FAQs on Pancreas: Role & Anatomy Video Lecture - Biology for Grade 11
| 1. What is the role of the pancreas in the body? |  |
Ans. The pancreas plays a crucial role in the digestive and endocrine systems. It produces digestive enzymes that help break down carbohydrates, proteins, and fats in the small intestine. Additionally, it produces insulin and glucagon, which regulate blood sugar levels.
| 2. How is the pancreas anatomically structured? | |
Ans. The pancreas is an elongated gland located behind the stomach in the upper abdomen. It has a head, body, and tail. The head is positioned on the right side of the abdomen and is connected to the duodenum (part of the small intestine). The body extends horizontally across the abdomen, and the tail tapers toward the left side.
| 3. What are the common diseases associated with the pancreas? | |
Ans. Some common diseases related to the pancreas include pancreatitis (inflammation of the pancreas), pancreatic cancer, and diabetes. Pancreatitis can be caused by excessive alcohol consumption or gallstones. Pancreatic cancer is a highly aggressive form of cancer that often only shows symptoms in the advanced stages. Diabetes can occur when the pancreas does not produce enough insulin or the body becomes resistant to its effects.
| 4. How can pancreatitis be diagnosed? | |
Ans. Pancreatitis can be diagnosed through a combination of medical history, physical examination, blood tests, and imaging studies. Blood tests may show elevated levels of pancreatic enzymes, such as lipase and amylase. Imaging techniques like ultrasound, CT scan, or MRI can help visualize the pancreas for any signs of inflammation or damage.
| 5. What are the functions of insulin and glucagon produced by the pancreas? | |
Ans. Insulin and glucagon are hormones produced by the pancreas that work together to regulate blood sugar levels. Insulin helps lower blood sugar levels by facilitating the uptake of glucose from the bloodstream into cells. It also promotes the storage of excess glucose as glycogen in the liver. On the other hand, glucagon raises blood sugar levels by stimulating the liver to break down glycogen into glucose and release it into the bloodstream. These hormones help maintain a stable blood sugar balance in the body.
