Blood
Oxygenated blood is _____ while unoxygenated blood is _______ in color
oxygenated - blood is light red
unoxygenated - blood is dark red to purple
The intercellular substance of blood is a fluid called ______
plasma
Cellular elements of blood, which are collectively referred to as formed elements are:
Red blood cells
White blood cells
Platelets
_______ transport oxygen from the lungs and nutrients from the gastrointestinal tract to tissues where they are needed. It also carries carbon dioxide and waste materials to the organs where they are to be disposed of
Blood
In the field of medicine, ______ is the tissue that is most widely used for diagnostic and monitoring purposes
Blood
Blood comprises about ____% of a person’s body weight
8%
Normal pH of blood is _______

a protein that forms fibrous network
Fibrin
If the clot is removed from clotted blood, the straw-colored fluid that remains is called
Serum
is a transparent, yellowish fluid that contains numerous dissolved substances
Plasma
Albumin accounts for ___ % plasma proteins
60%
globulins accounts for ___% plasma proteins
36%
fibrinogen accounts for ___% plasma proteins
4%
is the smallest of the plasma proteins that maintains the colloid osmotic pressure of blood and binds and transports some molecules, notably free fatty acids, some steroid hormones and bilirubin
Albumin
____ and ____ globulins bind and transport substances to various parts of the body
Alpha and Beta globulins
_____ globulins (immunoglobulins) comprise the antibodies of the immune sytem
Gamma globulins
_____ the precursor of fibrin, the protein needed to complete the final step of blood cutting
Fibrinogen
are plasma proteins that transport lipids, which are insoluble in water, from the intestines to the liver and from the liver to the tissues
Lipoproteins
this group of WBC contain specific granules in their cytoplasm
granular leukocytes (granulocytes)
this group of WBC does not contain any granules in their cytoplasm
agranular leukocytes (agranulocytes)
________ method is the prototypical staining technique that used to distinguish the formed elements of blood and cells in the bone marrow from each other under the LM with the use of acid and basic dyes.
Romanowsky method
granulocytes are further classified into three kinds:
- neutrophil
- eosinophil
- basophil
(NEB)
agranulocytes are further classified into two kinds:
- monocyte
- lymphocyte
(ML)
Three types of lymphocytes are:
- T lymphocyte (T cell)
- B lymphocyte (B cell)
- Natural Killer cell (NK cell)
It is one of the parameters used to screen for and measure the extent of anemia
hematocrit
a condition where the oxygen-carrying capacity of blood is decreased
Anemia
are the fewest among the formed elements
WBCs
The average lifespan of RBCs is
120 days
The average lifespan of platelets is between
9-12 days
they oxygen-carrying pigment of the cells
hemoglobin
RBCs are produced in the _________
bone marrow
Immature RBCs are called
reticulocytes
Normal-sized RBCs are called
normocytes
RBCs that are greater than 9 micromillimeter are called
macrocytes
RBCs that are less than 6 micromillimeter are called
microcytes
RBCs form surface of spicules or spines called
echinocytes
Antibodies are also known as
agglutinins
is a substance in which the immune system perceives as foreign to the body and which consequently induces an immune response
Antigen
Persons whose RBCs contain antigen A have type __ blood
Type A blood
Persons whose RBCs contain antigen B have type ___ blood
Type B blood
Persons whose RBCs possess both A and B antigens have type ____ blood
Type AB blood
Persons whose RBCs have neither A or B antigens have type ___ blood
Type O blood
Notes: type A person have anti-B antibodies in their plasma
type B person have anti-A antibodies
type O person have both anti-A and anti-B antibodies
Type AB person have no antibodies
Notes: In the Rh system, people with the Rh antigen on the surface of their RBCs are Rh+ while those that do not have the Rh antigen are classified Rh-
are membrane-bound cell fragments that are often seen in clumps in blood smears
platelets
Platelets are produced by fragmentation of the cytoplasm of giant cells known as
megakaryocytes
defend the body against parasites
Eosinophils
precursor cells of macrophages
monocytes
comprise a family of cells that act as the spherical agents of the body’s immune response
Lymphocyte
True or False: Lymphocytes enlarge when activated.
True
are responsible for humoral immunity
B-cells
are responsible for cell-mediated immunity
T-cells
are cytotoxic cells that play an important role in the body’s inflammatory and immune responses. they destroy tumor cells and cells infected by viruses
NK cells
