At the arterial end of a capillary, the hydrostatic pressure is higher than the pressure exerted by the water potential gradient, resulting in a net loss of water from the capillary.

| Front | Explain why there is a net loss of water from a capillary at the arterial end. ( 2 marks) |
|---|---|
| Back | (at arterial end) hydrostatic pressure/blood pressure; greater than pressure of water potential gradient /greater than osmotic uptake; |
