The pancreas is an organ of the digestive system and endocrine system of vertebrates. In humans, it is located in the abdomen behind the stomach and functions as a gland. The pancreas is a mixed or heterocrine gland, i.e., it has both an endocrine and a digestive exocrine function. [2] 99% of the pancreas is exocrine and 1% is endocrine.
Endocrine function: This involves the secretion of hormones directly into the bloodstream. Pancreas produces hormones such as insulin and glucagon, which help regulate blood sugar level. Insulin is released when blood sugar levels are high, and it promotes the uptake of glucose by cells, reducing blood sugar (hypoglycemia).
The pancreas produces and releases important digestive enzymes in the pancreatic juice that it delivers to the duodenum. [24] The pancreas lies below and at the back of the stomach. It connects to the duodenum via the pancreatic duct which it joins near to the bile duct's connection where both the bile and pancreatic juice can act on the chyme ...
The hypothalamus, pancreas, and thymus also function as endocrine glands, among other functions. (The hypothalamus and pituitary glands are organs of the neuroendocrine system . One of the most important functions of the hypothalamus—it is located in the brain adjacent to the pituitary gland—is to link the endocrine system to the nervous ...
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 ...
While ductal cells are a minor type of cell in the adult pancreas, they have a critical function besides making the network that transfers enzymes from acini to the digestive tract. The primary function of pancreas ductal cells is to secrete a bicarbonate-rich, isotonic fluid. This fluid washes away the inactive form of digestive enzymes in the ...
The main functions of the urinary system and its components are to: Regulate blood volume and composition (e.g. sodium, potassium and calcium) Regulate blood pressure. Regulate pH homeostasis of the blood. Contributes to the production of red blood cells by the kidney. Helps synthesize calcitriol (the active form of Vitamin D).
Pancreatic polypeptide cells (PP cells), or formerly as gamma cells (γ-cells), or F cells, are cells in the pancreatic islets (Islets of Langerhans) of the pancreas. Their main role is to help synthesize and regulate the release of pancreatic polypeptide (PP) , after which they have been named.
