Thus, the determinant gene of ABO blood type for instance is found on chromosome 9 and is referred to as glycosyltransferase .In addition, the ABO locus is made of 3 key allelic kinds: A, B and O as discussed above and every one of them was responsible for the production of its glycoprotein better known as antigens which are always found in the blood cells of an individual and thus their ABO blood group.
Therefore the A as well as B blood types are due to various antigens (they provoke immune responses) on the red blood cells’ surface. The production of antigens is usually under the DNA. Thus antigens emanate from a red blood cell surface precursor known as H substance-common to A,B as well as O. Placement of N-acetylgalactosesamine results in type A enzyme which is transferase on the H kind of substance. The attachment of galactose to H by group B transferase resulted in the formation of group B (Daniels, 2013).
On the other hand, type O comes about from a basic joint mutation that adversely destroyed or reduced the potential of Type A transferase to attach the mandatory N-acetylgalactosesamine to H substance. As studies have shown on monkeys, human blood types are very archaic genetic indicators which have been evolving for several million years ago. On the basis of primary races thesis hypothesis. In addition, it has always been held that the 3 main races of man, Europe blood group A, Asian blood type B and eventually blood group O in South America. These 3 groups have been emerging gradually because of the mixing and migration of the races leading to the current situation (Daniels, 2013).
Another postulation about the origin of blood types is that emergence of every blood group A and b as well as their subgroups was as a result of successive ...Download file to see next pagesRead More

...?Blood pressure is a measure of tension exerted by blood against the walls of the arteries. It de s the force of ventricular contraction, the resistance within the arterioles and the capillaries and the volume and viscosity of blood. Accurate measurement of blood pressure in the presence of findings in the history and physical examination of a patient can bring to light a diagnosis that may pertain to any of the above factors. This is why measurement of blood pressure is an integral part of general as well as cardiovascular examination. There are several processes that control the blood pressure.

Mixed Blood
...Mixed Blood s In the article “Mixed Blood”, the writer, Jefferson.M.Fish explores the human perception of the term “race”. At the very beginning of the article we come to know about the author’s stance on the topic i.e. he does not believe that race is any biological entity and is purely a myth.

Blood Pressure
...Insert Introduction During the laboratory activity, systolic blood pressure (the maximum pressure exerted by the blood against the artery walls) of the test subject was 110 at rest. However, this pressure increased to 120 and 140 when subject was placed under 1kg and 2.5 kg workloads respectively. This was the case as blood flow has to increase during strenuous activity (exercise) in order to supply nourishment (oxygen and nutrients) to critical organs such as the heart, brain, lungs and muscles. At the same time, diastolic pressure (the lowest pressure in the artery) at rest was measured at 70 but decreased to 50 then 40 at 1 kg and 2.5 kg workloads respectively. Diastolic pressure is a...
