Question

1. circle the term that does not belong in each of the following groupings. then, fill in the answer blanks with the correct group name. 1. intraperitoneal dorsal body wall retroperitoneal superior lumbar region group: ____ 2. calyx ureter urethra renal pelvis group: __ 3. secretion reabsorption glomerulus low - pressure vessels group: __ 4. renin distal tubule glomerulus afferent arteriole group: __ 5. glomerulus peritubular capillaries efferent arteriole collecting duct group: __ 6. cortical nephrons cortex/medulla junction long nephron loops group: __ 7. renal corpuscle proximal convoluted tubule distal convoluted tubule collecting duct group: __ 8. glomerular capsule podocytes nephron loop glomerulus group: ____

Explanation:

1. Group 1: Intraperitoneal, retroperitoneal, and superior lumbar region describe abdominal cavity/space locations; dorsal body wall is a structural tissue layer.
2. Group 2: Calyx, renal pelvis, and ureter are upper urinary tract structures; urethra is the lower urinary tract exit.
3. Group 3: Secretion, reabsorption, and low-pressure vessels relate to nephron fluid processing; glomerulus is a filtration structure.
4. Group 4: Distal tubule, glomerulus, and afferent arteriole are nephron structural parts; renin is an enzyme/hormone.
5. Group 5: Glomerulus, peritubular capillaries, and efferent arteriole are renal vascular structures; collecting duct is a tubular structure.
6. Group 6: Cortex/medulla junction and long nephron loops are features of juxtamedullary nephrons; cortical nephrons are a separate nephron type.
7. Group 7: Renal corpuscle, proximal convoluted tubule, and distal convoluted tubule are parts of a single nephron; collecting duct serves multiple nephrons.
8. Group 8: Glomerular capsule, podocytes, and glomerulus form the renal corpuscle; nephron loop is a separate nephron segment.

Answer:

1. Outlier: Superior lumbar region; Group: Abdominal cavity/space locations
2. Outlier: Urethra; Group: Upper urinary tract structures
3. Outlier: Glomerulus; Group: Nephron fluid processing functions/structures
4. Outlier: Renin; Group: Nephron structural components
5. Outlier: Collecting duct; Group: Renal vascular structures
6. Outlier: Cortical nephrons; Group: Juxtamedullary nephron features
7. Outlier: Collecting duct; Group: Individual nephron segments
8. Outlier: Nephron loop; Group: Renal corpuscle components
