Study Notes
Blood Composition
- Plasma is the liquid portion, containing red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
Leukocytes
- Leukopenia: Characterized by an unusually low white blood cell count; leads to prolonged illness.
- Leukocytosis: Indicated by an abnormally high white blood cell count; suggests a significant underlying issue.
-
Types of WBCs:
- Neutrophils: The most prevalent type of white blood cell.
- Eosinophils: Typically involved in allergic responses.
- Basophils: Function as natural blood thinners.
Lymph Nodes
- Act as filters, trapping viruses and allowing white blood cells to effectively eliminate them.
Phlebitis & Thrombophlebitis
- Phlebitis: Inflammation of a vein characterized by smoothness and visible striations.
- Thrombophlebitis: Inflammation caused by a thrombus, resulting in chunkier coagulation and localized blood pooling.
Coagulation
- Essential for stopping bleeding; visible bruising occurs as blood coagulates, forming a star-like pattern.
Tonsils
- Three types of tonsils can be observed when the mouth is open:
- Palatine (top): Only visible through the mouth.
- Pharyngeal (sides).
ABO Blood Group
- Blood types determined by antigens and antibodies:
- Type A: A antigen present, with B antibody in plasma.
- Type B: B antigen present, with A antibody in plasma.
- Type AB: Both A and B antigens present, no antibodies in plasma, making AB the universal recipient.
- Type O: No antigens, but has both A and B antibodies in plasma, making O the universal donor.
- Administration of incompatible blood types (e.g., A type given to A individuals) can trigger the production of anti-A and anti-B antibodies, leading to blood clots.
Red Blood Cell Disorder: Erythropenia (Anemia)
- Defined by a low or abnormal red blood cell count, resulting in fatigue, weakness, fainting, and headaches.
- Symptoms include tachycardia and tachypnea due to insufficient RBCs.
Deficiency Anemia
- Pernicious Anemia: Caused by a deficiency in Vitamin B12; treated with B12 injections.
- Folate Deficiency Anemia: Results from a deficit in Vitamin B9; treated with B9 supplements.
- Common reasons include alcoholism, pregnancies, and malnutrition.
- Iron Deficiency Anemia: Occurs due to inadequate iron levels; oral iron supplements can be prescribed, but gastrointestinal side effects may occur. Dietary changes might be necessary for better intake.
Charts on Anemia
- Distinctions based on cell characteristics:
-
Iron Deficiency Anemia:
- Hypochromic (lighter) RBCs present as smaller cells.
- Microcytic classification noted.
-
Pernicious Anemia:
- Defined by large, macrocytic cells with altered color.
-
Iron Deficiency Anemia:
