Drip irrigation can be used under certain conditions.

Antigen Extraction Tube

Antigen extraction cells refer to a class of cells that can take up, process antigens and present antigen information to T lymphocytes, also known as helper cells. In the process of thymus-dependent antigen inducing B lymphocytes to produce antibodies, not only the synergistic effect of T and B lymphocytes is required, but also the assistance of another type of cells, so this type of cells is called helper cells. It plays an important role in the body's immune recognition, immune response and immune regulation.
