Seminal fluid, otherwise known as semen, is an organic material that is produced by the body more specifically the sexual organs like the gonads and testes. It contains spermatozoa which are the natural cells known as sperm. Simply put the body produces semen, which contains sperm. The seminal fluid is acts a protective barrier for the sperm cells and helps nutrition for the sperm cells as they navigate their way through the female reproductive system. The female reproductive system is acidic whereas the composition of semen is very basic and prefers an alkaline environment.
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.
T C cells, or killer T cells, are the only T cells that can directly attack and kill other cells. They circulate throughout the body in search of body cells that display the antigen to which they have been sensitized. Their targets include: Virus-infected cells.
