|
|
define the way blood flows - through what blood vessels |
heart -> aorta/ pulmary artery -> smaller arteries -> arterioles -> capillaries -> venues -> veins |
|
|
describe arteries |
thick walls pulse no valves high bp aways from heart medium lumen |
|
|
describe veins |
thin towards the heart low bp valves no pulse large lumen |
|
|
describe capillaries |
thin and small carry blood to tissues no pulse small lumen |
|
|
what does the lymphatic system do and what are its characteristics |
carries lymph around the body no pulse |
|
|
describe lymph |
clear yellow fluid has blood plasma without plasma proteins |
|
|

what measures a blood pressure |
sphygmomanometer |
|
|
define systole |
blood pressure in the arteries when the ventricles contract |
|
|
define diastole |
blood pressure in arteries when the ventricles relax |
|
|
define hypertension |
high blood pressure |
|
|
what measures heart beat electrical activity |
electrocardiogram |
|
|
what does the prt stand for |

|
|
what percent of whole blood is each component |
55% plasma 45% red blood cells 21% leucocytes |
|
|
what are lymphocytes |
B and T cells |
|
|
what are the types of B cells |
memory and plasma |
|
|
what are the types of T cells |
memory, suppressor, killer, helper |
|
|
what are monocytes |
macrophages |
|
|
what is a macrophage |
eats all the things that the killer T cells tie up through phagocytosis |
|
|
where are the B and T cells made |
in the bone marrow and then the T cells mature in the thymus |
|
|
what antibodies does blood type A have |
B |
|
|
what antibodies does blood type B have |
A |
|
|
what antibodies does blood type O have |
A and B |
|
|
what antibodies does blood type AB have |
none |
|
|
what does antibodies attack |
antigens |
|
|
what is the difference between antibodies and antiserum |
antiserum is man made |
|
|
what is the universal recipient and what is the universal donair |
AB and O |
|
|
why doesn't negative clump when given to positive |
because the negative doesn't have any antibodies so there is nothing for the Rh+ to attack |
|
|
what are the four types of immunity |
skin- produces sebum mucus- traps foreign particles HCL- denatures pathogens in stomach |
|
|
describe phagocytosis |
engulf pathogens and digests them with enzymes and macrophages |
|
|
what do killer T cells do |
they clump pathogens so they cannot attach to other cells or infect anything |
|
|
what do suppressor T cells do |
calm down killer t so they don't clump everything |
|
|
what do memory B and t cells do |
remember how to make antibodies to kill viruses |
|
|
define leucocytes and lymphocytes |
leucocytes are white blood cells lymphocytes are B and T cells |
|
|
define active immunity |
needs to come into contact with pathogen to make antibodies |
|
|
define passive immunity |
antibodies are given to an individual |
|
|
what is the process for blood clotting |
thembrytes -> thromboplastin -> {prothrombin -> thromition} -> { finriegen -> fibin} -> seeb |
|
|
what is hypertension |
high blood pressure |
|
|
what is varicose veins |
backflow in veins due to loose valves |
|
|

crack in artery due to forced pulse |
|
|
what is heart attack |
blocked artery |
|
|
what is edima |
dropping plasma protein |
|
|
what is anemia |
lacking iron so can't make RBC |
|
|
what is stroke |
blocked artery in brain |
|
|
what is hemophilia |
missing factors so you can't blood clot properly |
|
|
what is the pericardium |
sac surrounding heart that protects it from shock |
|
|
define heart murmur |
when one or more valves is not opening or closing properly |
|
|
where is hemoglobin found and what does it do |
in RBC transports oxygen to other parts of body |
