Choose the one answer that best describes what normally happens in a capillary bed.
1) Blood colloid osmotic pressure will be lower in the arterial end of the capillary bed compared to the venous end.
2) Blood hydrostatic pressure rises as blood moves from the arterial end to the venous end of the capillary bed.
3) Blood hydrostatic pressure drops as blood moves away from the arterial end to the venous end of the capillary bed.
