Mississippi Science HAP.9

ScienceGrades 9–12Human Anatomy and Physiology

Standard Cluster

Students will analyze the structure and functions of blood and its role in maintaining homeostasis. Describe the structure, function, and origin of the cellular components and plasma components of blood. Distinguish the cellular difference between the ABO blood groups and investigate blood type differences utilizing antibodies to determine compatible donors and recipients. Research and analyze the causes and effects of various pathological conditions (e.g., anemia, malaria, leukemia, hemophilia, and blood doping). Enrichment: Use an engineering design process to develop effective treatments for blood disorders (e.g., methods to regulate blood cell counts or blood doping tests). *

What This Cluster Means

What Students Need to Do

Students explain what red cells, white cells, platelets, and plasma do to keep the body stable. They trace blood cells to bone marrow and identify water and proteins in plasma. They use antibody reactions to check blood type and donor matches, then connect blood disorders to changes in blood function.

What Mastery Looks Like

A student can explain how red cells carry oxygen, white cells fight infection, and platelets and plasma proteins help blood clot. They can read anti-A and anti-B test results and choose safe red-cell donors. Given a low hemoglobin result, they can explain why the patient may feel tired.

Common Misconceptions

Students may think ABO letters name antibodies, rather than markers on red cells. They may call platelets whole cells or assume all bleeding problems come from too few platelets. They may also assume a high white cell count always means infection.

How to Assess It

Exit ticket: A patient has a low red cell count, and their blood clumps with anti-A but not anti-B. Name their blood type, list compatible red-cell donors, and explain one likely symptom.

Ways to Teach It

  1. Use simulated blood, anti-A and anti-B test solutions, and a spotting tray to type four mystery samples by clumping.

  2. Give pairs an anemia case and a hemophilia case; ask which blood component fails in each and what symptom follows.

  3. Deal ABO donor and recipient cards; have students match safe red-cell transfusions and explain why two rejected matches are unsafe.

  4. Show a cyclist's rising hematocrit chart; ask how blood doping could improve oxygen delivery while increasing clot risk.
