Question

the human body constantly senses, evaluates, and reacts to changes in environmental conditions to maintain a stable internal environment. this is homeostasis. after eating a meal, your blood glucose level increases. how does your body respond to an increase in blood sugars? a kidneys remove insulin b kidneys produce insulin c pancreas removes insulin d pancreas produces insulin

Explanation:

When blood glucose levels rise (e.g., after a meal), the pancreas, an organ in the endocrine system, plays a crucial role. The pancreas has cells called beta cells in the islets of Langerhans. These beta cells detect the increase in blood glucose. In response, they secrete insulin. Insulin is a hormone that helps cells (such as muscle, fat, and liver cells) take in glucose from the blood. This uptake of glucose by cells lowers the blood glucose level back to a normal range.

• Option A: The kidneys do not remove insulin. Their main functions related to blood include filtering waste products (like urea) and regulating water - salt balance.
• Option B: The kidneys do not produce insulin. Their role is more in excretory and osmoregulatory functions.
• Option C: The pancreas does not remove insulin; it produces and secretes insulin.

Answer:

D. pancreas produces insulin
