The pancreas
The part of the pancreas which secretes insulin is called the Isles of Langerhans.
No, the pineal gland secretes melatonin. The pancreas secretes insulin.
Insulin
The pancreas secretes insulin, which is a hormone that helps regulate blood sugar levels in the body. Insulin plays a crucial role in the absorption of glucose into cells for energy production.
The pancreas is the structure that secretes insulin, a hormone critical for regulating blood sugar levels. Specifically, insulin is produced by the beta cells located in the islets of Langerhans within the pancreas. When blood sugar levels rise after eating, insulin helps facilitate the uptake of glucose by cells, thereby lowering blood sugar levels.
Several hormones are secreted by the pancreas. They include insulin, glucagon, somatostatin, and pancreatic peptide.
I think alpha cells in the pancreas secretes hormone insulin. Beta cells of pancreas secretes hormone glucagon. Both insulin and glucagon have antagonist effect of one another.
The ovary secretes a hormone called estradiol, which promotes the maturation of eggs (gametes) in females.
The letter that typically indicates a structure that secretes a hormone not involved in the production or delivery of gametes is "A," referring to the pancreas. The pancreas secretes hormones such as insulin and glucagon, which regulate blood sugar levels, and these functions are unrelated to gamete production or delivery.
The pancreas secretes insulin and glucagon, which are hormones that help regulate blood sugar levels in the body. Insulin lowers blood sugar levels, while glucagon helps raise them when they are too low.
A hormone is a chemical, not a cell. They thyroid gland that secretes the thyroid hormone (which is called thyroxin) is composed of cells.
It is both an endocrine (gland that secretes hormones; insulin, glucagon, and somatostatin, among others...) and a digestive gland (breaks down sugars). Search Wikipedia for Pancreas and it'll give you the "details".
