What are the Cuplike structures found in the renal pelvis called?
The periphery of the renal pelvis is interrupted by cuplike projections called calyces. A minor calyx surrounds the renal papillae of each pyramid and collects urine from that pyramid.
What is the Cuplike collecting region of the renal pelvis?
Urinary System
| Question | Answer |
|---|---|

| tube for injecting or removing fluids | catheter |
| outer region of an organ | cortex |
| nigrogenous waste excreted in urine | creatinine |
What are the parts of the renal pelvis?
The renal pelvis contains the hilium. The hilum is the concave part of the bean-shape where blood vessels and nerves enter and exit the kidney; it is also the point of exit for the ureters—the urine-bearing tubes that exit the kidney and empty into the urinary bladder.
What does renal pelvis mean?
Listen to pronunciation. (REE-nul PEL-vus) The area at the center of the kidney. Urine collects here and is funneled into the ureter, the tube that connects the kidney to the bladder.
What is the medical term for renal pelvis?
The words infundibulum and choana are other words for funnel-shaped cavities (which medical English got from the Latin and Greek words for “funnel”, respectively), and the renal pelvis is sometimes called the renal infundibulum.
What is the correct order of the renal tubules?
After leaving the renal corpuscle, the filtrate passes through the renal tubule in the following order, as shown in the diagram: proximal convoluted tubule (red: found in the renal cortex) loop of Henle (blue: mostly in the medulla) distal convoluted tubule (purple: found in the renal cortex)
What is the combining form for the renal pelvis?
The renal pelvis is occasionally called the pyelum (from Greek πύελος pýelos, “trough”, ‘anything hollow’), and the combining form pyelo- denotes the renal pelvis (pyelo- is not to be confused with pyo-).
What are the functions of the renal pelvis?
The kidney pelvis acts like a funnel, collecting the urine produced in the kidney and leading to a central “stem,” the ureter.
How is the renal pelvis like the ureter?
Renal pelvis. The large end of the pelvis has roughly cuplike extensions, called calyces, within the kidney—these are cavities in which urine collects before it flows on into the urinary bladder. Like the ureter, the renal pelvis is lined with a moist mucous-membrane layer that is only a few cells thick; the membrane is attached to…
Is the lining of the pelvis impermeable to urine?
The lining of the pelvis and of the ureter is impermeable to the normal substances found in urine; thus, the walls of these structures do not absorb fluids. The Editors of Encyclopaedia Britannica This article was most recently revised and updated by Adam Augustyn, Managing Editor, Reference Content.
How are muscle fibres arranged in the renal pelvis?
Renal pelvis. The mucous membrane of the pelvis is somewhat folded so that there is some room for tissue expansion when urine distends the pelvis. The muscle fibres are arranged in a longitudinal and a circular layer. Contractions of the muscle layers occur in periodic waves known as peristaltic movements.
What does it mean to have an enlarged pelvis?
See Article History. Renal pelvis, enlarged upper end of the ureter, the tube through which urine flows from the kidney to the urinary bladder.
