Cardio II- Heart and Circulation

arteries

carry blood away from the heart

branch as they move away from heart

usually carry oxygenated blood (2 exceptions)

veins

carry blood toward the heart

merge as they move toward heart

usually carry deoxygenated blood (2 exceptions)

artery and vein exceptions

pulmonary and umbilical artery and vein

roles reversed

where does deoxygenated blood enter from?

superior and inferior vena cava

where do the vena cavas empty into?

right atrium

what opens the tricuspid valve?

chordae tendinae attached to papillary muscle pull it

where is the tricuspid valve located?

between the right atrium and ventricle

where does blood go after the right ventricle?

to the lungs via the pulmonary (semilunar valve)

where do the pulmonary veins empty into?

left atrium

where is the bicuspid valve located?

between the left atrium and ventricle

where does the left ventricle send blood to?

the aorta, blood gets sent throughout the body

fetal heart bypasses

shuttle oxygenated blood away from the developing, non-functional lungs

foramen ovale and ductus arteriosus

foramen ovale location

between left and right atria, hole

ductus arteriosus location

pulmonary artery/trunk to aorta, shunt

ductus venosus

branch off the umbilical vein that goes to the right atrium with oxygenated blood, bypasses liver

is there a common jugular vein

no
