Which blood component primarily transports oxygen to tissues?
Red blood cells
White blood cells
Platelets
Plasma
Red blood cells contain hemoglobin, a protein that binds and carries oxygen from the lungs to body tissues. Their biconcave shape increases surface area for efficient gas exchange.
What is the primary function of platelets in blood?
Clot formation
Oxygen transport
Antibody production
Hormone delivery
Platelets aggregate at sites of vessel injury and release factors that initiate the blood clotting cascade. This process prevents excessive bleeding and starts tissue repair.
Which plasma protein is most important for maintaining colloid osmotic pressure?
Albumin
Hemoglobin
Fibrinogen
Myoglobin
Albumin is the most abundant plasma protein and exerts oncotic pressure that helps retain fluid in the circulatory system. It also transports various substances including hormones and drugs.
Which white blood cell type is the first responder to bacterial infection and performs phagocytosis?
Neutrophil
Erythrocyte
Basophil
Platelet
Neutrophils are the most abundant leukocytes and migrate rapidly to infection sites where they engulf and destroy bacteria. Their short lifespan and rapid turnover support acute inflammatory responses.
What is the liquid component of blood called when clotting factors are still present?
Plasma
Serum
Lymph
Cytosol
Plasma is the liquid portion of blood containing clotting factors, electrolytes, nutrients, and proteins. Serum is plasma minus fibrinogen and other clotting proteins after coagulation.
A high hematocrit value indicates which condition?
Increased proportion of red blood cells
Decreased plasma volume
Elevated white blood cell count
Low platelet count
Hematocrit measures the percentage of blood volume occupied by red blood cells. A high hematocrit reflects an increased RBC proportion relative to plasma.
Which white blood cell is responsible for producing antibodies?
B lymphocyte
T lymphocyte
Neutrophil
Monocyte
B lymphocytes differentiate into plasma cells that synthesize and secrete antibodies specific to antigens. This adaptive immune response is critical for long-term immunity.
Fibrinogen is converted to fibrin by which enzyme during coagulation?
Thrombin
Plasmin
Prothrombin
Factor VIII
Thrombin cleaves fibrinogen into fibrin monomers that polymerize to form a stable clot. Plasmin later degrades fibrin during clot resolution.
Which granulocyte releases histamine and mediators in allergic reactions?
Basophil
Eosinophil
Neutrophil
Monocyte
Basophils contain granules rich in histamine and heparin that are released during hypersensitivity responses. They play a role in inflammation and allergic reactions.
Which laboratory test primarily assesses platelet function?
Bleeding time
Prothrombin time
Activated partial thromboplastin time
Platelet count
Bleeding time measures how long it takes for a standardized skin incision to stop bleeding, reflecting platelet adhesion and aggregation. PT and aPTT assess coagulation factor pathways.
An elevated erythrocyte sedimentation rate (ESR) is most influenced by which plasma protein?
Fibrinogen
Albumin
Transferrin
Hemoglobin
Fibrinogen increases the aggregation of red blood cells, causing them to settle faster in a test tube. ESR is a nonspecific marker of inflammation and acute phase response.
Which cell type differentiates into macrophages in tissues?
Monocyte
Lymphocyte
Erythrocyte
Neutrophil
Monocytes exit the bloodstream and differentiate into macrophages in tissues where they phagocytose pathogens and debris. Macrophages also present antigens to lymphocytes.
What term describes variation in red blood cell size?
Anisocytosis
Poikilocytosis
Spherocytosis
Macrocytosis
Anisocytosis refers to a range of RBC sizes seen on a blood smear, often indicating anemia or other hematologic disorders. Poikilocytosis describes variation in cell shape.
Which electrolyte is essential as a cofactor in multiple steps of the coagulation cascade?
Calcium
Sodium
Potassium
Chloride
Calcium ions (factor IV) are required for the activation of various clotting factors and the conversion of prothrombin to thrombin. It bridges negatively charged sites on proteins.
Which factor initiates the intrinsic pathway of coagulation?
Factor XII
Factor VII
Tissue factor
Factor X
Factor XII (Hageman factor) is activated by contact with negatively charged surfaces, triggering the intrinsic coagulation cascade. Factor VII and tissue factor initiate the extrinsic pathway.
In disseminated intravascular coagulation (DIC), which laboratory findings are typical?
Prolonged PT and aPTT with decreased fibrinogen
Shortened PT and aPTT
Elevated platelet count
Increased fibrinogen levels
DIC consumes clotting factors and platelets, prolonging both PT and aPTT and reducing fibrinogen due to widespread fibrin deposition. This leads to both bleeding and microthrombosis.
Thrombopoietin, the main regulator of platelet production, is primarily produced by which organ?
Liver
Bone marrow
Spleen
Kidney
The liver synthesizes thrombopoietin, which stimulates megakaryocyte maturation and platelet production in the bone marrow. The kidney contributes minimally to its production.
In liver cirrhosis, deficiency of which plasma protein most directly contributes to a bleeding tendency?
Prothrombin
Albumin
Transferrin
Hemoglobin
Prothrombin (factor II) is synthesized in the liver and is essential for thrombin generation and clot formation. Cirrhotic patients have decreased levels, leading to coagulopathy.
During acute inflammation, neutrophil function is enhanced primarily by which change?
Increased chemotaxis
Decreased adhesion
Reduced phagocytosis
Lower oxidative burst
Acute inflammatory mediators increase neutrophil chemotaxis toward the injury site. This directed migration enhances their ability to reach and eliminate pathogens.
Factor V Leiden mutation leads to hypercoagulability by making Factor V resistant to inactivation by which protein?
Protein C
Protein S
Antithrombin
Plasmin
Factor V Leiden resists cleavage by activated Protein C, impairing downregulation of the coagulation cascade. This resistance increases the risk of thrombosis.
