Question
A patient has a blood cell ratio of I WBC: 300 RBC. What 2 clinical words could be applied to this condition? 2. 3. People who live at high altitudes often have polycythemia. Describe this condition and a possible reason it occurs at high altitudes where there is less oxygen. Hint: Think of a possible benefit resulting from the condition.) 4. Can blood types be used in forensic/crime cases to prove or disprove guilt? Give examples to support your answer. 5. Name the antigens present on the RBCs and the antibodies present in the plasma of these blood types: Antigens of RBCs Antibodies in Plasma O+ B- AB+Explanation / Answer
2. When a patient is suffering from such blood cell ratio then we can say that in case of WBCs the patient is suffering from any viral infection and its blood cell ratio decreases and condition is known as leukopenia and in case of RBCs the patient is in high altitude so its RBCs count increases. So condition is known as polycythemia.
3.People who live at high altitude often suffers from polycythemia because the air is thinner at high altitudes that is fewer oxygen molecules are available per volume of air. So to compensate with this decrease of oxygen one of the body's hormone erythopoietin triggers the production of more red blood cells to aid in oxygen delivery to muscle cells.so in this way RBCs number increases and the condition is known as polycythemia.
4.Yes blood types can also be used in forensic/ crime cases to prove or disprove guilt because parents may have different blood group from their children and indeed sibilings may also have different blood groups but through the use of DNA fingerprinting it is possible to draw up certain characteristics that are shared between father, motherand their offspring this is called mitochondrial DNA and can be found all the way through a family blood line over many generations. These blood types although used as a means of collating DNA evidence, accounts for means of identification and guilt.
4. O+ : neither antigen A and B on red cells but has both antibody a and b on surface of plasma.
AB+:Both have antigen A and B in red blood cells but no antibody a and b on surface of plasma. Also known as universal acceptor.
A- : has only A antigen in red blood cells and B antibody on surface of plasma.
B- : has only B antigen in red blood cells and A antibody on surface of plasma.
