Secretion
29
Movement of small molecules and water from the blood in the glomerulus into the renal tubules.
Filtration
30
Recovery of most of the nutrients, water, and essential ions from the filtrate in the renal tubules, which are returned to the blood in the capillaries.
Resorption

Renal tubule
34
The cup-shaped, hollow structure that surrounds the glomerulus; also called a Bowman’s capsule.
Glomerular capsule
35
The filter that lies between the blood in the glomerulus and the capsular space.
Filtration membrane
36
A highly coiled tube that carries filtrate from the glomerular capsule to the nepron loop.
Proximal convoluted tubule
37
The U-shaped tube that connects the proximal and distal convoluted tubules.
Nephron loop (loop of Henle)
38
A highly coiled tube that carries filtrate from the nepron loop to a collecting duct.
Distal convoluted tubule
39
A tube that receives urine from several nephrons and runs straight through the cortex to the deeper medulla.
Collecting duct (tubule)
40
Structure composed of a portion of the afferent and efferent arteriole and terminal nepron loop that functions in regulation of blood pressure.
Juxtaglomerular apparatus
41
Region of the kidney where the renal corpuscle and convoluted tubules are located.
