Three PowerPoint presentations cover human blood physiology for high school anatomy and physiology classes: a 14-slide deck on platelets and blood physiology, a 14-slide deck on red and white blood cells, and a 12-slide deck on blood types, transfusions, and blood disorders. Across the set, direct-instruction slides — covering hemoglobin's oxygen-carrying role, the three plasma proteins (albumin, globulin, fibrinogen), the five white blood cell types, and ABO blood typing — are accompanied by question-and-answer review slides in the platelet and blood-types decks, such as naming erythropoiesis's controlling hormone or recalling the names of the formed elements. The editable PowerPoint format lets a teacher reorder slides or adjust wording before presenting the three-part unit.
