Develop as outpocketing of developing vein from mesoderm

A

Lymphatics

35
Q

Develops from endoderm

A

Thymus

36
Q

The rest of the lymphoid organs develop from

A

37
Q

Defense of the body against disease causing agents like transplant, blood transfusion, autoimmune, allergies, aids

A

Immunity

38
Q

Immunity can be divided into two

A

Specific or non-specific

39
Q

These immunity response block the entry or spread of the disease

A

Non-specific response

40
Q

This immunity response is very specific which is tailored to individual treat and possesses antibody mediated B cells and cells mediated t cells

A

Specific

41
Q

What cell is antibody mediated

A

B cells

42
Q

What cell is cell mediated

A

T cells

43
Q

This is an immune response present at birth which is non-specific and does not become efficient upon the second exposure to same organism

A

Innate immunity or non-specific immune response

44
Q

These include skin, mucous membrane, phagocytes, natural killer cell, inflammatory response, interferon, complement, fever

A

Innate immunity or non-specific immune response

45
Q

This is an immune response following certain infection which has antigen and antibody reaction

A

Acquired or adaptive or specific immune response

46
Q

It is antibody meditated immunity

A

B lymphocytes humoral

47
Q

It attacks the infected cells virus cancer cells are foreign body

A

Cytotoxic T cell

48
Q

Terminates normal immune response
