You would expect blood levels of what to be high when the pH of stomach chyme is at its lowest?

Histamine levels would be high in the blood when the pH of stomach chyme is at its lowest. Histamine is released by enterochromaffin-like cells in response to low pH levels in the stomach, and it stimulates the release of gastric acid.


Release of the chemical histamine causes?

Release of histamine causes dilation of blood vessels, increased vascular permeability, and smooth muscle contraction. This can result in symptoms such as itching, redness, swelling, and bronchoconstriction depending on the location of release and the receptors it activates.


Function of the mast cells.?

Mast cells and basophils produce the histamine, which antihistamines block. The cytoplasm of a mast cell is filled with granules containing histamine and heparin. Histamine, released after injury or infection, stimulates local inflamation. People often take antihistamines to reduce cold symptoms. Basophils, blood cells that enter damaged tissues and enhance the inflammation process, also contain granules of histamine and haparin.


Do mast cells release histamine as a result of the allergen-antibody reaction?

Yes, mast cells release histamine in response to the allergen-antibody reaction. When an allergen binds to specific antibodies on the surface of mast cells, it triggers the release of histamine and other inflammatory mediators, leading to allergy symptoms.


How cold ice induce histamine release?

Ice can induce histamine release by causing the blood vessels in the skin to constrict, leading to a rapid rewarming process when the skin is rewarmed. This rapid rewarming can trigger the release of histamine from mast cells in the skin, leading to itching, redness, and swelling at the site of contact with ice.
