Each nephron consists of two parts: a _____________________ where blood plasma is filtered, and a ___________________ into which the filtered fluid(glomerular filtrate) passes. (reference: textbook chapter 26 urinary system--section "parts of a nephron" and figure 26.5)

renal tubule; renal corpuscle

renal corpuscle; renal tubule

glomerulus; glomeruluar capsule

glomerular capsule; glomerulus

QUESTION 8

The two components of a renal corpuscle are the _________________ (capillary network) and the _________________ or (Bowman's capsule), which is a double walled epithelial cup. (reference: textbook chapter 26 urinary system--section "parts of a nephron" and figure 26.5)
