What are the four major blood types?
A, AB, B, O
What blood type is the universal recipient?
AB
largest blood vessel in the body
aorta
valve between the left ventricle and the aorta
aortic semilunar valve
blood vessels which leave the heart
arteries
smaller divisons of an artery
arterioles
bring blood to the capillaries
arterioles
pertaining to both arteries and veins
arteriovenous
upper chambers of the heart
atria
located on the floor of the right atrium, transmits the electrical signals from the SA node to the bundle of His
atrioventricular node
listening to body sounds
auscultation
WBCs formed in red bone marrow, least common WBC, responsible for symptoms of allergies
basophils
valve located between the left atrium and left ventricle, has two cusps
bicuspid valve
fluid tissue that transports oxygen and nutrients to body tissues
blood
thrombus
blood clot formed within a blood vessel and remaining attached to its place of origin
gases that are normally dissolved in the liquid portion of blood
blood gases
measurement of the amount of pressure on an artery wall
blood pressure
three arteries that come off of the aortic arch
brachiocephalic, left common carotid, subclavian
group of fibers located in the interventricular septum; carry an electrical impulse to the ventricles and Purkinje fibers
bundle of His
smallest blood vessels in the body
capillaries
pertaining to the heart and blood vessels
cardiovascular
major arteries that carry blood to the head
carotid arteries
embolus
clot that breaks lose and travels through the bloodstream
P wave
contraction of the atria
QRS complex
contraction of the ventricles and realxation of the atria
arteries which supply oxygen-rich blood to the myocardium
coronary arteries
veins located away from the body surface
deep veins
relaxation phase of the heart
diastole
pressure that occurs when the ventricles are relaxed
diastolic pressure
process of recording the heart’s electrical activity
electrocardiogram
