What else can I help you with?
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.
What cells release histamine during allergic responses?
Basophil
The pressure of massage techniques stimulates the release of these hormones to vasodilate the blood vessels?

Is gastrin an hormone?

Which leukocytes release histamine during the inflammatory response?
Actualy white blood cells release histamine.
What is the antonym for the word antihistamine?
Anti-histamine means a substance which inhibits the release of histamine. Its opposite would be something that promotes the release of histamine. There is no standard word for such a material but one can use prohistamine for it.
What release histamine and is the least common granulocytes?
The basophil releases histamine and is the least common granulocyte.
What is a chemical that stimulates the dilation of capillaries?
There are many vasodilators. These include histamines, nitric oxide, CO2, H+, K+, adenosine and epinephrine.
What granulocyte produces histamine?
Basophils are granulocytes that produce and release histamine. Histamine is an inflammatory mediator involved in various immune responses, such as allergic reactions and defense against pathogens.
