What else can I help you with?
Does plasma cells eat invading antigens?
Yes. White blood cells eat the living and nonliving antigens that has entered in your body. They produce antibodies as a result.
Do white blood cells act as an antigens?
No, while some whte blod cells will attack and 'eat' invading patjhogens, an 'antigen' is a molicule.
These seek out and eat any invading germs?
white blood cells
Which type of cell eats invading cells?
The term for cells that eat is phagocytes. For example, macrophages which eat invading organisms in the human body would be called a phagocytic cell. "Phag" comes from the Greek which means "eat."
Which cell produces antibodies in the immune system?
B cells produce antibodies. Specifically plasma cells (a type of B cells, which are meant to produce large quantities of B cells very quickly, and memory B cells, which are meant to last in your body for a long time so you can respond to the same kind infection more quickly the next time.
How are the roles of b and t cells different how are their roles similar?
Both are T and B lymphocytes are produced in bone marrow, but B lymphocytes mature in bone marrow and are part of the humoral response, while T lymphocytes mature in the thymus gland and are part of the cell mediated response.
What are the differences between Bcell receptors and Tcell receptors?
there are different types of b cell and t cell. both are lymphocytes, a subclass of white blood cell. the t cells are mainly used in identifying antigens and releasing chemicals which attact macrophages (big immune cells which 'eat' antigens), to destroy the antigen. b cells are used in the production of antibodies. when they encounter a new antigen, plasma cells and memory cells are formed from the division of a b cell. the memory cell remembers the antigen and which antibody to use, while the plasma cell makes the antibodies to fight a particular antigen or class of antigens
What does the immune system do to a virus?
There are specialized white blood cells, the T cells, which identify invading viruses and tag them with an antibody, which then signals to other specialized white blood cells, the macrophages, to eat and digest the viruses.
How do antibodies inactivate antigens?
antibody form a complex like enzyme - substrate or in a lock & key hypothesis manner and in turn activate the other immune cells of body like macrophages , dendritic cells these cells in turn lead to the phagocytosis or digestion of the antibody .
What is the main role of the cells in a circulatory system?
It depends on the type of cell we're talking about. I'm going to use the assumption that you mean blood cells when you ask about the circulatory system cells (as opposed to the cells that make up the heart, arteries, veins and capillaries). Blood is made up of 4 major components: Red Blood Cells, White Blood Cells, Platelets, and Plasma. Plasma is the vast majority of blood and it's basically salt water that your cells float in and that carry nutrients and wastes through the body. Platelets are generally referred to as "cell fragments" that release thread-like proteins to help stop bleeding. Red blood cells have one primary role: Carry oxygen. That's it. "White blood cells" are a collection of many different types of cells that collectively work towards fighting infections. Some (macrophages) actually engulf and eat invading cells! Plasma cells create antibodies for remembering how to fight certain infections. Killer T-cells chemically attack infected cells. There are actually quite a few more. In all, there are 7 main types of cells (T-cells, B-cells, memory cells and plasma cells are actually subsets of the lymphocyte group).
3 ways that antibodies help destroy pathogens?
The antigen itself cannot destroy the pathogen but here are three ways it helps out:1. Antibodies can clump antigens together in order to enhance phagocytosis2. Antibodies can activate the cytotoxic cell responses (a chemical that destroys antibody-bound antigen).3. Antibodies can activate B lymphocytes, which results in the production on plasma and memory cells.
Why can your blood carry so many cells?
Blood contains plasma, a liquid made mostly of water, which allows it to carry a large number of cells. The cells in blood, including red blood cells, white blood cells, and platelets, are suspended in plasma and can be transported throughout the body for various functions such as oxygen transport, immune responses, and clotting.
