A certain cell type has existed in the blood and tissue of its vertebrate host's immune system for over twenty years. One day, i
t recognizes a newly arrived antigen and binds to it, subsequently triggering a secondary immune response in the body. Which of the following cell types most accurately describes this cell? a. plasma cell
b. thyroid cell
c. memory cell
d. macrophage
Memory cell is a long-lived immune cell that has the capability of recognizing a foreign particle that it has previously encountered and consequently mount a quicker and stronger immune response. Because this cells are able to recognize foreign antigens they have previously encountered hence, the name memory is used.
These cells exist in the blood and tissue of its host's immune system for a very long period of time.
Memory cell are divided into two (2) categories, namely;
a. Memory B cells
b. Memory T cells
Memory B cells produce antibodies triggering a subsequent secondary immune response while Memory T cells do not produce antibodies.
Memory cells are long-lived immune cell that can recognize a foreign particle that it previously encountered and consequently fight it by providing or building a faster and stronger response for the immune system.
The memory cells don't respond immediately when it recognizes the foreign particle, but, provides a faster response when it encounters the particle subsequently.
The memory cells are long lived immune cells which means they can live in a system for a vey long period.
