What process describes the movement of water and dissolved substances from glomerular blood into Bowman's capsule?

The movement of water and dissolved substances from glomerular blood into Bowman's capsule is known as filtration. This process occurs in the kidneys, specifically in the renal corpuscle, where blood flows through the glomerulus, a network of capillaries. The high pressure in the glomerulus forces water and small solutes, such as electrolytes, glucose, and waste products, through the capillary walls and into the Bowman's capsule, while larger molecules like proteins and blood cells remain in the bloodstream.

Filtration is essential for the initial step of urine formation, as it allows the body to remove waste products while retaining useful substances in the bloodstream. This process sets the stage for further modifications through reabsorption and secretion as the filtrate progresses along the nephron.
