Week 3 Flashcards
what cavity is the lungs in
the plueral cavity
what surrounds the lungs
two pairs of sacs filled with fluid
parietal and visceral pleura
how do lungs form
plueral cavity is formed then from the trachea the lungs grow into the plueral cavity
parietal pluera
outside of cavity
visceral pluera
inside touching lung
what does the plueral cavity allow the lungs
cushioning that allows it to exist in a more frictionless environment
allows lungs to expand
hilum
are complicated anatomical structures containing the pulmonary vessels and the major bronchi, arranged asymmetrically
right medial lung anterior to posterior
right superior pulmonary vein
right pulmonary artery
right main bronchus
right inferior pulmonary vein
left medial lung top to bottom
left pulmonary artery
left main bronchus
left inferior pulmonary vein
left superior pulmonary vein
are trachial rings present on the whole trache
no not on the posterior side
costodiaphragmatic recess
space between diaphragm which is covering the liver and ribcage
pericaridal sac
the sac heart grows into and lives inside of
phrenic nerve (left)
coming down from CNS crosing around and behind the heart innervates the diaphragm
pericadiacophrenic artery
goes with phrenic nerve and supplies blood to the diaphragm
phrenic nerve (right)
also accompanied by a periacadiacophrenic artery
pericardail cavity
sac that heart grows into
fluid filled sac around heart
parietal pericadium
not in contact with the heart
visceral pericardium
in contact with the heart
layers of heart tissues
epicardium
myocardium
endocardium
epicardium
outermost, thin layer formed by the visceral layer of serious pericardium
myocardium
thick middle layer of specialized cardiac muscle
endocardium
innermost thin, smooth layer of epithelial tissue that lines the inner surface of heart chambers and valves
interatrial septum
wall that separates the atriums
right triscuspsid valve
from right atrium into right ventricle
