What forces the fluid from the capillaries of the glomerulus into the Bowman's capsule?

Blood pressure forces plasma minus its macromolecules (e.g., proteins) from the glomerular capillaries into the Bowman's capsule, which is continuous with the proximal convoluted tubule.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
