Is the pancreas a compound acinar gland?
The pancreas is a compound, acinar, serous, exocrine gland with islets of endocrine cells. Most of this view appears packed with secretory acini. Most of these are cut in random planes and look like solid lumps, made of cells having various sizes and shapes.
What is a compound Tubuloacinar gland?
Explanation: Compound tubular glands are glands that have branched ducts. So the duct of a compound gland branches repeatedly. This in contrast to simple glands that consist of a single secretory passage / an unbranched common duct.
Is pancreas a Tubuloacinar?
The exocrine component of the pancreas makes up about 98% of the pancreatic tissue. It is comprised of densely packed serous acinar (tubuloacinar) glands.
What do compound tubular glands secrete?
Compound Tubular Gland Salivary glands are exocrine glands with branching ducts. The secretory components will release to the surface to provide salivation and mucus to assist with mastication and digestion.
Why pancreas is called a compound gland?
The pancreas is thus a compound gland in the sense that it is composed of both exocrine and endocrine tissues. The exocrine function of the pancreas involves the synthesis and secretion of pancreatic juices.
What compounds does the pancreas secrete?
During digestion, your pancreas makes pancreatic juices called enzymes. These enzymes break down sugars, fats, and starches. Your pancreas also helps your digestive system by making hormones. These are chemical messengers that travel through your blood.
Where are compound Tubuloacinar glands found?
Compound tubular glands have a compound duct system with branching networks of tubular-shaped glands. These types of glands are found in the kidneys, the seminiferous tubules of the testes, and the mucous glands in the mouth.
Is the pancreas a compound tubuloalveolar?
Compound tubular glands where the duct is branched and the secretory parts are tubular (e.g., liver). glands). (e.g., salivary glands and pancreas).
Why the pancreas is considered both an exocrine and an endocrine gland?
Pancreas is an exocrine gland as it has a duct to store pancreatic juice secreted by the pancreas and use it whenever required. It is considered as a endocrine gland as it does not have a duct to store the hormones insulin and glucagon which are directly supplied to the blood stream.
What is the functional unit of pancreas?
The functional unit of the exocrine pancreas is composed of an acinus and its draining ductule (Figure 3). The ductal system extends from the lumen of the acinus to the duodenum. A ductule from the acinus drains into interlobular (intercalated) ducts, which in turn drain into the main pancreatic ductal system.
What is the difference between simple and compound gland?

What is the difference between branched and compound exocrine glands?
Exocrine Glands Simple glands – these have a single, unbranched duct. Examples include sebaceous glands, intestinal crypts and uterine glands. Compound glands – these have multiple, branched ducts. Examples include the salivary glands and the pancreas.
What do you mean by compound gland?
A compound gland has a branching duct. Salivary glands and pancreas are familiar examples. Compound glands are typically fairly bulky and contain very many individual secretory units (acini or tubules).
What is tubuloalveolar gland?
[ tōō′byə-lō-ăl-vē′ə-lər ] n. A gland whose secretory portions end in tubular and alveolar configurations.
What is the function of the pancreas in the endocrine system?
The pancreas performs two main functions: Exocrine function: Produces substances (enzymes) that help with digestion. Endocrine function: Sends out hormones that control the amount of sugar in your bloodstream.
Why is pancreas called as exocrine gland?
Pancreas is considered as an exocrine gland because it has a duct to store pancreatic juice secreted by the pancreas and use it whenever required.
Why is pancreas called mixed gland?
Since the pancreas has both endocrine and exocrine functions, it is therefore a mixed gland. Its endocrine secretions are the hormones insulin and glucagon.
Which is the exocrine gland of pancreas?
The pancreas is divided into an exocrine portion (acinar and duct tissue) and an endocrine portion (islets of Langerhans). The exocrine portion, comprising 85% of the mass of the pancreas, secretes digestive enzymes, (more…)
Which of the following is a compound gland?
Why pancreas are called compound gland and what are compound glands?
What is the structure and function of the pancreas?
pancreas, compound gland that discharges digestive enzymes into the gut and secretes the hormones insulin and glucagon, vital in carbohydrate (sugar) metabolism, into the bloodstream. In humans the pancreas weighs approximately 80 grams (about 3 ounces) and is shaped like a pear.
What is the structure of the exocrine pancreas?
The exocrine pancreas is a compound tubulo-acinar gland composed of serous secretory cells. The duct system branches extensively, with each branch terminating in a luminal space bound by the secretory acinar cells.
How does the pancreas regulate blood sugar levels?
As part of the endocrine system, the pancreas secretes two main hormones that are vital to regulating your glucose (also known as blood sugar) level: Insulin.
What does the pancreas look like on histology slides?
On histology slides, the pancreas can look very similar to other glandular tissue, such as the parotid gland. However, one unique feature of the pancreas that differentiates it from other glands are the pancreatic islets, which are clearly demarcated from the pancreatic acini.
