Tissue Fluid Formation

Question 1

What is the first step of tissue fluid formation?

Answer 1

• At the arteriole end
• Outward blood pressure is greater than the inward water potential
• Caused by the effect of plasma proteins

Question 2

What is the second step of tissue fluid formation?

Answer 2

• Water ions and small molecules
• Filtered/forced out of the blood
• Into spaces between cells

Question 3

What is the third step of tissue fluid formation?

Answer 3

• Loss of fluid in blood
• Lead to fall in blood pressure
• Approaches the venule end

Question 4

What is the fourth step in tissue fluid formation?

Answer 4

• At the venule end
• Osmotic pull exceeds outward blood pressure
• Some water re-enters capillary via osmosis
• Down a conc gradient

Question 5

What is the final step of tissue fluid formation?

Answer 5

• Tissue fluids drain away from cells
• Via lymph vessels
• Returned to circulation near the heart
