Answer: Positive feedback loop
Explanation:
Even before the food reaches the stomach (before ingesting it), the glands of the stomach mucosa begin to release its gastric secretion. The main characteristic of this secretion is acidity, as measured by pH (one of the physiological variables).
This acidity is a result of the presence of hydrochloric acid, which is part of the secretion composition. In addition to it, water, pepsinogen (which will give rise to the enzyme pepsin) and the intrinsic factor. The acid has a function of the protection of the entire system by eliminating microorganisms. It is also responsible for the activation of pepsin (which only occurs with acid pH), the enzyme that digests proteins containing the amino acids leucine or phenylalanine or tryptophan or tyrosine.
The concept of Positive feedback loop states that the body tries to increase the value of a variable (acidity, in the case of pepsinogen) when it is below its optimal value (called a point adjustment) and decreases this value when it is above optimal.
Energy is released when a chemical bond forms between two identical atoms
Answer:
Proteins, Liver, Osmotic, Fluid, Into The Blood, Decrease.
Explanation:
Blood is considered a colloid because it contains proteins in the plasma.
Most of these are produced by the liver.
Collectively, these substances exert osmotic pressure and prevent the loss of fluid from the blood as it moves through the capillaries.
The pressure exerted by the plasma proteins is called colloid osmotic pressure.
This force is responsible for moving fluids into the blood and preventing excess fluid loss between blood capillaries and the interstitial fluid.
If plasma protein levels decrease, colloid osmotic pressure will decrease.
