How do histocompatibility antigens help the immune system in recognizing and distinguishing between self and non-self cells?
Histocompatibility antigens, also known as human leukocyte antigens (HLAs), help the immune system recognize and distinguish between self and non-self cells by serving as markers on the surface of cells. These antigens play a crucial role in immune responses by allowing the immune system to identify and target foreign invaders while avoiding attacking the body's own cells.
How many types of antigens on the erythrocytes?
There are two main types of antigens on erythrocytes - ABO antigens and Rh antigens. ABO antigens include A and B antigens while Rh antigens include RhD antigen. These antigens play a crucial role in determining blood type compatibility for blood transfusions.
What is the main function of proteins in the human body?
Proteins play a crucial role in the human body by serving as building blocks for tissues, enzymes for chemical reactions, and antibodies for immune defense.
What role do proteins play in the functioning of the human body?
Proteins are essential molecules that play a crucial role in the functioning of the human body. They are involved in various biological processes such as building and repairing tissues, regulating chemical reactions, and serving as messengers within cells. Proteins also play a key role in the immune system, transport of molecules, and providing structure to cells and tissues. Overall, proteins are vital for the proper functioning of the human body.
What is the role of tough tissue that connects muscles in the human body?
The tough tissue that connects muscles in the human body is called tendons. Tendons play a crucial role in transmitting the force generated by muscles to the bones, allowing for movement and stability in the body.
What plasma proteins is involved in neutralising antigens?
Immunoglobulins, specifically IgG antibodies, play a key role in neutralizing antigens by binding to them and enhancing their removal from the body. These proteins are produced by B lymphocytes in response to the presence of antigens.
What self antigens is found on cell membranes?
Major histocompatibility complex (MHC) proteins, also known as human leukocyte antigens (HLAs), are self antigens found on cell membranes. These proteins play a key role in presenting foreign antigens to the immune system for recognition.

These antigens play a crucial role in immune responses by allowing the immune system to identify and target foreign invaders while avoiding attacking the body's own cells.
What are molecules on the outer surface of a cell that identify it as long friend or for?
Molecules on the outer surface of a cell that identify it as "self" or "foreign" are called antigens. These antigens play a crucial role in the cell's ability to distinguish between its own cells and potentially harmful foreign cells. The recognition of self-antigens helps the immune system to tolerate the body's own cells while identifying and attacking foreign invaders.
What is neutralizing antigen?
Its the antigen in a particular foreign body or pathogen that the body recognizes as "allo" or unfamiliar.. Maybe even harmful. So antibodies are produced against these antigens. And since they are 'neutralizing antibodies' it follows that the antigens they bind to are 'neutralizing antigens'
How many types of antigens on the erythrocytes?
There are two main types of antigens on erythrocytes - ABO antigens and Rh antigens. ABO antigens include A and B antigens while Rh antigens include RhD antigen. These antigens play a crucial role in determining blood type compatibility for blood transfusions.
What part x play in the human body?
xyphoid
Specialized cells that attack foreign substances upon recognizing the foreign surface antigens are called?
These specialized cells are called immune cells, particularly T cells and B cells. They play a crucial role in the body's immune response by identifying and responding to foreign antigens to eliminate them and protect the body from infections.
Does yeast grown on the human body?
Yeast normally colonize the human body, especially in areas like the mouth, gut, and skin. They play a part in maintaining the balance of the body's microbiome. However, overgrowth of certain yeast species, like Candida, can lead to infections if the immune system is compromised or there is a disruption in the body's natural balance.
How does the appendix help to the immune system of the body?
As of yet, the purpose of the appendix in the human body is not known. It is simply there and is often removed. Anyhow, appendix do play role in fetal development and adult.In fetus appendix act as a endocrine organ and in adult they help our body immune system to combat against microbes as it 'train' our immune system by exposing antigens to lymphoid cells in order to produce antibody.
Silicon in the body?
Silicon is naturally present in the body, particularly in connective tissues, skin, hair, and nails. It is important for the formation of collagen, which helps in maintaining the skin's elasticity and strength. Silicon is also believed to play a role in bone health and wound healing.
What is the location of HLA1 and HLA2?
HLA1 and HLA2 are located on chromosome 6 in the human genome. They encode proteins that play a key role in the immune system by presenting antigens to T cells for immune responses.
