Insulin and Glucagon, synthesized by the islets of Langerhans in the pancreas, reach their target cells via

The correct answer is Blood

Explanation:

• Insulin and glucagon are hormones produced by the islets of Langerhans in the pancreas, which play crucial roles in maintaining blood glucose levels.
• The endocrine function of the pancreas involves the secretion of these hormones directly into the bloodstream, allowing them to reach their target cells in various parts of the body.
• Insulin and glucagon are secreted by the endocrine cells of the pancreas (beta cells for insulin and alpha cells for glucagon) into the blood.
• The blood serves as the transport medium for these hormones, carrying them to target tissues such as the liver, muscles, and fat cells.
• The bloodstream ensures rapid and efficient delivery, enabling the hormones to regulate blood sugar levels effectively.
