Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Insulin is secreted by which gland and what is its function?
A
ovaries; stimulates the development of female secondary sex characteristics and regulates the female reproductive system
B
pancreas; regulates the absorption of glucose into blood cells, decreasing blood glucose levels
C
testes; stimulates the development of male secondary sex characteristics and promotes sperm production
D
pituitary gland (anterior); stimulates milk production and breast development in females
Explanation: 

Detailed explanation-1: -Insulin is a peptide hormone secreted by the cells of the pancreatic islets of Langerhans and maintains normal blood glucose levels by facilitating cellular glucose uptake, regulating carbohydrate, lipid and protein metabolism and promoting cell division and growth through its mitogenic effects.

Detailed explanation-2: -Insulin allows the cells in the muscles, fat and liver to absorb glucose that is in the blood. The glucose serves as energy to these cells, or it can be converted into fat when needed. Insulin also affects other metabolic processes, such as the breakdown of fat or protein.

Detailed explanation-3: -Insulin is a polypeptide hormone mainly secreted by cells in the islets of Langerhans of the pancreas. The hormone potentially coordinates with glucagon to modulate blood glucose levels; insulin acts via an anabolic pathway, while glucagon performs catabolic functions.

Detailed explanation-4: -The pancreas produces the hormone insulin, which allows glucose from the bloodstream to enter the body’s cells where it is used for energy. In type 2 diabetes, too little insulin is produced, or the body cannot use insulin properly, or both. This results in a build-up of glucose in the blood.

Detailed explanation-5: -For instance, the pancreas secretes insulin, which allows the body to regulate levels of sugar in the blood.
