cardiorespiratory 1 Flashcards
esophageal hiatus
transmits esophagus, vagal n and esophageal vessels
most centrally located
aortic hiatus
passageway for aorta, azygos v and thoracic duct
cava foramen
at junction of tendinous and muscular parts of right diaphragm
secondary inspirator mm
serratus dorsalis cranialis
external intercostal
rectus thoracis
scalenius
expiration mm
serratus dorsalis caudalis
internal intercostal m
pleura
serosa membrane around thorax
pericardium
serosa around heart
peritoneum
serosa around abdomen
mediastinum
central area of thorax
cranial, middle and caudal portions
endothoracic fascia
connective tissue that glue parietal pleura with ribs and intercostal muscles
pleura cupula
very cranial
where serosa pass 1st rib and into neck
fibrous pericardium
outermost layer
keeps heart in the middle of thorax
anatomical pericardium
parietal serosa pericardium
visceral pericardium
pericardial cavity (space between parietal and visceral)
clinical pericardium
layers are fused together
pericardial mediastinal pleura
fibrous pericardium
parietal serous pericardium
phrenicopericardial lig
connects fibrous pericardium to sternal part of diaphragm
pulmonary circulation
between heart and lungs
right side
systematic circulation
between heart and whole body
left side
lymphatic system
responsible for immunological defense of the body
receive ICF, filter and release
epicardium
serous membrane and thin layer of loose CT
myocardium
muscle layer
endocardium
covers everything inside the heart
base of heart
points dorsally, thicker part of heart
apex of heart
points ventrally, most ventral portion of heart
aricular face
surface of heart facing LEFT side of thorax
see both auricles and mainly left ventricle
