| which temporary structure does blood flow to from the umbilical vein | ductus venosus |
| where does the inferior vena cava connect to | right atrium |
| blood flows through the foramen ovale into the... | left atrium |
| blood from the superior vena cava goes to the | right atrium and then the right VENTRICLE |
| from the left ventricle blood flows to the... | ascending aorta |
| the ascending aorta supplies blood to | the brain and heart-> sup vena cava and the descending aorta |
| blood from the right ventricle is transported via the.. | pulmonary artery |
| the pulmonary artery pushes blood to the (x2) | ductus arteriosis-> descending aorta and the lungs->left ventricle |
| after birth, flow through what stops? | ductus venosus |
| the haltof flow throught the ductus venosus causes.. | fall in pressure in the R atrium |
| a fall in pressure in the right atrium causes what | the foramen ovale to close |
| when the foramen ovale closes, what happens? | blood flows to the right ventricle, pulmonary artery and then lungs which inflate due to decreased pulmonary resistance |
| what is released from the lungs that causes the ductus arteriosus to close | bradykinin |
