renal calyx. the first unit in the system of ducts in the kidney carrying urine from the renal pyramid of the medulla to the renal pelvis for excretion through the ureters.
What are the functions of the minor calyx?
A minor calyx drains one renal papilla, which empties into a single minor calyx through a projection into its lumen. The renal papillae represent the tips of renal pyramids and the location where urine leaves the filtering portion of the kidney tissue to enter the collecting area. Peristalsis , originating in the smooth muscle of the calyces and initiated by pacemaker cells, enables urine to be propelled through both the renal pelvis and the ureters to the bladder.
What is the function of the calyx in plants?
In many Fabaceae flowers, a calyx tube surrounds the petals. A sepal (/ˈsɛpəl/ or /ˈsiːpəl/) is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom.
