What cells are primarily responsible for the formation of areolar connective tissue?
fibroblastsfibroblast, macrophages, mast cellsfibroblast, macrophages, and mast cells
What cells types are likely to be found in the dermis?
Fibroblast, macrophages, and occasionally mast cells and white blood cells.
What cells act as phagocytes?
1-Neutrophils. 2-Monocytes. 3-Macrophages. 4-Dendritic cells ( anti-gen presenting cells ). 5-Mast cells.
Which cells phagocytize an antigen?
They are "phagocytes." Phagocytes include cells called neutrophils, monocytes, macrophages, dendritic cells, and mast cells. NEUTROPHILS - first line of defense mechanisms. MACROPHAGES - second line of defense mechanisms. Phagocytosis is a process by which macrophages (a type of white blood cells) engulf pathogens and cell debris.
What are the tissues of the immune system?
The lymphatic tissues, white blood cells, the cells of Langerhans, B-cells, T-cells, tonsils, lymph nodes, pancreas, bone marrow, mast cells, wandering lymphocytes, wandering macrophages, type I lung cells and quite a few other types
Which type of leukocyte contains heparin and anticoagulant?
Basophil is the type of leukocyte that contains heparin and is an anticoagulant. The type of leukocytes that become macrophages in the tissues are monocytes.
What occurs when mast cells and basophil cells degranulate?
When mast cells degranulate, the release histamines
What cell type initiates inflammatory responses to infection or tissue damage?
The cells involved in inflammation are the cells that release cytokines which include: interferons, tumor necrosis factor, interleukins, and chemokines. All of which can result in inflammation since they increase vascular diameter leading to an increase in blood flow and they also attract phagocytic cells that release inflammatory mediators causing pain. These cells include macrophages, neutrophils,and eosinophils.
Mast cells lead to allergic response which might be harmful to human body then why are mast cells present in your body and how are they useful to the body?
Mast cells are helpful to the physical body because they help iniate an inflammatory response. Inflammation is used by the physical body to defend it'self against incoming antigens that could potentially harm the body. Inflammation is an immune system adaptation and most sources refer to it as a secondary form of non-specific immunity. The reason Mast Cells are usefull is because they are the cells that have cell identity markers on them. Mast cells are a type of wbc that differentiates into a mast cell when it leaves the cardio-vascular system and moves into the tissue. Mast cells are able to recognise a potentially harmful substance. The value of this is that mast cells are able to produce and allergic reaction and this attracts macrophages and other WBC's which ensure that the potentially harmful substance is isolated and distroyed. The body sees the positive aspect of removing the potentially harmful substance as more important than the negatives associated with inflammation.
What do cells release?
Mast cells release histamines which will dilate small blood vessels during inflammation.
What actively phagocytic leukocytes?
To ingest invading microorganisms that have breached external defenses.
Can you give me sentences using the word mast cells?
Mast cells degranulate to release histamine.
