Study Notes
Blood Flow into Glomerulus
- Blood flows into the glomerulus through the afferent arteriole, which is much larger than the efferent arteriole
- Blood flows in faster
- Blood cells and most plasma proteins are too large to pass through the pores
Filtration
- The fluid that has filtered into Bowman's capsule flows into the renal tubules
- The amount of fluid filtered by both kidneys is about 180 liters each day. This is called the Glomerular Filtration Rate (GFR).
