Functions & Properties
The percentage of total blood volume occupied by red blood cells
The hematocrit
RBC formation
erythropoiesis
Platelets are disc-shaped cell fragments that splinter from this cell type
megakaryocytes
Three stages of hemostasis
vascular spasm, platelet plug formation, and blood clotting
Before blood is transfused, a recipient’s blood is typed and then _________________ to potential donor blood
cross-matched
The formed elements in blood
red blood cells (erythrocytes), white blood cells (leukocytes), and platelets
The general function of WBCs
to combat inflammation and infection
This procedure involve removal of red bone marrow as a source of stem cells from the iliac crest.
Bone marrow transplants
This is a network of insoluble protein fibers (fibrin) in which formed elements of blood are trapped
A clot
individuals whose RBCs have Rh antigens are classified as __________________
Rh+
Blood pH
7.35–7.45
The function of the hemoglobin in red blood cells
to transport oxygen and some carbon dioxide
Platelets help stop blood loss from damaged blood vessels by forming this
a platelet plug
The chemicals involved in clotting are known as this
clotting (coagulation) factors
This disease can occur when an Rh+ mother is pregnant with an Rh? fetus
Hemolytic disease of the newborn (HDN)
Blood volume
4–6 liters
Types of WBCs
granulocytes (neutrophils, eosinophils, and basophils) and agranulocytes (lymphocytes and monocytes).
in this procedure stem cells from the placenta are removed from the umbilical cord
cord-blood transplant
This stage of hemostais involves a cascade of reactions that may be divided into three stages: formation of prothrombinase, conversion of prothrombin into thrombin, and conversion of soluble fibrinogen into insoluble fibrin
Blood clotting
This classification system sees the presence or absence of antigens on the surface of RBCs, determining blood types
the ABO blood group
% blood plasma
55%
Average Life of RBCs
120 days
Normal blood contains __________________ platelets/[1]L
150,000–400,000
Clotting in an unbroken blood vessel is called this
thrombosis
blood groups are genetically determined and based on this response
antigen–antibody responses
