Which substance produces itching when released in response to allergens?
Allergen
Which connective tissue produces histamine?
Mast cells are the connective tissue cells that produce histamine in response to various stimuli, such as allergens or injury. Histamine is a key mediator of inflammation and allergic responses in the body.
What is the vascular effect of histamine released from mast cells?
Histamine released from mast cells primarily causes vasodilation and increased vascular permeability. This leads to the widening of blood vessels, resulting in increased blood flow to the affected area, which contributes to redness and swelling. Additionally, the increased permeability allows proteins and fluids to leak into surrounding tissues, facilitating the inflammatory response. These effects are crucial in the body's response to allergens and infections.
Why does the endometrium have many cells but no collagen and elastic fibers?
Because the endometrium is an epithelial tissue. Collagen and elastic fibers are produced by Fibroblasts which are found in connective tissue not epitheliam. Does that answer your question? Or do you want a more indepth response?
What is the definition Of Allergy?
An allergy is an immune system response to a foreign substance that is typically harmless to others, such as pollen, certain foods, or pet dander. This response can cause symptoms like sneezing, itching, or congestion.

Allergen
Histamine is released by what?
They are released by basophils and mast cells in nearby connective tissue.

Why do we get a runny nose?
A runny nose is typically caused by the body's immune response to viruses, allergens, or irritants. When these substances enter the nasal passages, the body produces extra mucus to trap and remove them, leading to a runny nose.
What chemical does your body release that promotes red swollen tissues?
Histamine is released by your body in response to allergens or irritants, leading to redness and swelling of tissues as part of the inflammatory response. This can happen in conditions like allergies, insect bites, or infections.
Why do we experience a runny nose?
A runny nose is often caused by the body's immune response to irritants like viruses, bacteria, or allergens. When these irritants enter the nasal passages, the body produces more mucus to trap and remove them, leading to a runny nose.
What is the overgrowth of fibrous tissue usually produced at the site of a skar?
The overgrowth of fibrous tissue at the site of a scar is called a keloid. Keloids occur when the body produces excessive collagen in response to the skin healing process, leading to raised and thickened scars that extend beyond the original wound boundaries. They can be itchy, painful, and cosmetically bothersome.
What is the body's response if the defense tactics don't work against the airborne allergens?

Is the body's immune response to allergens which are antigens that produce a hypersensitivity reaction including immediate inflammation?
Allergy
What's the definition of Allergies?
Allergy is a hypersensitive elicitation of immune response of body upon exposed to some allergens.
Which organs do allergens mainly affect?
Allergens primarily affect the respiratory system, leading to symptoms such as sneezing, nasal congestion, and asthma. They can also impact the skin, causing conditions like eczema or hives. Additionally, allergens may influence the gastrointestinal system, resulting in food allergies that cause nausea or abdominal discomfort. Overall, the immune response to allergens can involve multiple organ systems.
What gland produces epinephrine and norepinephrine?
The adrenal gland (more specifically the Adrenal Medulla).
