Juxtamedullary nephrons:
1. are more common than cortical nephrons
2. do not have a well developed vasa recta associated with them
3. play a very important role in concentration of urine
4. produce angiotensinogen
Beginning from the collecting duct, arrange the following structures in the correct sequence in which urine passes to the external environment: (A) ureter, (B) renal pelvis, (C) calyx, (D) urinary bladder, (E) urethra.
1. A, B, C, D, E | 2. C, D, A, E, B |
3. C, B, A, D, E | 4. B, D, A, C, E |
A capillary network around the renal tubule is formed by:
1. Afferent arteriole | 2. Efferent arteriole |
3. Vasa recta | 4. Arcuate artery |
A series of straight capillaries in the medulla that lie parallel to the loop of Henle are called:
1. | arcuate arteries | 2. | efferent arterioles |
3. | afferent arterioles | 4. | vasa recta |
The proximal convoluted tubule of the nephron is lined by:
1. simple ciliated cuboidal epithelium
2. simple ciliated columnar epithelium
3. compound cuboidal brush bordered epithelium
4. simple cuboidal brush bordered epithelium
The part of the nephron that is least permeable to water is the:
1. ascending limb of the loop of Henle
2. descending limb of the loop of Henle
3. collecting duct
4. proximal convoluted tubule
The part of the nephron where both hydrogen and potassium ions are secreted into the tubular fluid is the
1. Malpighian body | 2. proximal convoluted tubule |
3. loop of Henle | 4. distal convoluted tubule |
