Red blood cells: Red blood cells (RBCs, also called erythrocytes; say: ih-RITH-ruh-sytes) are shaped like slightly indented, flattened disks. RBCs contain hemoglobin (say: HEE-muh-glow-bin), a protein that carries oxygen. Blood gets its bright red color when hemoglobin picks up oxygen in the lungs.

Why do the levels of GH-RH and CRH rise during the resistance phase of the general adaptation syndrome?
Alenkinab [10]

Answer:

During the resistance phase of the general adaptation syndrome, the human body undergoes a process of adaptation or tolerance to stress, which requires an increase in levels of growth hormone (GH) and cortisol, so it is observed rise the levels of GHRH and CRH.

Explanation:

General adaptive syndrome is a product of the stress to which an individual is subjected, causing a number of symptoms reflecting the loss of normal body balance, symptoms that can be both physical and psychological. This syndrome has three phases:

  • <em>Alarm phase. </em>
  • <em>Resistance phase. </em>
  • <em>Exhaustion phase. </em>

The second phase, resistance, is due to an <u>adaptation or tolerance when the stressful stimulus is maintained</u>. At this stage, an increase in blood levels of growth hormone and cortisol -which contribute to the stress tolerance process- is usually observed, increasing the bioavailability of blood glucose and endogenous steroids.

Both GHRH (somatocrin) and CRH (corticotropin-releasing hormone) are produced by the hypothalamus and activate the release of GH and adrenocorticopotrotrope hormone (CRH) by the pituitary gland, producing:

  1. <em>Increased levels of circulating growth hormone, necessary to regulate metabolism, and increase the amount of blood glucose. </em>
  2. <em>Increased levels of cortisol, from the adrenal glands, in response to stress.  </em>

In the resistance phase of general adaptative syndrome, GHRH and CRH levels increase to regulate adaptive changes that occur in the body of the individual who has it.
