The exocrine pancreas is one of two compartments that include digestive-acting acinar cells and duct cells.They represent an extension of the intercalated duct into each pancreatic acinus. [1] These cells are commonly known as duct cells, and secrete an aqueous bicarbonate solution under stimulation by the hormone secretin. They also secrete ...
Acinar exocrine glands are found in many organs, including: the stomach [1] the sebaceous gland of the scalp; the salivary glands of the tongue [2] the liver; the lacrimal glands; the mammary glands; the pancreas [3] the bulbourethral (Cowper's) glands
Merocrine – the cells of the gland excrete their substances by exocytosis into a duct; for example, pancreatic acinar cells, eccrine sweat glands [dubious – discuss], salivary glands, goblet cells, intestinal glands, tear glands, etc. Apocrine – the apical portion of the cytoplasm in the cell membrane, which contains the excretion, buds off.
Cardiac physiology or heart function is the study of healthy, unimpaired function of the heart: involving blood flow; myocardium structure; the electrical conduction system of the heart; the cardiac cycle and cardiac output and how these interact and depend on one another.
A gland is a cell or an organ in an animal's body that produces and secretes different substances that the organism needs, either into the bloodstream or into a body cavity or outer surface. [1] A gland may also function to remove unwanted substances such as urine from the body. [2] There are two types of gland each with a different method of ...
It is synthesized in the acinar cells of the pancreas and stored inside membrane-bounded granules at the apex of the acinar cell. Release of the granules from the cell is stimulated by either a hormonal signal or a nerve impulse, and the granules spill into a duct leading into the duodenum .
It also plays a central role in building energy and proteins, and it can be found in your red blood cells, bone marrow, muscles and the brain. You may hear the terms " iron deficient " and "iron ...
Secretin primarily functions to neutralize the pH in the duodenum, allowing digestive enzymes from the pancreas (e.g., pancreatic amylase and pancreatic lipase) to function optimally. [24] Secretin targets the pancreas; pancreatic centroacinar cells have secretin receptors in their plasma membrane.
