Anatomy Review for LPN

Introduction

  • Instructor: Samira Seddiki
  • Material Focus: Oxygen-carrying blood cells, types of blood cells, blood conditions, and heart structure.

Blood Cells

Oxygen-Carrying Blood Cell
  • Erythrocyte: The correct answer; it is an oxygen-carrying blood cell.
Characteristics of Blood Cells
  • Granulocyte: Characteristics include being granulocytic, phagocytic, and motile.
    • Correct answer: Neutrophil.
Reticulocyte Definition
  • Reticulocyte: Described as an immature erythrocyte.
Jaundice and Blood Cells
  • Jaundice: Rapid breakdown of red blood cells causes jaundice.
Thrombocytopenia
  • Definition: Refers to a deficiency of platelets.
  • Causes: Myelosuppression can lead to thrombocytopenia.
  • Accompanying Conditions: May be accompanied by aplastic anemia and granulocytopenia.

Heme and Hemolysis

Heme Composition
  • Heme contains iron.
Results of Hemolysis
  • Effects of Hemolysis:
    • Causes hyperbilirubinemia.
Bilirubin
  • Bilirubin Breakdown: It is a breakdown product of red blood cells.
Erythrocyte Count Implications
  • Decrease in erythrocytes may cause anemia.

Leukocyte Conditions

Leukocytosis and Leukopenia
  • Definitions:
    • Leukocytosis: Increased numbers of white blood cells.
    • Leukopenia: Decreased numbers of white blood cells.
    • Both conditions represent abnormal numbers of white blood cells.
    • Possible results from myelosuppression.

Blood pH

Normal Blood pH Range
  • Normal pH of blood is between 7.35 to 7.45.

Blood Cell Origin
