The forced movement of fluid and small materials out of the glomerulus?

Answer 1

The difference between the diameter of afferent and efferent glomerular artery and angiotensin and renin create a condition, coupled with high blood pressure lead to a condition whereby the solutes of low molecular weight pass down the glomerulus and come down the proximal tubule.

Answer 2

its urine formation that comprises:
1,- filtration of the filtered plasma through the glomerular membrane. by means of the plasma hydrostatic pressure (filtration)..
2.-excretion and reabsorption of water, and electrolytes
3.- excretion of excess waste products by secretion (urea creatinine uric acid etc)
4.- reabsorption of components that need to be saved in the body, like water, potassium etc
5,. The net filtration will give you URINE at the end of collector tubules (tubules of Bellini)

Answer 3

Glomerular filtration.

Answer 4

glomerular filteration in kidneys, due to many pressure-concentration related mechanisms, though podocyte cells, which do not give enough space for large cells to pass through
