Human physique consists of tens of millions of cells. The human physique faces assaults from micro-organisms, and different overseas substances. Physique has its personal defence mechanism. The mechanism will combat in opposition to the infections and the overseas substances. That is known as immunity. Some mechanisms are designed to determine the invaders and assault them. In these situations, the reminiscence cell will preserve in reminiscence the identification of the invaders and assault shortly when the identical invader comes subsequent time. This immunity is known as particular immunity. Lymphocytes are liable for particular immunity. The lymphocytes can determine the “enemy” and assault with particular antibodies and killer cells.
Different defence mechanisms can’t particularly determine the “enemy” however, can kill all overseas substances with out figuring out or retaining the identification. That is known as non- particular (innate) immunity. Macrophages are one sort of cells within the immune system, displaying innate immunity. Macrophage will encompass the overseas organism and “eat” it and kill it. Macrophages are often within the tissues. However lymphocytes are often within the lymphatic tissues or within the blood. Truly the MONOCYTE which is within the blood stream leaves the circulation and keep within the tissue as Macrophage. The macro means BIG. Phage means consuming. The macrophages are large in dimension and they eat the micro organism and viruses. Relying on the place it keep, the macrophages will get particular names; in liver it’s named as Kupffer cells, in bone osteoclast, within the lungs alveolar macrophage, and in mind micro glial cells.
In contrast with macrophage, the lymphocytes are small. In regular situation they don’t seem to be leaving the circulation. T lymphocytes can kill the contaminated cells (cyto poisonous), B lymphocytes will produce antibodies in opposition to the an infection.
- Each macrophages and lymphocytes are defence cells which defend our physique.
- Each cells are initially produced within the bone marrow.
- Lymphocytes are small in dimension in contrast with macrophages.
- Macrophages present phage (consuming the overseas physique) exercise, lymphocytes will not be.
- Macrophages keep within the tissue; lymphocytes are within the circulation,
- Macrophages give non-specific safety (innate immunity) however Lymphocytes give particular immunity.
