Chapter 11- Blood
Following a major car accident, the patient is brought to the hospital after losing 3 liters of blood. To save the patient's life, the ER medical staff should transfuse what blood type?
O-
The process that occurs after agglutination is known as __________; bursting of RBCs
hemolysis
lymphocytes
produce antibodies which seek out foreign invaders
Neutrophils, eosinophils, and basophils are all __________.
granulocytes
erythrocytes
help carry O2 throughout the bloodstream
The primary function of white blood cells is to
help defend the body against infectious organisms
Which ABO blood type has neither A, B, or Rh antigens?
type O negative
WBC
usually the first to arrive at an injury site; very active phagocytes - attacks and digests bacteria
During blood transfusions, which of the following blood types would NEVER cause an agglutination reaction when introduced into an individual with Type A+ blood?
Type O- blood
osmotic pressure
Which type of pressure is higher for moving fluids back into the capillary?
A condition in which the oxygen-carrying capacity of RBCs is reduced
anemia
platelet
anucleated and a cell fragment
RBC
anucleated and bioconcave
neutrophils
attack bacteria
The function of hemoglobin is to
bind and transport oxygen and carbon dioxide.
capillary
blood vessel where you would find gas exchange
whole blood
combination of plasma, WBCs and RBCs
Erythropoietin is most likely released under which of the following conditions?
during anemia
RBCs - formed element - most numerous, stimulated by erythropoietin
erythrocytes
percentage of whole blood volume occupied by cellular elements
hematocrit
O2 binds to heme group on what molecule?
hemoglobin
WBCs - formed element
leukocytes
WBC
nucleated and spheroid
The three types of formed elements found in blood are _________.
platelets, red blood cells, and white blood cells
eosinophils
reduce inflammation & attacks certain worm parasites
basophils
release histamine and heparin
The primary function of RBCs
to carry gases such as carbon dioxide and oxygen
The formation of red blood cells is called __________.
erythropoiesis
monoctyes
mature into macrophages which eat pathogens
filtration
occurs to move fluid OUT of the capillary and INTO interstitial fluid
osmosis
occurs to move fluids FROM interstitial fluid back INTO capillary
A person's blood type is determined by the
presence or absence of specific surface antigens on the plasma membrane.
The chief difference between plasma and serum involves the
presence/absence of clotting proteins.
