Module 7: Blood and Blood Vessels
(Anatomy 337 UW Madison) Exam|
111 Q’s and A’s |Distinction Graded
What are the components of blood? - -Erythrocytes (RBCs), Leukocytes, and
Platelets
- What does plasma (the extracellular matrix) do for the blood? What does it
do for the formed elements? - -It makes the blood unique among connective
tissues because it is fluid.
Plasma suspends the formed elements and enables them to circulate
throughout the body within the cardiovascular system.
- What are erythrocytes (RBCs) responsible for? - -transport oxygen, and
some carbon dioxide.
- What are leukocytes (white blood cells) responsible for? - -responsible for
defending against potentially harmful microorganisms or molecules. Helps
the immune system
- Are platelets cells? What are platelets responsible for? - -No, Platelets are
cell fragments. Platelets are involved in blood clotting, limit blood loss
- What is the main function of blood? - -The primary function of blood is to
deliver oxygen and nutrients to and remove wastes from body. Defense and
maintenance of homeostasis.
- True or False. All formed elements arise from epithelial cells of the yellow
bone marrow. - -FALSE. All formed elements arise from STEM CELLS of the
RED bone marrow.
- Hematopoiesis results in what kind of cells? - -Lymphoid stem cells and
Myeloid stem cells
- What do lymphoid stem cells give rise to? - -Lymphoid stem cells give rise
to a class of leukocytes known as lymphocytes, including the various T cells,
B cells, and natural killer (NK) cells, all of which function in immunity.
- Where do T cells mature? Where do B cells mature? - -Thymus, bone
marrow
, - What do myeloid stem cells give rise to? - -Myeloid stem cells give rise to
all the other formed elements, including the erythrocytes; megakaryocytes
that produce platelets; and a myeloblast lineage that gives rise to monocytes
and three forms of granular leukocytes: neutrophils, eosinophils, and
basophils.
- What test measures the amount of RBCs in our blood?
What is the buffy coat made of?
What percentage of our blood is plasma and what percentage of our blood is
formed elements? - -Hematocrit
Buffy coat: white blood cells, platelets
55% plasma, 45% erythrocytes (formed elements)
- True or False. Erythrocytes leaving blood vessels is normal. - -FALSE.
Erythrocytes leaving blood vessels is ABNORMAL.
- Hemoglobin is a large molecule made up of _______ and ______. These
globin molecules are bound to a red pigment molecule called ______, which
contains an ion of ________. - -proteins, iron, heme, iron
- Type A blood:
What antigens?
What antibodies? - -Has A antigens
preformed anti-B antibodies
- Type B blood:
What antigens?
What antibodies? - -Has B antigens
preformed anti-A antibodies
- Type AB blood:
What antigens?
What antibodies? - -Has both A and B antigens
no antibodies
- Type O blood:
What antigens?
What antibodies? - -Has neither A or B antigens, anti-A antigens and anti-B
antigens circulate in plasma.
- True or False. In contrast to the ABO group antibodies, which are
preformed, antibodies to the Rh antigen are produced only in Rh− individuals
after exposure to the antigen. - -True
- What are neutrophils? - -Neutrophils are rapid responders to the site of
infection and are efficient phagocytes with a preference for bacteria.
