Bowmanâs capsule is a double-walled, cuplike structure that functions as part of the nephron within the mammalian kidney. It surrounds the glomerulusâa cluster of microscopic capillariesâby enclosing it within its two layers.123
Together, the glomerulus and Bowmanâs capsule form the renal corpuscle. The structure features an open end through which the afferent arterioles enter and the efferent arterioles leave the glomerulus. During the filtration process, blood pressure forces plasma, excluding large macromolecules like proteins, through the inner wall of the capsule and into the nephron tubule.142
