Functions Of White Blood Cells And Immunization

<div dir="ltr" style="text-align: left;" trbidi="on"> People can protect themselves from serious diseases by carrying out immunization i.e artificial immunization.<br /> <br /> But then, what's immunization?  <br /> Immunization is the process of ingesting substances that is primed to make ones immune system  resistant to a specific pathogenic organisms or disease. Immunity created in the body is called natural immunization while the ones created by humans are called artificial immunity.<br /> <br /> Let's now know how artificial immunization is possible.<br /> <br /> We all know that the solid component of the blood known as the white blood cell carries out the important function of defending the body from pathogens or diseases. To make this more efficient,  the white blood cell is further categorized in two which include the phagocytes (that carry out phagocytosis, i.e ingestion of pathogens ) and the lymphocytes that secret substances called antibodies that function as follows in relation with the phagocytes.<br /> <br /> -Neutralization: the lymphocytes  neutralize the toxic produced by those pathogens or render them inactive.<br /> -Flocculation: The lymphocytes secret the disease causing organisms with antibodies that would cause them to clump together and then ingested by the phagocytes.<br />  Clotting: during the process of clotting, the lymphocytes got attached to the mesh of fibrin that block the cut and thus prevent the entry of pathogenic organisms.<br /> <br /> Let's break down the lymphocytes a bit further.<br /> <br /> The lymphocytes are further classified into two principal groups and the null-group.<br /> B-lymphocytes: produce antibodies in the humoral immune response.<br /> <br /> T-lymphocytes: participate in the cell mediated immune response.<br /> <br /> The null-group contains the cytotoxic cells (natural killer cells) and  participates in the cell innate immune response.<br /> <br /> It's now important to note that a particular type of pathogen stimulates the production of a particular antibody.<br /> <br /> How immunization works:<br /> The artificial immunization is simply aimed at making or creating an awareness of a possible presence a disease and causing the lymphocytes to recognize them.<br /> This is done by ingesting a small dose of dead or weakened causal micro-organism of such disease into the body.<br /> This will quickly draw the attention of the lymphocytes and thus effect the production of a specific antibody that would kill the disease.<br /> <br /> So when these white blood cells are destroyed,  the body is left defenseless and thus exposed to any possible disease or pathogen. This exactly what AIDS does.<br /> <br /> It attacks and destroys the white blood cells. The diseased is left defenseless and different diseases invade the body. This will lead to the actual death of the person. What Aids does is only destroying the body immune,then the different diseases that invade the body lead to the death of such.<br /> <br /> Got any suggestion?<br /> Use the comment space.<br /> <br /></div>

Why Well and Water Table Are Warm at Night or Morning During Winters

<div dir="ltr" style="text-align: left;" trbidi="on"> <div xmlns="http://www.w3.org/1999/xhtml"> It is widely noticed in our various life activities that well water and underground water are warm at night/morning but cold at the day during winters.<br /> In fact! Am a witness to that strange occurrence. Back in my childhood days, we usually ran to the well to draw water for our bath in the morning after comparisons has been made on the temperature of well, tank and underground water to normal ones.<br /> <br /> This sounds so ridiculous because the reverse is obvious with regards to the temperature differences at night and day and factors that effect temperature at whole. <br /> How comes this strange phenomenon? <br /> Why the reverse change in temperature? <br /> <br /> Let's see what answer nature has to offer us and the mystery behind this strange and odd...<br /> <br /> Let's study first the temperature of the atmosphere (which affects the water on the earth's surface) and the one beneath the earth or underground (which affect the water-table or underground water).<br /> <br /> Temperature on the earth's surface or atmosphere is easily influenced by external factors e.g weather conditions while the temperature beneath the earth crust is fairly constant ( fairly affected by changes).<br /> <br /> So if for example the normal temperature of the two kind of water in question is 1degree Celsius, after the heating of earth's surface by the sun and the cooling <a href="http://sciencezone12.blogspot.com/2014/10/the-higher-you-go-cooler-it-becomes.html"> read also-the higher you go, the cooler it becomes</a> the temperature of the water would drop below 1 degree Celsius but that of the underground water remain fairly constant e.g 1 degree Celsius. <br /> <br /> When we then touch the two water, we realize the underground is warmer than the other.<br /> <br /> Another reason is that heat of molten magma of any occurring intrusive volcanic eruption may affect the temperature of the underground water.</div> </div>
