Tissue fluid is formed by high blood pressure forcing fluid out of capillaries, leaving proteins behind. Water returns to the capillaries by osmosis due to the lower water potential created by these proteins.

| Front | Describe how tissue fluid is formed and how it is returned to the circulatory system. ( 6 marks) |
|---|---|
| Back | Formation 1. High blood / hydrostatic pressure / pressure filtration; 2. Forces water / fluid out; 3. Large proteins remain in capillary; Return 4. Low water potential in capillary / blood; 5. Due to (plasma) proteins; 6. Water enters capillary / blood; 7. (By) osmosis; |
