Question

list the immune responses characterized as specific (aquired) immunity.

Answer 1

The list of immune responses characterized as acquired or specific immunity are

1) The humoral and the cell mediated immune responses

The adaptive immunity is usually not resent in a human's body during birth , it is acquired after birth. It is very specific to the antigen that attacks the body

The T cells and the B cells are the active immune cells , that are responsible for elucidating the specific immune response

T cells

The T cells are the T lymphocytes destroy a foreign antigen or abnormal cells of the body by recognizing them through specific fragments that are attached on the surface of the antigens . These fragments are laid by various cells such as

• Killer T cells
• Helper T cells
• Suppressor T cells

With the help of the cells mentioned above the T cells destroy the pathogen

B cell

B cells are the cells that produce the antibodies against the antigens that encounter the body. They elucidate 2 types of responses

The primary response

The antibody is created for the first time when the pathogen enters the body

Secondary response

This is caused by the memory B cells , that remembers the antigen during its second attack to the body . This time the defense mechanism gets stronger and more effective against the pathogen . The vaccinations are designed by exploiting this character of the B cells

The acquired immunity may be natural or artificial

Natural Acquired immunity

It is of 2 types Passive and active. Passive natural acquired immunity is attained from the mother to the infant through breast milk . Active natural acquired immunity is attained when there is an infection encountered by the body by the B memory cells

Artificial Acquired immunity

Artificial acquired immunity is also of 2 types , the active and the passive

The active artificial acquired immunity is attained by vaccines , the passive artificial acquired immunity is given by injecting antibodies to provide immunity
