Blood Flashcards
Erythropoietin
EPO
hormone produced primarily by the kidneys in response to low oxygen levels in the blood (hypoxia)
Erythrocytes
Red blood cells
Leukocytes
White blood cells
Thrombin
protein enzyme that plays a key role in blood clotting
converts fibrinogen to fibrin
Fibrin
a protein that helps form blood clots, stop bleeding, and heal wounds.
Hemolysis
process when red blood cells break down and release their contents into the surrounding fluid.
Hemoglobin
protein in red blood cells that carries oxygen from the lungs to the body’s tissues and organs
Coagulation
the process of blood changing from a liquid to a gel to form a clot
Agglutination
clumping of red blood cells
Antigen
Carbohydrate groups on the surfaces of erythrocytes determine blood type
Antibody
protein produced by the body’s immune system when it detects harmful substances, called antigens
Granulocytes
neutrophils
eosiophils
basophils
has granules in their cytoplasm
agranulocytes
monoctyes
lymphocytes
lacks granules in their cytoplasm
Erythropoiesis
The process of red blood cell production
Neutrophils
wbc
most common type of leukocyte
Lymphocytes
wbc
produce antibodies
T cells, B cells
Monocytes
wbc
first responders of the immune system
Eosinophils
wbc
help fight infections and allergens
bi lobed nucleus, large granules
Basophils
wbc
fight parasitic worms.,
release heparin
Formed elements
erythrocytes, leukocytes, thrombocytes
Hematocrit
Hemostasis
The stoppage of bleeding
ABO blood group system
classification system for human blood that identifies four main blood types: A, B, AB, and O.
Rh factor
a protein found on red blood cells (RBCs) that determines if a person’s blood is Rh-positive or Rh-negative.
Plasma
liquid component of blood that carries nutrients, waste, and blood cells throughout the body
Platelets
cell fragments in the blood that help stop bleeding and form clots
thrombocytes
calcium ions
necessary for both the intrinsic and extrinsic pathways to the coagulation cascade
hematopoietic stem cell
gives rise to all formed elements
