what are the branches of R coronary A

R marginal A, SA node A, Post. interventriuclar A, AV Nodal A

what does R marginal A supply

right ventricle

what does SA node A supply

SA node

does the L coronary A go all the way around the heart

no

blood flow of L coronary A

L coronary A to Ant. interventricular A to circumflex A to left marginal to post. branch of L ventricle

from fetus to placenta

what is two umbilical A known as in adults

medial umbilical ligament

what does one umbilical vein do

carry oxygen rich blood to fetus

what is one umbilical vein known as in adults

round ligament of liver

what does the ductus venosus do

allows most blood to bypass the fetal liver and go straight to heart

what is ductus venosus known as in adults

ligamentum venosum in adults

what are two ways to bypass the lungs called

foramen ovale, ductus arteriosus

what does foramen ovale do

allows blood to shunt between 2 atria

foramen ovale

foramen ovale bypasses what and go straight into what

lungs, heart

what is closed in 90% of the population

foramen ovale

what does foramen ovale turn into for adults

fossa ovalis

what does ductus arteriosus do

connects pulmonary trunk with aorta

what does ductus arteriosus enable

most blood to bypass fetal lungs

what does ductus arteriosus turn into in adults

ligamentum arteriosum

arteriosclerosis:

thickening of vessel walls and reduction in diameter (hardening of A)

aneursym:

bulge in weakened wall of a blood vessel

with aneursym what do people die from

ruptured aneursyms

where is aortic aneursym located?

thoracic/ abdominal region

coronary bypass

double-quintuple

angioplasty

small catheter like device with a balloon on tip is inserted into femoral region. the ballon is blown up to mkae plaque stick to walls
