Study Notes

Functions of Blood

  • Blood transports oxygen, nutrients, hormones, and waste products throughout the body.
  • Regulates body temperature, pH balance, and fluid balance.
  • Protects the body by containing white blood cells for defense against pathogens and platelets for blood clotting.

Components of Whole Blood

  • Plasma: the liquid portion of blood, consisting of water, electrolytes, proteins, and other solutes.
  • Formed Elements: red blood cells, white blood cells, and platelets.

Components of Plasma

  • Water: the majority component, serving as a solvent for other substances.
  • Proteins: include albumin, globulins, and fibrinogen.
  • Electrolytes: include sodium, potassium, chloride, calcium, and bicarbonate.
  • Nutrients: include glucose, amino acids, lipids, and vitamins.
  • Waste Products: include urea, creatinine, and bilirubin.
  • Hormones: chemical messengers.
  • Gases: include oxygen and carbon dioxide.

Plasma and Proteins

  • Albumins: maintain osmotic pressure and are produced by the liver.
  • Globulins: include immunoglobulins (antibodies).
  • Fibrinogen: a glycoprotein that aids in blood clotting by forming fibrin.

Serum vs. Plasma

  • Plasma: contains clotting factors.
  • Serum: plasma minus clotting factors, collected after blood clots.

Formed Elements of Blood

  • Red Blood Cells (Erythrocytes): biconcave discs that transport oxygen and have a lifespan of 120 days.
  • Platelets (Thrombocytes): fragments from megakaryocytes, essential for clotting.
  • White Blood Cells (Leukocytes): involved in immune response.

Oxygenated vs. Deoxygenated Blood

  • Oxygenated Blood: high oxygen, bright red, found in systemic arteries and pulmonary veins.
  • Deoxygenated Blood: low oxygen, dark red or bluish, found in systemic veins and pulmonary arteries.

Blood Conditions

  • Anemia: low red blood cell count.
  • Polycythemia: high red blood cell count.

Erythropoiesis

  • Production of red blood cells in bone marrow, regulated by erythropoietin.

Hematocrit

  • Proportion of red blood cells in blood, higher in males.
  • Assessed in a complete blood count (CBC).

Leukocytes (White Blood Cells)

  • Neutrophils: first responders, engulf bacteria.
  • Lymphocytes: involved in adaptive immune response.
  • Types of Lymphocytes: B cells, T cells, NK cells, Monocytes, Eosinophils, Basophils.

CBC and CBC Diff

  • CBC: measures red blood cells, white blood cells, and platelets.
  • CBC Diff: breaks down white blood cell types, used to diagnose and monitor health conditions.

Platelets (Thrombocytes)

  • Morphology: small, disc-shaped, no nucleus.
  • Precursor Cell: megakaryocytes.
  • Function: blood clotting, forming plugs, and releasing clotting chemicals.
  • Thrombopoietin: hormone regulating platelet production.

Hematopoiesis

  • Location: bone marrow.
  • Hematopoietic Stem Cells: multipotent cells producing all blood cell types.

Hemostasis

  • Vascular Spasm: immediate vessel constriction post-injury.
  • Platelet Plug: platelets adhere to the injury site, forming a plug.
  • Coagulation: fibrin formation stabilizes the plug into a clot.

Hemorrhage

  • Excessive blood loss from the circulatory system.

Fibrinolysis

  • Clot breakdown by plasmin to restore normal blood flow.

Blood Group Classification

  • ABO classification: antigen found on the surface of red blood cells.
  • ABO classification: antibody found in the plasma (or serum) of the blood.
  • Rh classification: antigen found on the surface of red blood cells.
  • Rh classification: antibody found in the plasma (or serum) of the blood.

Universal Donor Blood

  • Type O negative blood is considered the universal donor type.
