Final answer:
The process that describes the movement from glomerular capillaries into Bowman's capsule is known as filtration. This crucial step in urine formation involves the pressure-driven transfer of plasma, sans cells and large proteins.
Step-by-step explanation:
The movement from glomerular capillaries into Bowman's capsule is described as filtration. This process involves the transfer of water and solutes from blood due to the pressure within the glomerular capillaries. As blood flows through these capillaries, part of the plasma is forced across the filtration membrane into Bowman's capsule, forming what is known as filtrate.
The filtrate then enters the proximal end of the renal tubule, where it will eventually be modified into urine through additional processes such as reabsorption and secretion. Notably, reabsorption involves the movement of substances from the filtrate back into the bloodstream, while secretion refers to the process by which certain wastes are added to the filtrate from the blood. Both of these processes occur further down in the renal tubule, not at the stage of glomerular filtration.
