What is anemia? Anemia is a condition where blood has an
abnormally low oxygen-carrying capacity,
insufficient to support normal metabolism.
What are the general causes of The causes of anemia include blood loss,
anemia? insufficient RBC production, and excessive RBC
destruction.
What is hemorrhagic anemia? Hemorrhagic anemia is caused by rapid acute
blood loss, such as from a severe wound.
What is chronic hemorrhagic Chronic hemorrhagic anemia is due to slight,
anemia? persistent blood loss, such as from hemorrhoids.
What causes iron deficiency Iron deficiency anemia is caused by low iron
anemia? intake or impaired iron absorption.
What is pernicious anemia? Pernicious anemia is an autoimmune condition
that destroys stomach mucosa, leading to
insufficient RBC production.
, What are hemolytic anemias? Hemolytic anemias occur when RBCs are
destroyed due to incompatible transfusions,
infections, or genetic disorders.
What is hemostasis? Hemostasis is a fast series of reactions to stop
bleeding.
What are the three main steps in 1. Vascular spasm: smooth muscle contracts
hemostasis? causing vasoconstriction. 2. Platelet plug
formation: injury exposes collagen fibers, leading
to platelet adhesion. 3. Coagulation: fibrin forms
a mesh that traps RBCs and platelets to form a
clot.
What are platelets? Platelets are fragments of larger megakaryocytes
that form a temporary plug to seal breaks in
blood vessels.
What are the intrinsic and extrinsic Intrinsic pathway is initiated by less damage to
pathways of blood coagulation? the vessel, is slower, and involves more steps.
Extrinsic pathway is initiated by more damage
and is faster with fewer steps.
What is the shared purpose of the The shared purpose is to activate prothrombin
intrinsic and extrinsic pathways? activator.
What are the shared steps involved 1. Formation of prothrombinase. 2. Conversion of
in Phases 2 and 3 of coagulation? prothrombin to thrombin. 3. Conversion of
fibrinogen to fibrin monomer. 4. Thrombin helps
fibrin become a cross-linked fibrin mesh.
