Lab Practical One Flashcards
blood pressure is measured with what
sphygmomanometer
what sounds do you listen to when measuring blood pressure
korotkoff
what is a heart attack also called
myocardial infarcation
what percent of white blood cells are neutrophils
50%
what percent of white blood cells are eosinophils
2-4%
what percent of white blood cells are basophils
less than 1%
what percent of white blood cells are lymphocytes
25%
what percent of white blood cells are monocytes
3-8%
blood has abnormally low oxygen carrying capacity
iron deficiency
why is the lack of iron a problem in iron deficiency
without iron, hemoglobin can’t be produced
this occurs due to mutation in hemoglobin gene
sickle cell anemia
what can sickle cell anemia lead to
acute or chronic complications and potentially death
what is the blood flow through the heart
deoxygenated blood from vena cava-right atrium-tricuspid valve-right ventricle-pulmonary semilunar valve-pulmonary trunk-pulmonary arteries-lungs(gas exchange)-oxygenated blood returns from pulmonary veins-left atrium-bicuspid valve-left ventricle-aortic semilunar valve-aorta-body
this increases in the number or proportion of WBCs in the blood in response to infection
leukocytosis
increase in eosinophill count due to allergic reaction or parasitosis
eosinophillia
high platelet count
thrombocytosis
what is on the surface of red blood cells that allows blood to be classified
glycoproteins(antigens and agglutiongens)
what are glycoproteins accompanied by
antibodies and agglutins
when antibodies react with RBCs bearing different antigens what happens
clumping, agglutination and hemolysis
what antibodies and antigens are present in group A
anti B antibody and A antigen
what antibodies and antigens are present in group B
anti A antibody and B antigen
what antibodies and antigens are present in group AB
no antibodies and A and B antigens
what antibodies and antigens are present in group O
anti A and anti B antibodies and no antigens
another word for agglutinogen
antigen
how much of the average population has positive blood
85%
this refers to the heart beating like a single unit
functional synctium
what are the two types of controlling systems
intrinsic conduction(nodal system) and ANS
alternating surges of pressure in an artery
pulse
what does a normal pulse rate equal
heart rate
where is the pulse strongest
common carotid artery
when does the pulse occur
with each contraction and relaxation of left ventricle
pressure blood exerts against the blood vessel walls
blood pressure
measure in arteries
blood pressure
