Across
  1. 6. - (two words, hyphen between them) - system that is involved in preserving fluid balance, transporting foreign materials to lymph nodes for immunosurveillance and transfers fat absorbed in the small intestine to the circulatory system
  2. 9. - (two words, hyphen between them) - structures that can decrease the diameter of a terminal arteriole, causing less blood to pass through capillaries
  3. 10. - unit of a lymph vessel between two semi-lunar valves
  4. 11. - pressure gradient which tends to drive water out of capillaries
  5. 13. - type of capillary present in the liver, bone marrow, spleen; spaces between the endothelium exist, which allow large molecules to diffuse readily
  6. 17. - type of capillary present in kidneys, joints, intestinal mucosa; endothelium contains pores
  7. 18. - (two words, hyphen between them) determined by the permeability of a barrier e.g. reflection coefficient of 0 means that substances can cross a membrane very easily
  8. 19. - higher hydrostatic pressure in the capillary vs the interstitium leads to … of fluid from/to the capillaries
  9. 20. - occurs when net filtration increases (compared to absorption and lymphatic flow) and fluid accumulates in tissue
  10. 21. - route which water mainly flows across to bypass the endothelial wall
Down
  1. 1. - type of capillary present in most tissues; endothelium is one layer covering the entire surface of the capillary; cells joined by tight junctions; least permeable
  2. 2. - protein, capillaries are very impermeable to this protein in order to ensure that blood volume remains stable. (hint - this is the most abundant protein in the body)
  3. 3. - osmotic pressure exerted by electrolytes and other small molecules
  4. 4. - (two words, hyphen between them) - space between adjacent endothelial cells of capillaries; also present in lymphatic capillaries
  5. 5. - (two words, hyphen between them) - part of the lymphatic system, take up fluid, proteins and return them to the blood and transports microorganisms to lymph glands
  6. 7. - part of the vascular system comprising the terminal arterioles, capillaries and post-capillary venules
  7. 8. - pressure gradient created due to substances dissolved in solution. This will cause a movement of water towards the side where this pressure is higher
  8. 12. - (two words, hyphen between them) also known as colloid osmotic pressure. It is the pressure caused by the presence of plasma proteins
  9. 14. - (two words, hyphen between them) describes that the net movement of fluid across an exchange vessel is driven by the overall pressure gradient acting on the fluid
  10. 15. - higher osmotic pressure in the capillary vs in the interstitium leads to … of fluid from/to the capillaries
  11. 16. - glycoprotein layer, covering the luminal surface of the endothelium
