a & P chapter 19 blood
________ are large phagocytic white cells that spend most of their time outside the blood as fixed and free phagocytic cells.
Monocytes
Which of these descriptions best matches the term T lymphocytes?
They are responsible for cell-mediated immunity
The process of fibrinolysis
dissolves clots.
White blood cells that are increased in allergic individuals are the
eosinophils.
The process of red blood cell production is called
erythropoiesis.
The waste product bilirubin is produced from
heme molecules plus iron.
More than 95 percent of the protein in a red blood cell is
hemoglobin.
Platelets are pinched off from giant multinucleated cells in the bone marrow called
megakaryocytes.
. The most numerous white blood cells in peripheral circulation are the
neutrophils.
A person's blood type is determined largely by the
presence of specific glycoproteins on the cell membrane.
Which of these descriptions best matches the term B lymphocytes?
produce antibodies in response to antigens
In adults, erythropoiesis exclusively takes place in
red bone marrow.
Aged and damaged erythrocytes are broken down by the
spleen, liver, and bone marrow.
In adults, red bone marrow is located in the
sternum and ribs and iliac crest, body of vertebrae only
________ are immature erythrocytes that are present in the circulation.
. Reticulocytes
Erythropoiesis is stimulated when
. both oxygen levels in the blood decrease and blood flow to the kidney declines.
The chief differences between plasma and interstitial fluid involves the
. concentration of proteins.
Red blood cell production is regulated by the hormone
. erythropoietin.
Most of the iron that is removed from degraded hemoglobin is
. recycled to the red bone marrow.
All the circulating red blood cells originate in the
. red bone marrow.
Granulocytes form in
. red bone marrow.
The conversion of fibrinogen to fibrin is catalyzed by the enzyme
. thrombin.
The most abundant component of plasma is
. water.
The average lifespan of a red blood cell is
4 months.
Which of the following is a function of the blood?
a. transport of nutrients and wastes b. transport of body heat c. transport of gases d. defense against toxins and pathogens e. all of these
The most abundant proteins in blood plasma are
albumins.
Platelets are
cytoplasmic fragments of large cells.
White blood cells that release histamine at the site of an injury are
basophils.
The function of red blood cells is to
both carry carbon dioxide from the cells to the lungs and carry oxygen from the lungs to the body's cells
The function of hemoglobin is to
carry oxygen and carry carbon dioxide only
Most of the protein factors that are required for clotting are synthesized by
the liver.
Which of the following vitamins is needed for the formation of clotting factors?
vitamin K
The combination of plasma and formed elements is called
whole blood.
