    Study Notes

    Blood Types and Compatibility

    • Blood type A has A antigens on red blood cells (RBCs) and anti-B antibodies in the plasma. Compatible recipients are A and AB.
    • Blood type AB has both A and B antigens on RBCs and no antibodies in the plasma. It's a universal plasma donor. Compatible donors are A, B, AB, and O.
    • Blood type B has B antigens on RBCs and anti-A antibodies in the plasma. Compatible recipients are B and AB.
    • Blood type O has neither A nor B antigens on RBCs and both anti-A and anti-B antibodies in the plasma. It's a universal RBC donor. Compatible recipients are O and AB.

    White Blood Cell (WBC) Types and Ranking

    • WBCs are classified as granulocytes (Neutrophils, Eosinophils, Basophils) or agranulocytes (Lymphocytes, Monocytes).
    • Ranking WBCs from least to most numerous: Basophils < Eosinophils < Monocytes < Lymphocytes < Neutrophils.

    Formed Elements of Blood

    • Formed elements are erythrocytes (RBCs), leukocytes (WBCs), and thrombocytes (platelets).

    Blood Component Ranking After Centrifugation

    • After centrifugation, blood components separate according to density.
      • Plasma is at the top.
      • Buffy coat (WBCs and platelets) is in the middle.
      • Erythrocytes are at the bottom.

    Blood Circulation and Heart

    • Pulmonary circuit: The circuit from the right ventricle to the lungs.
    • Pericardium: The double-walled sac surrounding the heart.
    • Blood transfusion compatibility depends on blood type and antibodies present.
    • WBCs primarily reside in lymphoid organs (e.g., spleen, lymph nodes).
    • Hemostasis is the process of stopping bleeding involving vasoconstriction, platelet plug formation, and coagulation.
    • Blood functions include oxygen and nutrient transport, waste removal, immune defense, temperature regulation, and pH homeostasis.

    Blood Components and Functions

    • Buffy coat: Contains white blood cells (WBCs) and platelets.
    • Most abundant plasma protein: Albumin.

    Additional Blood Information

    • Agglutination: Occurs when mixing blood types with incompatible antibodies (e.g., Type O blood with anti-A and anti-B sera will not agglutinate). Agglutination occurs when mixing type A blood with anti-A sera.
    • Cells with a large nucleus: Lymphocytes.
    • Most abundant WBC in normal differential count: Neutrophils.
    • The formed element with the highest percentage of blood volume: Erythrocytes (measured as hematocrit).

    • Heart muscle: Myocardium.
    • Vessels carrying oxygen-poor blood from the heart: Pulmonary arteries and vena cava.
      • Space enclosing the heart: Pericardial cavity.
      • Heart pacemaker: Sinoatrial (SA) node.
      • Parts of the heart conduction system: SA node → AV node → Bundle of His → Purkinje fibers.

    Additional Blood Information (continued)

    • Vessels returning blood to the heart: 4 (2 pulmonary veins, 2 vena cavae).
    • Vessels returning oxygenated blood to the heart: 2 pulmonary veins.
    • Vessels returning non-oxygenated blood to the heart: 2 vena cava.
    • Location of greatest blood volume: Veins.
    • Capillaries: Sites of nutrient and gas exchange in the circulatory system.
    • Collection site of venous blood from coronary circulation: Coronary sinus.

    Blood Conditions and Diagnoses

    • Suggestive diagnosis of an abnormally high number of monocytes: Chronic infections, leukemia, or inflammatory conditions.
    • Anti-A and anti-B antibodies develop naturally, not as a result of prior exposure.
    • Blood incompatibility occurs when plasma antibodies attack RBC antigens.
    • Coagulation begins with vascular spasm and ends with platelet plug formation.
    • Organs where most RBCs die: Spleen and liver.
    • Nutrient deficiency causing pernicious anemia: Vitamin B12.
    • Universal RBC donor: O negative.
    • Antigens and antibodies in type B, Rh-positive blood: Antigens: B, Rh. Antibodies: Anti-A.

    Additional WBC Information

    • Least abundant formed element : Basophils.
    • WBCs increasing in response to bacterial infections: Neutrophils.
    • WBCs aiding in defense by secreting histamine and heparin: Basophils.
    • Condition of having WBC count > 10,000 WBCs/µL: Leukocytosis.
    • Largest leukocyte with a kidney-shaped nucleus: Monocytes.
    • Term for abnormal clotting in unbroken vessels: Thrombosis. -Broken clot traveling in bloodstream: Embolism.
    • Location of hematopoietic stem cells: Bone marrow.
