Blood Coagulation and Wound Healing

1. Blood Coagulation and Wound Healing

After suffering a wound, the body does everything it can to promote blood clotting and, ultimately, wound healing. The general term hemostasis refers to the stoppage of bleeding, and it just one of the many factors, others being platelets and thromboxane A2, that are essential for proper wound healing. This lesson details the process of blood coagulation, from the clotting factors to the coagulation cascade.

What is Thrombocytopenia? - Definition, Causes & Treatment

2. What is Thrombocytopenia? - Definition, Causes & Treatment

Thrombocytopenia is a blood disorder characterized by a deficiency in platelet count causing difficulties with blood clotting. Learn how low production, higher rates of destruction, and poor circulation of platelets occurs, and available treatments.

Bleeding Out:  ITP and Wiskott-Aldrich Syndrome

3. Bleeding Out: ITP and Wiskott-Aldrich Syndrome

Wiskott-Aldrich Syndrome and Immune Thrombocytopenic Purpura (ITP) are both bleeding disorders with low platelet counts causing longer bleeds and easier bruising. Learn the causes, and features of platelets in each of these disorders.

What Is Hemophilia? - Symptoms, Genetic Cause & Treatment

4. What Is Hemophilia? - Symptoms, Genetic Cause & Treatment

Different clotting factors can cause blood clots to form incorrectly; this is a bleeding disorder known as hemophilia. Explore more of this disease--including the clotting cascade and clotting factors--and understand the common symptoms and treatments.

Von Willebrand's Disease: Types, Factors, and Treatments

5. Von Willebrand's Disease: Types, Factors, and Treatments

Von Willebrand's Disease is a hereditary bleeding disorder that affects the blood clotting process. Learn about the types, causes, factors, and treatment for Von Willebrand's Disease.

Polycythemia: Definition & Causes

6. Polycythemia: Definition & Causes

Polycythemia is a blood disorder defined by an overabundance of red blood cells in the body. Investigate the different types of polycythemia, such as polycythemia vera and secondary polycythemia, and discover possible causes of the disorder.

Thromboemboli: Definition, Causes & Treatments

7. Thromboemboli: Definition, Causes & Treatments

Thromboemboli is a blood clot that can be caused by injury to a blood vessel or when blood flow is restricted. Understand the definition and causes of thromboembolic and venous thromboembolism, and examine treatments for thromboemboli.

Disseminated Intravascular Coagulation: Definition & Causes

8. Disseminated Intravascular Coagulation: Definition & Causes

Disseminated intravascular coagulation (DIC) is where blood clots are formed in places where there is no need for them. Study the definition and causes of DIC.

Severe Combined Immunodeficiency: Causes, Symptoms & Treatment

9. Severe Combined Immunodeficiency: Causes, Symptoms & Treatment

Severe combined immunodeficiency (SCID) is a potentially life-threatening genetic disorder that inhibits the body's ability to fight infections. Learn about the causes, symptoms, and treatment of SCID, which is a deficiency of B and T cells, which are the two major weapons of the immune system.

Blood Types: ABO System, Red Blood Cell Antigens & Blood Groups

10. Blood Types: ABO System, Red Blood Cell Antigens & Blood Groups

Blood types are determined by antigens found in red blood cells. Learn about the blood types, red blood cell antigens, agglutination, the ABO system, the blood groups, and the definitions of universal donor and universal recipient blood types.

Transfusion and Transplant Reactions

11. Transfusion and Transplant Reactions

Transfusion and transplant reactions occur when the body's immune system rejects blood and organs from another body. Learn about transfusion and transplant reactions, matching donors with recipients, cross matching, tissue typing, and GVHD.

Acquired Immune Deficiencies

12. Acquired Immune Deficiencies

Acquired immune deficiency is when a person contracts a disease that greatly reduces the effectiveness of their immune system. Explore the definition of immune deficiency and the signs of immune deficiencies in this lesson.
