Question
All of the following statements pertaining to the physiology of stress are correct EXCEPT:
A The spleen discharges red and white blood cells, allowing the blood to transport more oxygen throughout the body, which primes the muscles, lungs, and brain for added demands.
B Adrenaline acts on alpha receptors of the blood vessels, which results in stimulation of the blood vessels.
C Stress hormones act indirectly on the lungs resulting in increased respiratory rate, which allows more oxygen to enter the lungs, which thereby allows more oxygen into the blood, which thereby allows more oxygen to enter various tissues throughout the body.
D The parasympathetic nervous system is responsible for activating the stress response, and the sympathetic nervous system is responsible for conserving energy and bringing you back to homeostasis.
Explanation / Answer
Pertaining to the physiology of stress all statement except option A that is the spleen discharge red and white blood cells, allowing the blood to transport more oxygen throughout the body, which primes the muscles, lungs, and brain for added demands. The spleen destroy the damaged red blood cells and remove it. It never discharge red blood cells. spleen produces white blood cells which has role in immunity and antibodies production. The metabolism of red blood cells occur in spleen. The haemoglobin is released in it and bile pigment and bile salts like bilirubin and biliverdin are formed in spleen. It form antibody in the white pulp from the circulating lymph.
All other options are correct in relation to physiology of stress.
