Blood-Mwahahahaha!!

Blood Typing

Patient 1 had a blood type of AB+. I was able to discern this because her blood agglutinated in the A, B, and Rh test tubes. Under the microscope, it was apparent that she had all three antigens present on her RBCs, and that the A, B, and Rh antibodies were attacking them. Three bags of blood were required for transfusion, so I chose AB+, A+, and B+, all of which were helpful. Patient 2 had B+ blood, as his blood agglutinated in the B and Rh test tubes. Under the microscope, his blood showed B and Rh antigens which were attacked by their respective antibodies, but no A antigen, so the A antibodies didn't attach and clump it together. Four bags of blood were required at transfusion, so I chose B+, B-, O+, and O-, which all worked. Patient 3 was B-. His blood only agglutinated with the B test tube and only showed a presence of B antigens. Two bags were required for transfusion, so I used B- and O-, the only two that would not cause an Rh reaction. I received a total score of 5 out of 5 blood drops, which makes me either a great future ER doctor, or an excellent blood-sucking vampyre.

Leukocytes

Basophils-.5% Rare

Theses histamine-containing granular leukocytes help initiate the inflammatory response of the body. When tissues are injured, basophils secrete histamine, causing adjacent blood vessels to leak plasma, bringing nutrients, cells and chemicals necessary for repair to the damaged area.

Eosinophils-2%-4%

These granular leukocytes defend against large parasites, such as hookworms and tapeworms(ewwwww!)by bombarding them with digestive enzymes.They also release chemicals that moderate allergic reactions.

Lymphocytes-30%

These agranular leukocytes are found in the spleen, tonsils, lymph nodes, and thymus gland, in addition to the blood stream. B lymphocytes create plasma cells that produce antibodies, and T lymphocytes target specific threats such as cancer, bacteria and viruses.

Monocytes-5%

The largest of the WBCs, these agranular leukocytes make their way out of the bloodstream and live in various tissues. Depending on where they end up, they become various macrophages that engulf nonself cells and cell debris. They increase with the presence of chronic infections.

Neutrophils-60% Most Common

Neutrophils are the first on the scene of an infection, and their numbers increase drastically during acute bacterial infections. These granular leukocytes surround and engulf the bad guys, especially bacteria and a few fungi.
