Blood Basics - The Cellular Constituents of Blood


Blood Banking is a multibillion dollar industry with employment opportunities that range from medical technologist to Registered Nurse. Each year over 21 million blood components are used in the United States alone. These 4 lessons will educate and invite students to understand and explore what happens behind the scenes of a blood bank. In this first lesson students explore the basic cellular constituents of blood and then apply this knowledge to a blood smear case study.


As students prepare to participate in blood drive, it is essential to review/relearn the form and function of the 4 main parts of the blood so they can prepare fact-based activities using this information.  Red and white blood cells, platelets and plasma are explored during this lesson with a fun interactive Kahoots quiz to check for understanding. The application component of the lesson deals with students understanding how a blood smear is made and how it is used to determine donor health at a blood bank. Since students will be creating a demonstration for the blood drive, it is necessary for them to get their hands on as many medical technologist tools as possible in each of the 4 lessons.
