Kidney Function: Ultrafiltration Process is a document available to read on EtoBox.
The kidneys filter blood through a process called ultrafiltration. Blood enters the glomerulus under high pressure due to the narrowing of the efferent arteriole, which forces water and dissolved molecules smaller than 70,000 Daltons into the renal capsule. The filtrate then passes through the endothelial cell pores in the capillary walls, the basement membrane, and is collected by the podocytes in the renal capsule before exiting as urine. The kidneys are adapted for efficient filtration, with pores that d
