Summary Introduction
Introduction:
The immune system can be defined as the organs and body processes that resist the infection and toxins. This system includes the organs such as bone marrow, thymus, and lymph nodes. Lymphocytes are of two types: B cells and T cells. B cells play a role in cellular immunity. T cells help in the antibody/humoral immunity. These exist throughout the body.

FIRST statement is TRUE; SECOND statement is FALSE
Some immune systems fail to work effectively so the person is less protected than others. This type of disease or medically induced condition is called ___.
atelectasis
anergy
protein deficiency
immunosuppression
Lymphocytes that develop immunocompetence in the thymus are __________lymphocytes.
We put everything in our mouth since our childhood. Therefore our mouth is full of live bacteria. These bacteria are potentially dangerous if they cross our gut wall into our blood circulation. Fortunately we are protected from them by our gut's mucosal lining and the cells (macrophages, dendritic cells, B and T lymphocytes) in the lymphoid tissue called [a] (enter two words). This structure play a crucial role for the development of food tolerance or food [b] (enter one word), coeliac disease and chronic inflammatory bowel disease.
