lab 13: nephrons

glomerulus

has the afferent and efferent arterioles going into its capillary network

tubules

• proximal convoluted tubule

• descending and ascending limb of Loop of Henle

• Distal convoluted tubule

• collecting tubule

  • collecting duct

afferent arteriole

delivers blood to the glomerulus

renal corpuscle/bowman’s capsule

• spherical structure

• has the glomerulus and the glomerular capsule

• composed to the glomerulus and glomerular capsulebu

  • site of filtration

glomerular capsule

• cup-shaped chamber

• receives filtered fluid from glomerulus

• delivers filtrate to the proximal convoluted tubule

proximal convoluted tubule

• highly folded and twisting tubule

  • receives filtrate from glomerular capsule

peritubular capillaries

capillaries surrounding distal and proximal convoluted tubules

distal convoluted tubule

• farther from the glomerulus

• highly folded and twisting tubule

• receives filtrate from nephron loop

nephron loop/loop of henle

• 2 long, straight tubules connected by hairpin turn

  • includes ascending and descending limb

collecting duct

• recieves filtrate from distal convoluted tubule

• becomes part of renal pyramid

  • delivers filtrate, now urine, to renal papilla

efferent arteriole

conducts blood from glomerulus to peritubular capillaries (blood vessel)
