The location of kidneys in humans can be best described as:
1. | between last thoracic and third lumbar vertebra close to dorsal inner wall of abdominal cavity |
2. | between last thoracic and third lumbar vertebra close to ventral inner wall of abdominal cavity |
3. | between 10th thoracic and third lumbar vertebra close to dorsal inner wall of abdominal cavity |
4. | between 10th thoracic and third lumbar vertebra close to ventral inner wall of abdominal cavity |
I: | The right kidney is located slightly lower than the left kidney. |
II: | The average weight of human kidney varies between 120 g and 170 g. |
Recessed central fissure on the medial surface of the kidney where its vessels, nerves and ureter pass is called as:
1. | hilum | 2. | renal sinus |
3. | renal calyces | 4. | adrenal glands |
Ureters:
1. | transport urine to the urethra |
2. | transport urine from the renal pelvis to the urinary bladder |
3. | collect urine directly from collecting ducts |
4. | are lined with squamous epithelium |
In the male, urethra serves to:
1. transport urine from kidney to bladder
2. transport sperms to ejaculatory ducts
3. store urine and sperms
4. discharge semen and urine
Urine from the major calyces in the kidney is collected by:
1. | minor calyces | 2. | renal pelvis |
3. | ureters | 4. | renal papillae |
1. | Renal hilum | the entry and exit site for structures servicing the kidneys: vessels, nerves, lymphatics, and ureters. |
2. | Columns of Bertini | Extension of renal medulla into renal cortex |
3. | Renal pelvis | The funnel-like dilated part of the ureter in the kidney |
4. | Renal capsule | A tough fibrous layer surrounding the kidney |
The renal cortex:
1. is in contact with the outer capsule
2. is divided into eight to fifteen conical renal pyramids
3. drains into the minor calyces
4. has long loop of Henle of juxtamedullay nephrons
10 to 15 distinct conical or triangular structures in the human kidney are seen in renal ______ and are known as renal ____________.
1. | pelvis; calyces | 2. | medulla; pyramids |
3. | cortex; columns of Bertini | 4. | cortex; lobes |
