries by | hydrostatic pressure |
| The lymphatic system drains and cleans_________________________ and returns it to the cardiovascular system where it is called blood plasma | interstitial fluid |
| the lymphatic system is a _____________________system (blind-ended) | one way |
| Components of the Lymphatic system (9) | 1. lymph 2. lymph capillaries 3. lymph vessels 4. lymphocytes 5. lymph nodes 6. lymphatic ducts 7. tonsils 8. spleen 9. thymus gland |
| Tissue spaces in the body are known as ________________ | interstitium |
| Once interstitial fluid enters the lymphatic vessels it is called ________________ | lymph |
| Once drained from the lymphatic system, lymph is returned to the cardiovascular system as _________________ | blood plasma |
| Average adult male body contains approximately _________L of water | 40 |
| Of the 40L of water in the average male body, ________L is intracellular fluid | 25 |
| Of the 40L of water in the average male body, ________L is extracellular fluid | 15 |
| Of the 15L of extracellular fluid in the average male body, __________L are interstitial fluid | 12 |
| Of the 15L of extracellular fluid in the average male body, __________L are blood plasma | 3 |
| Where is most of the body's fluid? | intracellular fluid |
| function of lymph capillaries | collect fluid from interstitium that did not return via the veins |
| 4 locations where lymph capillaries are not found | avascular tissue CNS portions of the spleen red bone marrow |
| Lymph capillaries are slightly ________________ in diameter than blood capillaries | larger |
| This type of lymphocyte releases specific antibodies that bond with and neutralize the antigen. Primary target is extracellular pathogens. | B-lymphocytes |
| This type of lymphocyte phagocytoses the antigen; primary target is intracellular pathogens | T-lymphocytes |
| lymph nodes house _________________ that attack foreign bodies (3) | lymphocytes macrophages phagocytes |
