The white blood cells that release the chemical histamine are called mast cells. These cells play a crucial role in the immune response, particularly during allergic reactions and inflammation. When activated, mast cells release histamine, which contributes to increased blood flow and the dilation of blood vessels, leading to symptoms such as swelling, redness, and itching.
What else can I help you with?
What type of white blood cell releases the chemical histamine?
Basophil granulocytes (usually called basophils) are the type of white blood cell that release histamine. This is an important part of inflammation.
What Chemical that causes local blood vessels to dilate?
This substance is called histamine.
What type of White blood cell release the chemical called Histamine?
Basophil granulocytes (usually called basophils) are the type of white blood cell that release histamine. This is an important part of inflammation.
The chemical released by white blood cells and causes redness and swelling?
The chemical released by white blood cells that causes redness and swelling is called histamine. Histamine is a key player in the inflammatory response and is responsible for dilating blood vessels and increasing blood flow to the affected area, leading to redness and swelling.
What is a leukocyte that releases histamine?
Both Heparin and Histamine are released by basophils and mast cells. These cells are very similar, but mast cells are found on mucous membranes (connective tissue) and basophils are white blood cells that travel in the blood in the circulatory system.
What chemical produced by white blood cells increase blood flow to an injured area?
Histamine is the chemical produced by white blood cells that increase blood flow to an injured area. It causes blood vessels to dilate, which allows more blood to flow to the affected area to deliver immune cells and nutrients for healing.
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.
How does a common cold virus affect the nose?
the cold virus attaches itself to the lining of the nasal passages and sinuses. This causes the infected cells to release a chemical called histamine. Histamine increases the blood flow to the infected cells, causing swelling, congestion
Does the histamine cause vasodilation?
Yes, histamine causes vasodilation. It is a chemical released by the immune system during allergic reactions and inflammation. Histamine binds to specific receptors on blood vessel walls, leading to the relaxation of smooth muscle and subsequent widening of the blood vessels. This process increases blood flow to the affected area, contributing to the symptoms of inflammation.
It releases chemical directly into the blood stream?
Intravenous injection.
Is histamine a neurotransmitter?
Histamine is a neurotransmitter produced by basophils (a type of white blood cell).
What is the effect of histamine on small as well as large blood vessels?
Histamine causes the dilation of the small blood vessels while constrict the large blood vessels.
