The Echo Dot is more compatible with more services and products than Googleâs, which makes it a better in-home, voice-controlled computer than the Home Mini is â at least at this point in time. The Dot also has a standard 3.5mm aux jack, and whether you think that sort of thing is necessary on a phone or not, it's undeniably useful on a little smart speaker.
The bone marrow produces B cells, natural killer cells, granulocytes and immature thymocytes, in addition to red blood cells and platelets. Thymus -- The function of the thymus is to produce mature T cells. Immature thymocytes, also known as prothymocytes, leave the bone marrow and migrate into the thymus.
The thymus, a specialized organ of the immune system, is primarily responsible for the T cellâs maturation. There are six types of T-cells, namely: Helper T-cells, Cytotoxic T-cells, Memory T-cells, Regulatory T-cells, Natural Killer T-cells (NKT) and Gamma Delta T-cells. B-cells, on the other hand, play a principal role in humoral immunity (with antibody involvement).
