what does the glomerulus include
Glomerular Filtration. The first step in renal processing involves the filtration of plasma in the glomerulus. Glomerular filtration is a process of bulk flow: water and low molecular weight substances move from the lumen of the capillary, across the filtration membrane, and into Bowman s space.his includes various polar organic molecules such as glucose or amino acids, ions, peptides, drugs, and waste products of organic metabolism such as creatinine and urea. Because filtration involves bulk flow, the concentration of a substance in Bowman s space will be the same as its concentration in the plasma.
