WebSubstances are moved from the blood to the tubular fluid. Substances move from the tubules then bladder to the external environment. Substances are moved from the tubules into the blood. Substances are pushed from the glomerulus into the capsule. A Identify the major processes essential to urine production. Select all that apply. Filtration WebKidneys filter blood in a three-step process. First, the nephrons filter blood that runs through the capillary network in the glomerulus. Almost all solutes, except for proteins, are filtered out into the glomerulus by a process called glomerular filtration. Second, the filtrate is collected in the renal tubules.
