There is external and internal so I'll list th external. The most important is skin then mucus, sweat or secretion, hair, nails and tears which are all part of the integumentary. Some internal defenses are white blood cells and T cells.
Halophiles are extremophiles that thrive in environments with very high concentrations of salt. <span>Halophiles prevent this loss of water by increasing the internal osmolarity of the cell by accumulating </span>osmoprotectants<span> or by the selective uptake of potassium ions.
