What surrounds the interlobular duct?
What surrounds the interlobular duct?
The intralobular ducts fuse to form the interlobular ducts, which are found between lobules, within the connective tissue septa and surrounded by a rim of collagen (Figure 10).
What are the excretory ducts of pancreas?
The pancreatic duct, or duct of Wirsung (also, the major pancreatic duct due to the existence of an accessory pancreatic duct), is a duct joining the pancreas to the common bile duct. This supplies it with pancreatic juice from the exocrine pancreas, which aids in digestion.
What is the difference between intercalated duct and striated duct?
Intercalated ducts merge to form striated ducts, whose epithelia are composed of simple columnar or stratified columnar epithelia (Tandler, 1993b). The striated appearance is due to basal accumulation of vertically oriented mitochondria (Tandler, 1993a,b).
What is interlobular duct?
Interlobular ducts are found between lobules, within the connective tissue septae. They vary considerably in size. The smaller forms have a cuboidal epithelium, while a columnar epithelium lines the larger ducts. Intralobular ducts transmit secretions from intralobular ducts to the major pancreatic duct.
What is the interlobular duct used for?
The interlobular ducts empty into a single pancreatic duct that joins with the duodenum. The epithelium of the intercalated ducts secretes fluid with a high concentration of sodium bicarbonate that serves to buffer acid arriving in the duodenum from the stomach.
What are the three types of saliva?
Salivary Glands and Saliva
- parotid glands produce a serous, watery secretion.
- submaxillary (mandibular) glands produce a mixed serous and mucous secretion.
- sublingual glands secrete a saliva that is predominantly mucous in character.
Does pancreas have Interlobular ducts?
Histology. The pancreas has a lobulated structure and there are intralobular ducts penetrating the secretory acini, which are flask-shaped structures consisting of typical zymogenic cells. The larger interlobular ducts contain some nonstriated smooth muscle.
Why it is called striated duct?
Striated ducts assume their typical histological striated appearance and derive their name from numerous folds and invaginations of the apical plasma membrane, which is rich in various ion pumps.
What is the function of ducts?
Ducts are conduits or passages used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air. The needed airflows include, for example, supply air, return air, and exhaust air. Ducts commonly also deliver ventilation air as part of the supply air.
What does duct mean?
Definition of duct (Entry 1 of 2) 1 : a bodily tube or vessel especially when carrying the secretion of a gland. 2a : a pipe, tube, or channel that conveys a substance. b : a pipe or tubular runway for carrying an electric power line, telephone cables, or other conductors.
