(W1 BQ) what indicates the fetal foramen ovale-where blood was shunted from right atrium to left atrium in the fetus
fossa ovalis
what is known as the heart strings
the tendinous cords
what is known as the pacemaker of the heart
sino-atrial node
what is known as the bundle of His
atrioventricular bundle
what is the circulation of blood through the heart
superior vena cava/inferior vena cava -> right atrium -> tricuspid valve -> right ventricle -> pulmonary valve -> pulmonary artery -> lungs -> left atrium -> mitral valve -> left ventricle -> aortic valve -> aorta -> rest of body
which parts of the circulation are oxygenated and which are deoxygenated
everything before lungs - deoxygenated (superior vena cava/inferior vena cava -> right atrium -> tricuspid valve -> right ventricle -> pulmonary valve -> pulmonary artery) and everything after lungs - oxygenated (left atrium -> mitral valve -> left ventricle -> aortic valve -> aorta -> rest of body)
