Locomotion, gathers food, aids in respiration, and aids in excretion
The ampulla on a starfish is part of the water vascular system, and stores water and sends it to tiny tube feet on the ventral side of a starfish's arms. This process helps starfish move, as the water vascular system is the part of the starfish responsible for locomotion.
There is no ampulla of ductus deferens in pigs
what causes the ampulla of vater in the pancreas to be prominent
Echinoderms (which include starfish) have a water vascular system associated with movement in some species and feeding in others. Water is pumped around the system through the ring canal, lateral canals, radial canals, ampulla, podium and to the sucker feet. This water vascular system has a vacuum effect allowing the starfish to suction its many feet to the substrate and release them at its own will.
An ampulla of Vater is a swelling which marks the union of the pancreatic duct and the common bile duct.
The ampulla of an insect is the organ that holds sperm. It is used to transfer sperm during the act of reproduction.
An ampulla is either a two-handed Roman vessel, a vessel for holding consecrated wine or oil, or the dilated end of a duct.
An ampulla of Lorenzini is an electroreceptor found in many fish as well as sharks, forming a network of jelly-like canals.
It is located in the semicircular canals. Which have a swelling called an ampulla at their base-which contains crista ampullaris.
