Related to homeostatic control of a variable, which of the following is/are example(s) of a feedforward mechanism? Increased plasma glucose concentration stimulates insulin secretion, which stimulates glucose uptake into cells, which decreases plasma glucose concentration Stretch of the stomach by swallowing the first few bites of food stimulates increased parasympathetic activity to the pancreas, which increases insulin secretion, which stimulates increased glucose uptake into cells, although no glucose has been absorbed and plasma glucose concentration is unchanged as ye Low plasma glucose concentration stimulates glucagon secretion, which stimulat the liver to produce and release glucose, which increases plasma glucose concentration Hemoglobin concentration in blood at sea-level is normally about 14 g/dL. Hemoglobin in the blood binds oxygen and allows adequate oxygen delivery to tissues. At high altitude, there is less oxygen that can be inspired and so total oxygen carried in the blood decreases upon ascent in altitude. It is seen that immediately upon arrival at high altitude, hemoglobin levels are unchanged, but after a week at high altitude, hemoglobin levels increase and the oxygen carrying capacity of blood increases. Additionally, 1 week after return to sea-level, hemoglobin levels are back to the typical value of 14g/dL
