Biology Adolescence Part 12 (Pancreas & its hormones Insulin, Glucagon) Class 8 VIII

TL;DR

The pancreas acts as both an endocrine and exocrine gland, with the endocrine part called the islet of Langerhans. It releases hormones like insulin and glucagon to maintain blood glucose levels.

Key Insights

• 🧑‍🏭 The pancreas acts as both an endocrine and exocrine gland.
• 🤙 The endocrine part of the pancreas is called the islet of Langerhans.
• ❓ The islet of Langerhans is responsible for secreting hormones like insulin and glucagon.
• 😘 Insulin helps lower blood glucose levels by converting extra glucose into glycogen.
• 🏪 Glucagon increases blood glucose levels by converting stored glycogen back into glucose.
• 💦 Insulin and glucagon work together to maintain blood glucose homeostasis.
• 🥺 Disorders of insulin and glucagon can lead to diabetes mellitus and abnormal blood glucose levels.

Questions & Answers

Q: What is the function of the endocrine part of the pancreas?

The endocrine part of the pancreas, called the islet of Langerhans, releases hormones to maintain blood glucose levels.

Q: What is the significance of the islet of Langerhans?

The islet of Langerhans is responsible for secreting hormones like insulin and glucagon, which help regulate blood glucose levels.

Q: What is the role of insulin in the body?

Insulin is a hormone secreted by beta cells of the pancreas and helps lower blood glucose levels. It converts extra glucose into glycogen for storage in the body.

Q: What is the function of glucagon?

Glucagon, secreted by alpha cells of the pancreas, increases blood glucose levels. It converts stored glycogen back into glucose in emergency situations.

Summary & Key Takeaways

• The pancreas acts as both an endocrine and exocrine gland, with the endocrine part called the islet of Langerhans.

• The islet of Langerhans is a cluster of cells that release hormones to maintain blood glucose levels.

• Insulin and glucagon are two important hormones secreted by the islet of Langerhans to regulate blood glucose levels.
