32
Q

Which Coronary artery is considered to have coronary dominance in 80% of people

A

Posterior Descending of the RCA

33
Q

Postnatal Circulation steps

A

1) first breath clears airway and decreases pulmonary pressure in vascular beds
2) decreased pulm. pressure causes blood to enter lungs instead of ductus arteriosus of arch.
3) Blood rushes from lungs to LA closing foreman ovale
4) O2 levels rise in umbilical arteries causing spasm
5) uterus contracts forcing placental blood into fetus. umbilical vein collapses
