Answer

✨ Direction: Show how the nervous system coordinates and regulates feedback mechanism to maintain homeostasis by creating a graphic organizer. Select one from the following options. ✨

1. How do the nervous and endocrine systems respond to an increase in environmental temperature to achieve homeostasis. ?

✨ The nervous system controls and regulates the parts of the body to maintain homeostasis. A deviation from the normal set point of environmental temperature acts as a stimulus to a receptor. ... Hormones regulate the activity of the body cells so the endocrine system plays a significant role in homeostasis. ✨

2. Suppose a boy skipped his lunch for the day. How will the hormones (glucagon) from his pancreas help his body to cope when his blood sugar level drops below normal?

✨ Glucagon's role in the body is to prevent blood glucose levels dropping too low. To do this, it acts on the liver in several ways: It stimulates the conversion of stored glycogen (stored in the liver) to glucose, which can be released into the bloodstream. This process is called glycogenolysis. ✨

3.Suppose a girl ate too many sweets such as candies and chocolates. How will the hormones (insulin) from her pancreas help her body cope with a possible blood sugar level rise above normal?

✨ That’s the whole point of insulin- to keep blood sugar within stable limits.

When we eat, and glucose is absorbed into the blood, the blood level rises. As it rises, the brain triggers the pancreas. The pancreas makes and releases the insulin into the blood. As long as blood sugar is above a certain level, the insulin will be secreted to bring it to normal. The insulin works nearly instantly to cause cells to take in the glucose for energy. There is an acceptable variance in blood sugar, one when the person is fasting (the lowest the body allows the blood sugar to go) and postprandial (after a meal) which is the highest the body allows it to go.

If the body cannot control the rise in blood sugar, that’s called Diabetes. ✨
