Blood physiology
Here are the summary notes based on the uploaded presentation:
Physiological Aspects of Blood Investigations:
Blood vessels: Transport system for blood.
Composition of blood: Includes cells made in the bone marrow.
Types of Blood Cells:
Erythrocytes (Red blood cells): Oxygen transport.
Platelets (Thrombocytes): Involved in blood clotting.
Basophils, Neutrophils, Monocytes, Eosinophils, Lymphocytes: White blood cells with various roles in immune defense.
Blood Investigations:
Complete Blood Count (CBC): Measures the number and types of cells in the blood (red cells, white cells, platelets).
Haematocrit: Proportion of red blood cells in blood, typically 45% or 0.45.
Differential Blood Count: Breakdown of different types of white blood cells to detect abnormalities.
Blood Groups:
Antigens: Molecules on the surface of cells, recognized by the immune system (e.g., bacteria and viruses have foreign antigens).
Blood Type Antigens: Determine blood group (A, B, AB, O).
Blood Transfusion Compatibility: Dependent on matching blood type antigens and Rhesus antigens (RhD).
