The study of blood cell formation, destruction,
maturation, and number of blood cells which can vary
with disease or infection. [ Ans: ] What is hematology?
Blood, that may be clotted or anticoagulated with EDTA,
heparin, or sodium citrate. [ Ans: ] What is the most
common specimen of hematology?
RBCs or erythrocytes, platelets or thrombocytes (PLT),
WBCs or leukocytes, monocytes, lymphocytes, and
granulocytes which include banded or segmented
neutrophils, basophils, and eosinophils. [ Ans: ] What are
the types of normal blood cells?
Complete blood count. RBCs, WBCs, platelets, hemoglobin,
and hematocrit. [ Ans: ] What is CBC and what does it
count?
Mean cell volume measures the size of RBCs. Mean cell
hemoglobin measures the weight of hemoglobin in RBCs.
Mean cell hemoglobin content measures the average
concentration of hemoglobin within RBCs. MCH and MCHC
are increased with macrocytic anemia and decreased with
microcytic anemia. [ Ans: ] What does MCV stand for?
MCH? MCHC? What causes MCH and MCHC to be increased
or decreased?
,2
It categorizes cells in a 100-cell differential based on their
maturity levels, to determine if a disease or infection is
present. [ Ans: ] What is white cell differential? (diff)
Spleen, liver, thymus, lymph nodes, and bone marrow.
The RES is a network of cells within these tissues that help
with the formation and destruction of RBCs to fight
infection and prevent bleeding, the metabolism of iron to
give to RBCs to carry oxygen through hemaglobin,
inflammation, and immunity. [ Ans: ] What are the organs
of the RES and what is their function?
Bone marrow, found within the cavities of cortical bones
where the trabecular bone is also found. In utero and at
birth, most bones contain red bone marrow. At age 7, sites
of bone marrow begin to decrease and are restricted to
proximal long bones, vertebrate, skull, sternum, ribs, and
pelvis. Adults have 50:50 ratio of red to yellow bone
marrow. [ Ans: ] What is one of the largest organs in the
body and where is it found? Is the site of active bone
marrow always the same?
There are two types of bone marrow. Red that is actively
producing RBCs, and yellow that is inactive, mainly
composed of fat cells. Red bone marrow is composed of
extravascular cords that contain all blood cell lineages,
stem cells, progenitor cells, adventitial cells, and
macrophages. The cords are semi liquid and wedged
between sinuses, supported by trabeculae. [ Ans: ] What
are the types of bone marrow? What is the composition of
red bone marrow?
, 3
Periosteal arteries that wrap around the central vein
supply blood. The periosteal arteries branch out to form
capillaries and sinuses which hook up to larger veins to
return the blood to circulation. [ Ans: ] How does red bone
marrow receive blood supply?
The cells are released as the body needs them. RBCs are
kept at a steady rate. Adventitial cells forming a
discontinous line along the sinus will retract allowing the
RBCs to exit into circulation.
If needed, the yellow bone marrow can convert into red
marrow to help make RBCs. [ Ans: ] How are cells released
from the bone marrow? What are measures the body can
take if RBCs aren't able to be supplied fast enough?
Lymphocytes, plasma cells, and macrophages. They play a
role in producing new lymphocytes, interacting with
antigens and making antibodies, and ridding the blood of
bacteria and debris. [ Ans: ] What do the lymph nodes
encapsulate? What do these do?
Spleen, it functions to act as a filter for blood to remove
old or deformed RBCs from circulation. These RBCs will
either be culled (destroyed entirely) or pitted
(macrophages bite out damaged section). The spleen can
also become a site of RBC production if needed and is also
a holding cell for platelets. [ Ans: ] What is the largest
lymphoid organ? What does it do?
It has a red outer pulp and an inner white pulp. Blood
passes through the red pulp first that has macrophage
