histology of cardiovascular system Flashcards
what is the basic histological plan of the heart and blood vessels
innermost epithelium, a middle muscle layer, and an outer connective tissue layer.
what are the layers of the heart and blood vessels known as
tunica intima, tunica media and tunica externa/adventitia.
what are these layers known as in the heart
endocardium, myocardium, epicardium.
what are the three main histological types of arteries
elastic arteries, muscular arteries and arterioles.
what are the three main histological types of arteries
elastic arteries, muscular arteries and arterioles.
muscular arteries
has a tunica intima with a prominent internal elastic lamina and tunica media with a prominent smooth muscle component
elastic arteries
those nearest the heart (aorta and pulmonary arteries) that contain much more elastic tissue in the tunica media than muscular arteries
elastic arteries
those nearest the heart (aorta and pulmonary arteries) that contain much more elastic tissue in the tunica media than muscular arteries
vasa vasorum
“vessels to the vessels”. Small blood vessels that supply the walls of larger arteries and veins are known as vasa vasorum. These blood vessels supply the outer wall (externa) of large arteries and veins.

in which groups of draining lymph nodes might you look for evidence of metastases from a primary tumour located in the upper right quadrant of the left breast?
last auxiliary lymph nodes
What type of artery are the radial and femoral arteries?
elastic - distributing
Why is the tunica media the broadest layer in arterioles?
greater surface area to link with venue ls /veins
what structures would a 4inch knife blade pass through following a stab wound in the 6th intercostal space of the anterior thorax in the right midclavicular line?
right middle lobe lung possibly pulmonary artery / vein
What type of artery are the aorta and pulmonary trunk?
conducting - muscular
