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).
