Review of anatomy and physiology of blood products.
Review of Anatomy and Physiology of Blood Products
Blood is a vital connective tissue that circulates through the cardiovascular system, delivering oxygen and nutrients to tissues, removing waste products, and playing a critical role in immune defense and homeostasis.
Components of Blood
Blood is composed of two main parts:
Plasma (55% of blood volume):
Composition:
Water: 90–92%; serves as a solvent and temperature regulator.
Proteins: 7–8% (albumin, globulins, fibrinogen).
Other Solutes: Electrolytes, glucose, hormones, enzymes, gases (O2, CO2).
Functions:
Transport of nutrients, hormones, and waste products.
Regulation of fluid and electrolyte balance.
Maintenance of blood pressure and acid-base balance.
Lymphoid Lineage: B cells, T cells, natural killer (NK) cells.
Blood Groups and Typing
ABO Blood Group System:
Determined by the presence of A and/or B antigens on RBCs.
Blood Types:
Type A: A antigen, anti-B antibodies.
Type B: B antigen, anti-A antibodies.
Type AB: A and B antigens, no antibodies (universal recipient).
Type O: No antigens, anti-A and anti-B antibodies (universal donor).
Rh Factor:
Positive (+) if Rh antigen is present; negative (-) if absent.
Rh incompatibility can cause hemolytic disease of the newborn.
Functions of Blood
Transportation:
Oxygen from lungs to tissues.
Nutrients from digestive tract to cells.
Waste products to kidneys and liver for excretion.
Hormones from endocrine glands to target tissues.
Regulation:
Maintains body temperature through heat distribution.
Regulates pH (buffer systems) and fluid-electrolyte balance.
Protection:
Prevents blood loss through clotting mechanisms.
Protects against infections via WBCs and antibodies.
Applied Relevance in Nursing
Blood Transfusions:
Ensure compatibility of ABO and Rh blood groups.
Monitor for transfusion reactions (e.g., fever, chills, hemolysis).
Monitoring Hematologic Conditions:
Assess RBCs in anemia, WBCs in infections, platelets in bleeding disorders.
Patient Education:
Teach about dietary needs for hematopoiesis (iron, B12, folic acid).
Educate on the importance of regular monitoring in chronic blood disorders.
Management of Blood Disorders:
Administer medications (e.g., erythropoietin, anticoagulants).
Provide supportive care for symptoms like fatigue or bleeding.
Summary
The anatomy and physiology of blood products are crucial for understanding their roles in oxygen transport, immune defense, and clotting. Nurses play a vital role in monitoring and managing conditions affecting blood components, ensuring effective patient care and education.
