the human is able regulate blood sugar levels within a fairly specific range, even high amounts of carbohydrates are consumed
Stells [14]

Question options:

1. Homeostasis

2. Digestion

3. Embryology

4. Cellular respiration

Answer:

<u>1. Homeostasis</u>

Explanation:

Sugar level in humans is regulated by "Insulin" and "glucagon" hormones that are secreted by the pancreas. Both hormones work in a balanced way to regulate the blood sugar level within a specific range if the sugar levels spike or drop.

Together,<u> </u><em><u>insulin and glucagon help maintain a state known as homeostasis</u></em><em>.</em> By definition, homeostasis is the maintenance of the internal environment of cell/body with respect to the external environment. Thus, homeostasis maintains a relatively stable state that persists despite changes in the world outside.<u> When blood sugar is too high, the pancreas secretes more insulin which acts to trigger breakdown of sugar thus reducing its level. By contrast, when blood sugar levels drop, the pancreas releases glucagon to allow conversion of macromolecules to simple sugars and raise its level.</u>
