Which feedback mechanism is used to regulate blood glucose?
ASHA 777 [7]

<span><span>B. a negative feedback loop because the blood glucose level was returned to the set point, not amplified

</span>The glands which get involved are the pancreas and adrenal glands.</span><span> During increase in blood sugar, the pancreas secretes insulin, a hormone produced by the beta cells of the pancreas. Insulin causes red blood cells, muscle cells and fat cell to absorb sugar from the blood.</span><span>During decrease of blood sugar, the pancreas secretes  glucagon, a hormone produced by the alpha cells of the pancreas. Glucagon causes the liver to release the glucose stored in its cells.</span><span>The Adrenal gland secretes cortisol during times of low blood sugar levels.  Cortisol promotes the use of fatty acids to provide energy for working muscles, rather than using glucose.</span>

During inflation, air moves in the lungs when the air pressure within the alveolar spaces falls below the atmospheric pressure

The forces that normally cause changes in volume of the chest and lungs arises not only from muscle contraction but from the elastic properties of both the lung and the chest

The force required to maintain inflation of the lung and to cause airflow is provided by the chest and diaphragm (the muscular partition between chest and abdomen), which are in turn stretched inward by the pull of the lungs

Hence during lung inflation, the lungs cling to the internal surface of the chest wall as it expands
