6 Plasma Is a mixture of: Water (92%) Sugar Fat Protein potassium and calcium salts.
7 Red Blood CellsContain a special protein called hemoglobin, which carries the oxygenHemoglobin also makes red blood cells red.
8 White Blood Cells Bigger than red blood cells. Produce antibodies that help our bodies fight infections caused by bacteria, viruses, and foreign proteins.
9 Platelets Are just fragments of cells. When we are injured, platelets gather at the site of the injury and stick to the edges of the wound. They release chemicals that help start the process of blood clotting so that bleeding will stop.
10 Blood Type is Inherited Everybody has a blood type. The most common blood type classification system is the ABO (say "A-B-O") system discovered by Karl Landsteiner in the early 1900s.
11 Three Alleles for ABO Blood BLOOD TYPES: A B AB OABO
24 Rh Factor: another antigen-antiody combo * Rh reactions vary in strength from slight to very strong agglutination. If the Rh antibody finds Rh antigens on red blood cells, we say the person's blood type is positive (+).
31 Which type is most common? O Rh-positive--- 38 percent O Rh-negative--- 7 percent A Rh-positive--- 34 percent A Rh-negative--- 6 percent B Rh-positive--- 9 percent B Rh-negative--- 2 percentAB Rh-positive--- 3 percent AB Rh-negative--- 1 percent
32 Donating BloodPeople with blood group O are called "universal donors" and people with blood group AB are called "universal receivers."
38 Can you have 2 blood types? NOTE: A small number of people have two different ABO blood types. They are not simply AB codominant. Apparently, most of these blood chimera individuals shared a blood supply with their non-identical twin before birth. In some cases, people are unaware that they had a twin because he or she died early in gestation and was spontaneously aborted. As many as 8% of non-identical twins may have chimeric blood.
