The structure of nephron comprises two major portions A Renal Tubule B Renal Corpuscle Renal corpuscles it consists of a glomerulus surrounded by a Bowmans capsule The glomerulus arises from an afferent arteriole and empties into an efferent arterioleA considerable amount of the blood plasma filters through the glomerulus into the nephron tubule This results from the large amount of blood flow through the glomerulus the large poresin the glomerular capillaries and the hydrostatic pressure of the blood Red blood cells and large proteins such as serum albumins cannot pass through the glomerulus under normal circumstances Small molecules including water readily pass through the sievelike filter into the nephron tubule Both lipid soluble and polar substances will pass through the glomerulus into the tubule filtrate Renal tubule The renal tubule is a long and convoluted structure that emerges from the glomerulus and can be divided See Answer
