lacteals

10. ___ are specialized lymphatic capillaries in the villi of small intestine that allow for the absorption of lipid-soluble substances from the GI tract (of the small intestine). (Textbook.826/21.01)

villi, lipid-soluble

endothelium

16. a lymphatic capillary resembles blood capillaries in that their walls are composed of an ___. (Textbook.824/21.01)

larger, basement membrane, endothelial cells

17. lymphatic capillaries and blood capillaries differ in that lymphatic capillaries are ___ (smaller/larger), lack ___ and have overlapping ___ (cells). (Textbook.824/21.01)

endothelial cells

18. overlapping ___ (pl.) of lymphatic vessels act as one-way flaps (doorways) that allow fluid to enter and not leave. (Textbook.824/21.01)

lymphatic capillaries

19. ___ (capillaries) are interspersed throughout areolar connective tissues. (Textbook.824/21.01)

lymphatic vessels

2. ___ (vessels) return IF back to the vascular system. (Slide.1/21.01)

lacteal

21. what is this a picture of.? (Slide.8/21.01)

23. label the diagram 1-5 (Slide.4/21.01)

15%

24. approximately __(%) of the lymph that enters the IF surrounding the cells is not reabsorbed back into the blood capillaries during capillary exchange. (Textbook.824/21.01)

areolar connective tissues

24. lymphatic capillaries are found throughout ___ (tissues). (Textbook.825/21.01)

3 liters

25. lymph amounts to about __ (liters) daily and is normally absorbed into lymphatic capillaries. (Textbook.824/21.01)

25. lymphatic capillaries are absent from ___ (tissues) (red bone marrow and the central nervous system). (Textbook.825/21.01)

lymphatic vessels

26. IF becomes lymph once it enters the ___. (Textbook.824/21.01)

lymph

27. once interstitial fluids are inside lymphatic vessels, they are called ___. (Textbook.824/21.01)

vascular system

3. the lymphatic vessels return IF back to the ___ (system). (Slide.1/21.01)

capillaries

4. lymphatic vessels are found near ___. (lecture/21.03)

1 capillaries, 2 collecting vessels, 3 trunks, 4 ducts

5. the 4 types of lymphatic vessels are and, consequently, the overall flow of their drain is (plural): 1 lymphatic ___ 2 lymphatic ___ 3 lymphatic ___ 4 lymphatic ___ (Slide.1/21.01)

1 semicircle, 2 circle, 3 like a vein, 4 vein, 5 has valves, 6 has valves, 7 no heart, 8 heart, 9 low pressure, 10 like a vein

6. complete the graph of the differences between Lymphatic and Cardiovascular system. (---/21.01)

lymphatic capillaries

7. ___ are the smallest, closed-ended, vessels that absorb excess tissue IF from around the cell to be filtered and returned to the venous circulation. (---/21.01)

fluids, venous circulation

8. the main purpose of the lymphatic capillaries is to drain excess tissue ___ (pl.) from around the cell, to be filtered, and then returned to ___ (circulation type). (---/21.01)
