Find the Foldable from Yesterday! Find the antigen to each RBC (A, B, AB, and O). Cut these out and paste the appropriately. Hint: What does each cell look like? Find the antibody that WOULD not match to the antigens found in step 1 for each antigen! For each RBC type, which blood type (s) can they give blood to? Remember, if anything matches, it causes agglutination. For each RBC type, which blood type (s) can the receive blood?

What presumptive tests do we use to detect blood and what would you see? Presumptive Tests: 1. Kastle Meyer (turns pink) 2. Hemastix (tetramethylbenzdine) (turns blue) 3. Leucomalachite Green (green-blue) 4. Luminol/ Bluestar (glows blue!)

Blood Evidence Blood samples – Can be analyzed to determine blood type and DNA, which can be matched to possible suspects. Blood droplets – Can be analyzed to give clues to the location of a crime, movement of a victim, and type of weapon. Blood spatter – Can be analyzed to determine patterns that give investigators clues to how a crime might have happened.

Rh Factors A+ A- B+ B- AB+ AB- O+ O- Scientists sometimes study Rhesus monkeys to learn more about the human anatomy because there are certain similarities between the two species. While studying Rhesus monkeys, a certain blood protein was discovered. This protein is also present in the blood of some people. Other people, however, do not have the protein. The presence of the protein, or lack of it, is referred to as the Rh (for Rhesus) factor. If your blood does contain the protein, your blood is said to be Rh positive (Rh+). If your blood does not contain the protein, your blood is said to be Rh negative (Rh-). A+ A- B+ B- AB+ AB- O+ O- http://www.fi.edu/biosci/blood/rh.html

How common is your blood type? 46.1% 38.8% 11.1% 3.9%

You can choose to have students draw this into their notebook or you can print this slide out for them to glue/tape in. I suggest printing 2-4 to a page to save paper and fit into the notebook without folding. I have my students write a summary piece at the bottom to demonstrate mastery. If you use a digital notebook, they can screenshot or copy/paste this picture.

The blood would agglutinate (clump) and the person could die Checkpoint... Describe what you think would happen if someone with type “A” blood gets a transfusion with type “B” blood The blood would agglutinate (clump) and the person could die Answer will appear on click © Schilly Science

Blood Transfusions O A B AB A blood transfusion is a procedure in which blood is given to a patient through an intravenous (IV) line in one of the blood vessels. Blood transfusions are done to replace blood lost during surgery or a serious injury. A transfusion also may be done if a person’s body can't make blood properly because of an illness. Who can give you blood? People with TYPE O blood are called Universal Donors, because they can give blood to any blood type. People with TYPE AB blood are called Universal Recipients, because they can receive any blood type. Rh +  Can receive + or - Rh -  Can only receive - A B O AB Universal Donor Universal Recipient
