Blood Physiology Quiz

Anaemia is a condition characterized by a deficiency of red blood cells or hemoglobin in the blood. It can be classified based on the size of red blood cells into microcytic, normocytic, and macrocytic anaemia. Common causes of anaemia in Bangladesh include nutritional deficiencies (iron, folate, vitamin B12), infections (such as malaria), and genetic disorders.

Blood is a bodily fluid that carries nutrients, oxygen, and waste products throughout the body. Its composition includes red blood cells (erythrocytes) for oxygen transport, white blood cells (leukocytes) for immune response, platelets for blood clotting, and plasma for carrying nutrients, hormones, and waste products.

Blood group is a classification of blood based on the presence or absence of specific antigens on the surface of red blood cells. Landsteiner's law states that an individual will agglutinate with the antibodies of any blood group other than their own. Hazards of blood transfusion include transfusion reactions, transmission of infections (such as HIV, hepatitis), and potential for iron overload.
