What is an interlobular duct?
The ducts pass from the lobules into the connective tissue septa where they join one to another. In this image are several secretory ducts (A) together with an artery (B) and vein (C) in a connective tissue septum located between two lobules. These particular secretory ducts are referred to as interlobular ducts.
Where are Interlobular ducts found?
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 do intercalated ducts secrete?
The epithelial cells of the intercalated ducts can secrete water and bicarbonate ions, although in the rat this role is largely performed by the epithelium of the interlobular ducts.
Why are striated ducts striated?
The striated appearance is due to basal accumulation of vertically oriented mitochondria (Tandler, 1993a,b). Several acini compose a lobule, where their respective intercalated and striated ducts drain into an intralobular duct. Lobules of the gland are separated by connective tissue.
What is a interlobar artery?
The interlobar arteries are vessels of the renal circulation which supply the renal lobes. The interlobar arteries branch from the lobar arteries which branch from the segmental arteries, from the renal artery.
What are intercalated ducts and striated ducts?
The intercalated duct, also called intercalary duct (ducts of Boll), is the portion of an exocrine gland leading directly from the acinus to a striated duct. The intercalated duct forms part of the intralobular duct.
Is striated duct Interlobular?
The striated ducts lead into interlobular (excretory) ducts, lined with a tall columnar epithelium. The glands are divided into lobules by connective tissue septa. Each lobule contains numerous secretory units, or acini. Images A,B, and C are of three different salivary glands.
What is intercalated duct?
What are primary ducts?
Primary or main ducts, arising from the stomach wall, have a ciliated part and a smooth part, while secondary ones are not ciliated and have a shorter diameter.
Where is the Interlobar artery?
the kidney
structure of the kidney Many arteries, called interlobular arteries, branch off from the arcuate arteries and radiate out through the cortex to end in networks of capillaries in the region just inside the capsule.
What is the function of interlobar arteries and veins?
Interlobular veins run alongside the interlobular arteries and collect venous blood from the capillary plexus of the cortex. As noted earlier, the venous return from the medulla runs to the arcuate veins. Arcuate veins deliver blood to the interlobar veins.
What are interlobar arteries?
The interlobar arteries are vessels of the renal circulation which supply the renal lobes. The interlobar arteries branch from the lobar arteries which branch from the segmental arteries, from the renal artery. They give rise to arcuate arteries.
Is duct of Wirsung and Hepatopancreatic duct same?
…the main pancreatic duct (duct of Wirsung) at a slightly dilated area called the hepatopancreatic ampulla (ampulla of Vater), which lies in the wall of the inner curve of the descending duodenum, and terminates in the lumen of the duodenum at a 2- to 3-cm elevation called the duodenal…
What are glandular ducts?
Glandular epithelium is formed during fetal life by the development of epithelial cells into the connective tissue underlying the epithelium. Initially, all glands are connected to the surface epithelium by a channel called a duct.
What does the interlobar artery do?
Interlobular arteries arise from the arcuate arteries and ascend into the cortex, where they divide into afferent arterioles that supply blood to the glomerular capillaries. After traversing the renal corpuscle, the glomerular capillaries reform into a second arteriolar network, the efferent arterioles.
What is interlobar?
Medical Definition of interlobar : situated between the lobes of an organ or structure.
