Anemia: Reduced Oxygen Capacity
- Iron deficiency anemia: Not enough iron for hemoglobin production
- Symptoms: Fatigue, pale skin, shortness of breath
- Treatment: Iron supplements, dietary changes
Leukemia: White Blood Cell Cancer
- Cause: Uncontrolled production of abnormal white blood cells
- Effect: Overcrowds normal blood cells, impairs immunity
- Treatment: Chemotherapy, bone marrow transplant
Clotting Disorders
- Hemophilia: Genetic deficiency in clotting factors, excessive bleeding
- Thrombosis: Unwanted clot formation, can block blood vessels
- Deep vein thrombosis: Blood clots in leg veins, can travel to lungs

Practice questions for Blood Components and Vessels
What is the main function of red blood cells?
Explain how red blood cells are adapted for their function of transporting oxygen.
Quick recall flashcards
What are platelets?
Small cell fragments with no nucleus that help blood clot by sticking to damaged vessels and releasing clotting factors.
What is hemoglobin?
A protein in red blood cells containing iron that binds reversibly with oxygen to transport it around the body.
