Thorax 2 Flashcards
what is present in the Inferior middle mediastinum
heart
pericardium
roots of great vessels
4 chambers of the heart
right/left atrium (receiving)
right/ left ventricle (discharging)
what does the right heart receive
venous blood via the SVC and IVC
where does the blood from the right ventricle go
pumps poorly oxygenated blood to the lungs via the pulmonary trunk/arteries
what does the left atrium receive
well oxygenated blood from the lungs via pulmonary veins
where does the left ventricle pump blood
pumps blood into the aorta for systemic distribution
what is pericardium
fibroserous membrane: covers heart and roots of great vessels
what are the two layers of pericardium
fibrous
serous (parietal and visceral)
what is the pericardial cavity
potential space between Visceral and parietal layers of serous pericardium
how would you find the coronary vessels
located within grooves
covered with visceral pericardium
embedded in fat
what branches off the left coronary artery
circumflex and anterior interventricular artery
what are the branches of the right coronary artery
sinoatrial nodal artery
marginal artery
what makes up the posterior interventricular artery
circumflex artery and the right coronary artery
coronary veins
anterior cardiac veins
coronary sinus
where is the coronary sinus located
posterior aspect of the heart
above the circumflex artery
