Are goblet cells assigned with any other function than secreting mucin?
Goblet cells are mainly responsible for secreting mucin to protect and lubricate the surface of the gastrointestinal and respiratory tracts. They also play a role in initiating immune responses by presenting antigens to immune cells and producing certain enzymes and cytokines.
What protects the body from free antigens?
The immune system protects the body from free antigens. It does so through the production of antibodies that recognize and neutralize antigens, as well as through the activation of immune cells, such as T cells and natural killer cells, that can directly destroy cells infected with antigens. Additionally, the immune system has memory cells that can recognize and respond more quickly if the same antigen is encountered again in the future.
What types of antigens are recognized by B cells?
Processed fragments of protein antigens displayed on surfaces of body cells.
Which cells exhibit clonal diversity?
Cells of the immune system, such as B cells and T cells, exhibit clonal diversity. They undergo rearrangement of their antigen receptor genes to generate a diverse repertoire of cells capable of recognizing a wide range of antigens. This clonal diversity allows the immune system to respond to a variety of pathogens and antigens.
Mucus secreting goblet cells aren't found in what organ systems?
Mucus-secreting goblet cells are not found in the nervous or skeletal systems.
Do T- Cells respond to antigens by becoming plasma cells?
No. B-Cells do.

What do plasma cells form from?
Plasma cells form from B cells that have been specifically activated by antigens. Upon activation, B cells differentiate into plasma cells which are responsible for producing and secreting antibodies to fight off pathogens.

What is lymphocytes contained in the thymus gland that acts on antigens?
T cells are the lymphocytes contained in the thymus gland that act on antigens. They undergo maturation and selection processes in the thymus to ensure they can recognize and respond to specific antigens. These T cells play a crucial role in the immune response by recognizing and attacking cells infected with pathogens.
What does not respond to cell-mediated immunity?
Non-living things such as toxins, chemicals, and drugs do not respond to cell-mediated immunity since they do not have cells or antigens that can be recognized and targeted by the immune system's T cells.
When the immune system does not respond to a particular antigen?
Tolerance exists when the immune system does not respond to a particular antigen. All cells and tissues in the body contain antigens that normally do not stimulate an immune response. The immune system is said to exhibit tolerance toward such antigens.
What types of antigens are recognized by B cells?
Processed fragments of protein antigens displayed on surfaces of body cells.

Mucus secreting goblet cells aren't found in what organ systems?
Mucus-secreting goblet cells are not found in the nervous or skeletal systems.
What typoes of cells produce antigens?
All cells produce antigens, or cell surface markers. The only question is whether the antigens are self antigens which means they belong in the body or they're foreign antigens which means they are an invading bacteria or virus (or a cancerous cell).
Is an animal's stomach is a example of a specialized cell?
No, an animal's stomach is an organ made up of several different types of specialized cells, such as mucous-secreting cells, acid-secreting cells, and digestive enzyme-secreting cells. These cells work together to carry out the function of the stomach, which is to break down food for digestion.
