Final answer:
The filtrate is the fluid that passes from the capillaries into the Bowman's capsule and is composed of blood plasma without most of the blood proteins, water, salts, organic solids such as nutrients, and waste products of metabolism. During the filtration stage of nephron function, as blood flows through the glomerular capillaries, water and solutes are filtered out of the blood and into the Bowman's capsule. This filtered fluid is called filtrate. From the Bowman's capsule, the filtrate passes into the renal tubule where further reabsorption and secretion occur before it is eventually excreted as urine.
