T cells or T lymphocytes are a type of lymphocyte (in turn, a type of white blood cell) that plays a central role in cell-mediated immunity. They can be distinguished from other lymphocytes, such as B cells and natural killer cells (NK cells), by the presence of a T-cell receptor (TCR) on the cell surface. cells or T lymphocytes are a type of lymphocyte (in turn, a type of white blood cell) that plays a central role in cell-mediated immunity.

Definition of Health According to WHO. World Health Organization (WHO), defined Health as being âa state of complete physical, mental, and social well-being and not merely the absence of disease or infirmityâ in 1948. Since then only few of the publications believed on the definition of health and its evolution in the first 6 decades.
And many people who are suffering from some known disease, may be relatively healthy. Health is a concept which does not merely relate to the absence of disease, of healthy working of organs, or having good thoughts. Health is a holistic concept. It relates to a person as a whole. Not just the person you see, but also the person you âfeelâ. Health is a tri-une of three parts: - Emotional Health-Mental Health-Physical Health.
