My blood runs cold…..

OVERALL FUNCTIONS Transport Nutrients and waste Body heat Immunity

Parts and function Formed elements: Erythrocytes Leukocytes Platelets PLASMA -proteins ***SEE FIGURES 10.4 and 10.5 for formation of blood cells

Erythrocytes Red blood cells 5 million per cc Hemoglobin to carry O 2 Shape= surface area 1 RBC=250 millon hemoglobin 1 hemoglobin=4 O 2 molecules

Leukocytes /cc Different types-see lab Can “smell” different chemicals emitted in response to pathogens and move like an amoeba to it. They can get in and out of blood vessels

Platelets 3000/cc Used in clotting

Clotting

Genetics of blood type A (I A ) and B (I B ) are dominant to O (i). When A and B occur together, the person is AB

Paternity test “Dad” 1 is A “Dad” 2 is B “dad” 3 is AB Mom is O If the child is O, what are the chances of each being the father? What if the child is A?

Rh factor There are also Rh antigens Someone who has it is Rh+, if you don’t you are Rh- and make Rh antibodies This is important during pregnancy
