Blood Disorders: Anemia - Chapter Summary and Learning Objectives

This chapter on anemia can introduce you to the causes of a disease that inhibits red blood cells' ability to transport oxygen. View the lessons included here to find out what a Coombs test is for, examine the uses of blood transfusions and identify affected areas of the body. By the end of this chapter, you should be able to do the following:

  • Identify the functions of red and white blood cells, platelets and hemoglobin
  • Describe the various characteristics, classifications and types of anemia
  • Explain anemia's clinical signs and treatment options
  • Discuss the epidemiology of anemia

Video Objective
Functions of Red Blood Cells, White Blood Cells & Platelets Outlines the role of blood connective tissue in protecting the body from disease and transporting carbon dioxide, oxygen and nutrients.
Rh Blood Group, Rh Factor & Erythroblastosis Fetalis Describes the Rh antigen, the formation of anti-Rh antibodies and the treatment given to prevent erythroblastosis fetalis.
Anemia: Types and Causes Details the function of red blood cells and hemoglobin and provides examples of hemorrhagic, aplastic and pernicious anemia.
Anemia: Classification of Different Types Explains anemia classifications - including normocytic, microcytic, macrocytic, hypochromic and normochromic - and discusses their top causes.
Hemolytic Anemia: Signs and Treatment Distinguishes between hereditary and acquired causes of hemolytic anemias. Hemolysis is also discussed.
Types of Hemolytic Anemia Describes intravascular and extravascular signs of hemolytic anemia as well as treatment options in acute and chronic cases.
Immune Hemolytic Anemia: Causes & Treatment Options Discusses the causes of immune mediated hemolytic anemia and details clinical signs related to hematuria, intravascular hemolysis and extravascular hemolysis. Treatment methods are also covered.
Sickle Cell Anemia: Affected Locations, Signs & Treatments Outlines the locations affected by sickle cell anemia along with the epidemiology, signs and treatments options.
Thalassemia: Causes, Types, and Treatments Explains the epidemiology of thalassemia as well as signs, affected locations and treatments.
Hereditary Spherocytosis: Causes and Symptoms Describes characteristics of hereditary spherocytosis, including splenomegaly, jaundice, Howell-Jolly bodies and spherocytes.

Functions of Red Blood Cells, White Blood Cells & Platelets

1. Functions of Red Blood Cells, White Blood Cells & Platelets

Blood is a connective tissue vital to our body's survival. In this lesson, we will explore the three functions of blood by delving into red blood cells, white blood cells and platelets - the three individual components that make up blood as a whole.

Rh Blood Group, Rh Factor & Erythroblastosis Fetalis

2. Rh Blood Group, Rh Factor & Erythroblastosis Fetalis

Rh factor is a red blood cell antigen found in most people. Those with Rh factor are Rh positive, while those without are Rh negative. In this lesson you will learn about Rh blood compatibility and its importance during pregnancy.

Anemia: Types and Causes

3. Anemia: Types and Causes

Your red blood cells have a unique design that differentiates them from all other cells. This unique design makes them exceptional oxygen carriers. But if this ability to carry oxygen is compromised, the result is a form of anemia, such as pernicious anemia, aplastic anemia or sickle cell anemia.

Anemia: Classification of Different Types

4. Anemia: Classification of Different Types

Anemia is associated with a decrease in red blood cells, or hemoglobin concentration. Ways of classifying anemia depend on the size and hemoglobin content of the red blood cells (morphological) or the mechanism (pathophysiological).

Types of Hemolytic Anemia

5. Types of Hemolytic Anemia

Hemolytic anemia is anemia that results from the destruction of red blood cells. It can be inherited or acquired. Learn about hereditary conditions that cause hemolytic anemia as well as the types of acquired hemolytic anemias.

Hemolytic Anemia: Signs and Treatment

6. Hemolytic Anemia: Signs and Treatment

In hemolytic anemia, red blood cells are destroyed faster than they can be replaced. Typical signs of anemia may be present as well as jaundice and upper abdominal pain. Treatment may include corticosteroids, surgery or a blood transfusion.

Immune Hemolytic Anemia: Causes & Treatment Options

7. Immune Hemolytic Anemia: Causes & Treatment Options

Immune hemolytic anemia is a type of anemia that results due to the destruction of red blood cells by the body's immune system. Learn about the different types (Autoimmune, Alloimmune and Drug-Induced), what causes them and how they are treated.

Sickle Cell Anemia: Affected Locations, Signs & Treatments

8. Sickle Cell Anemia: Affected Locations, Signs & Treatments

Sickle cell anemia is an inherited anemia in which red blood cells are sickle-shaped due to an abnormality in their hemoglobin. Learn who is at risk of this disorder, why symptoms such as pain and fatigue occur and how the condition is treated.

Thalassemia: Causes, Types, and Treatments

9. Thalassemia: Causes, Types, and Treatments

Thalassemia is an inherited blood disorder associated with an abnormal production of hemoglobin. It results in symptoms of anemia and exists as two main types: alpha and beta. Learn about the different types of thalassemia and how they are treated.

Hereditary Spherocytosis: Causes and Symptoms

10. Hereditary Spherocytosis: Causes and Symptoms

Hereditary spherocytosis is an inherited type of hemolytic anemia in which the red blood cells take on a spherical shape. Learn about the cause and symptoms associated with hereditary spherocytosis.
