Chapter 19 Flashcards
List three functions of blood
- Transportation (oxygen, nutrients, heat, wastes)
- Regulation (pH, temperature)
- Protection (clots, disease)
List the different types of blood cells
- Red blood cells (erythrocytes)
- White blood cells (leukocytes)
- Platelets
Red blood cells (erythrocytes)
- Transport oxygen from lungs to body cells
2. Deliver carbon dioxide from body cells to the lungs
White blood cells (leukocytes)
Protect the body from invading pathogens and other foreign substances
5 kinds of WBCs:
1. Neutrophils
2. Basophils
3. Eosinophils
4. Monocytes
5. Lymphocytes (T cells, B cells, NK cells)
Platelets

Definition of hematocrit
The percentage of total blood volume occupied by RBCs
What is a typical hematocrit for an adult
-
How would you describe anemia and polycythemia in terms of normal hematocrit
-
What hormone can affect the hematocrit
-
How is whole blood defined
-
What is blood plasma
-
List some characteristics of blood discussed in class
-
What is hemopoiesis (hematopoiesis)
-
What effect does the growth factor (which is a hormone) erythropoietin (EPO) have on blood stem cells in the red bone marrow
-
Discuss molecule hemoglobin produced by erythrocytes (RBC)
-
Discuss steps involved in recycling RBC
-
Discuss how a blood clot is formed
-
Discuss how a blood clot is removed
-
Discuss the condition hemophilia
- Bleeding disorder
- Lacks some clotting factor so blood does not clot, causing excessive bleeding
- Inherited deficiency of clotting in which bleeding may occur spontaneously or after minor trauma
Discuss sickle cell anemia
-
Jaundice
-
Treatment for hemophilia
- Administer missing clotting factors
2. Drug that increases blood clotting factors
