#1
Which blood cell is responsible for oxygen transport?
Red blood cell
ExplanationRed blood cells, containing hemoglobin, transport oxygen from the lungs to the rest of the body.
#2
What is the primary function of white blood cells?
Fighting infections
ExplanationWhite blood cells play a key role in the immune system, combating infections and foreign invaders.
#3
Which disorder is characterized by a deficiency of red blood cells or hemoglobin?
Anemia
ExplanationAnemia is a condition marked by a lack of red blood cells or insufficient hemoglobin, leading to reduced oxygen-carrying capacity.
#4
What is the most common type of white blood cell in the human body?
Neutrophil
ExplanationNeutrophils are the most abundant white blood cells and are crucial for the body's defense against bacterial infections.
#5
What is the term for a group of blood disorders that affect the bone marrow and blood cells?
Myeloproliferative neoplasms
ExplanationMyeloproliferative neoplasms are a collection of disorders where bone marrow produces too many blood cells.
#6
Which blood disorder is characterized by abnormal, crescent-shaped red blood cells?
Sickle cell anemia
ExplanationSickle cell anemia is marked by the presence of deformed, crescent-shaped red blood cells, leading to various health issues.
#7
Which white blood cells play a crucial role in the immune response and antibody production?
Lymphocyte
ExplanationLymphocytes are central to the immune system, contributing to antibody production and immune response.
#8
Which blood cell is crucial for blood clotting?
Platelet
ExplanationPlatelets are essential for the formation of blood clots, preventing excessive bleeding.
#9
In which type of anemia does the body have difficulty absorbing vitamin B12?
Pernicious anemia
ExplanationPernicious anemia results from a lack of vitamin B12 absorption, impacting red blood cell production.
#10
What is the main characteristic of Hemophilia?
Impaired blood clotting
ExplanationHemophilia is characterized by a deficiency in clotting factors, leading to impaired blood clotting.
#11
Which blood disorder is characterized by a deficiency of clotting factors in the blood?
Hemophilia
ExplanationHemophilia results from insufficient clotting factors, causing difficulties in blood clotting.
#12
Which blood cell disorder is associated with a rapid and uncontrolled production of abnormal white blood cells?
