T Cells And B Cells

T Cells

Definition

T cells are a type of white blood cell that play an important role in the immune system.

Origin

T cells are produced in the bone marrow and mature in the thymus gland.

Functions

T cells are responsible for recognizing and destroying cells that have been infected with a virus, as well as cancer cells. There are several different types of T cells, including helper T cells, cytotoxic T cells, and memory T cells.

Types of T Cells

  • Helper T cells are responsible for activating other immune cells, such as B cells and cytotoxic T cells.
  • Cytotoxic T cells are responsible for directly attacking and destroying cells that have been infected with a virus or that are cancerous.
  • Memory T cells are long-lived cells that are capable of recognizing and responding to a pathogen that the immune system has previously encountered.

B Cells

Definition

B cells are a type of white blood cell that play an important role in the immune system.

Origin

B cells are produced in the bone marrow.

Functions

B cells are responsible for producing antibodies that are specific to a particular pathogen. When a B cell encounters a pathogen, it produces antibodies that are specific to that pathogen. These antibodies then bind to the pathogen and mark it for destruction by other immune cells.

Types of B Cells

B cells also have the ability to develop into memory B cells, which are capable of producing antibodies in response to a pathogen that the immune system has previously encountered.

In conclusion, T cells and B cells are two types of white blood cells that play important roles in the immune system. T cells are responsible for recognizing and destroying cells that have been infected with a virus or that are cancerous, while B cells are responsible for producing antibodies that are specific to a particular pathogen.
