Now, the glomerulus and the Bowman capsule together is known as the renal corpusol. And we see that along the renal corpusol we have the process of filtration taking place. So the glomerulus is a network of capillaries that receives the blood from the African arterial filtration initiates in this section here, a high hydrostatic pressure in the glomerulus as a result of that movement of blood through these small capillaries forces relatively small and positively charged particles such as sodium, potassium, amino acids, glucose and so forth across this region and into a section known as the Bowman's capsule. Now, relatively large molecules such as protein molecules such as albumin, as well as things like red blood cells, are too large to actually pass across the pores that are found within this section. And so larger molecules do not actually pass across and into the Bowman's capsule. Now, about 20% of the blood plasma that enters this region, it's filtered into the Bowman's capsule.
