heart + cardiovascular system Flashcards
five types of blood vessels
arteries, arterioles, capilaries, venuoles, veins
what surrounds the heart
pericardium
what is the muscle of the heart called
myocardium
chambers of heart in order of bloodflow
right atrium, right ventricle, left atrium, left ventricle
what artery carries DO2 blood
pulmonary artery/arteries
major branches of left coronary artery
circumflex branch, anterior interventricular branch (LAD)
major branches of right coronary artery
right marginal artery, posterior interventricular branch
2 cardiac veins
great cardiac vein, middle cardiac vein
blood is made up of plasma + WHAT
formed elements. red + white blood cells, platelets.
through what does blood enter the heart
DO2 blood enters right atrium through the inferior and superior vena cava and the coronary sinus
what valve is between the right atrium and ventricle
right atrioventricular valve or tricuspid
what valve is between the left atrium and ventricle
left atrioventricular valve or bicuspid or MITRAL
what valve must blood pass through to get from the right ventricle to the pulmonary trunk
the pulmonary valve (or pulmonary semilunar)
what valve must blood pass through to exit the heart
the aortic valve (or aortic semilunar)
what three vessels branch off of aortic arch
brachiocephalic trunk, left carotid artery, left subclavian artery
