Students will review:
In this chapter, you'll learn the answers to questions including:
- How does blood coagulate and help wounds heal?
- What are the genetic factors associated with hemophilia?
- What are some common hematological conditions, and how are they treated?
- Is it possible to be born without an immune system?
- How do blood groups differ from each other?
- What types of reactions can occur during transfusions and transplants?
1. Blood Coagulation and Wound Healing
When your blood vessels suffer damage, your body follows a sequence of events to promote blood clotting. In this lesson, you will learn about coagulation cascade and important clotting factors involved in wound healing.
2. What is Thrombocytopenia? - Definition, Causes & Treatment
Thrombocytopenia is a blood disorder in which there are too few platelets in the blood. This results in problems with blood clotting. Learn about the causes of thrombocytopenia as well as treatment options.
3. Bleeding Out: ITP and Wiskott-Aldrich Syndrome
ITP and Wiskott-Aldrich Syndrome are bleeding disorders. Learn about the causes and symptoms of Wiskott-Aldrich Syndrome and ITP, which is also known as Immune or Idiopathic Thrombocytopenic Purpura.
4. What Is Hemophilia? - Symptoms, Genetic Cause & Treatment
In this lesson, you'll learn about a group of hereditary bleeding disorders collectively known as hemophilia. You'll learn why afflicted people don't form blood clots and why most hemophiliacs are males.
5. Von Willebrand's Disease: Types, Factors, and Treatments
Von Willebrand's disease is a bleeding disorder caused by a deficiency of von Willebrand factor, which is the glue that holds platelets together in the blood clotting process. Learn about the different types of von Willebrand's disease and treatments.
6. Polycythemia: Definition & Causes
Polycythemia is a blood disorder in which the body produces too many blood cells as a result of a problem with the bone marrow or an increased production of the hormone erythropoietin. Learn about the causes of polycythemia.
7. Thromboemboli: Definition, Causes & Treatments
Thromboemboli are blood clots that form within blood vessels and then circulate through the bloodstream. Learn about the problems associated with these blood clots as well as what causes them and how they are treated.
8. Disseminated Intravascular Coagulation: Definition & Causes
Disseminated intravascular coagulation is a disorder in which there is an over-activation of blood clotting in the blood vessels and resultant bleeding within the body. Learn about DIC and the underlying conditions that cause it to develop in this lesson.
9. Severe Combined Immunodeficiency: Causes, Symptoms & Treatment
Severe combined immunodeficiency is a genetic disorder that inhibits the body's ability to fight infections. This disorder affects children and results in increased susceptibility to infections. One possible treatment is a bone marrow transplant.
10. Blood Types: ABO System, Red Blood Cell Antigens & Blood Groups
You are either blood type A, B, AB or O. But, did you know that your blood type is determined by microscopic antigens found on your red blood cells? In this lesson, you will learn about the different blood groups and why they do not mix.
11. Transfusion and Transplant Reactions
A transfusion reaction occurs when incompatible blood is given to a recipient. A transplant rejection occurs when an incompatible organ or tissue is given to a recipient. Learn about these reactions and tests that are done to lessen their effects.
12. Acquired Immune Deficiencies
Immune deficiency means that the body has a lessened ability to fight infections. Immune deficiencies that result from an outside source are known as acquired immune deficiencies. Learn what puts you at risk and signs of immune deficiencies.
