Flashcards in CV 5 Special Circulations Deck (14):
1

Lymph where has protein, where it doesnt have protein

Lymph in liver has protein

Everywhere else is protein free

2

Pattern of coronary arteries

Right and left coronary arteries come off of aorta and loop around posteriorly

L gives off LAD and circumflex and posterior descending

3

Which vessels feed

Most of LV

Some of RV

Rest of LV

LCA and LAD

LCA and LAD

Circumflex

4

What is inhibited flow during systole

Left ventricle

5

Special components of fetal circulation

5

2 umbilical arteries
1 umbilical vein
Ductus venosus
Foramen ovale
Ductus arteriosus

6

What has most oxygenated blood in fetus

Umbilical vein

7

Umbilical vein goes to ___ through ___. Then into ___, ___ then __ __

Ductus venosus
Liver
IVC
Foramen ovale

8

After foramen ovale blood goes through __ __ and __ __ to __ __

Pulmonary artery
Ductus arteriosus
Umbilical arteries

9

Physiologic changes upon birth

Lungs fill with air, resistance in lungs go down, switch to RA having higher pressure than LA

Clamp off circulation to placenta, SVR goes up

Foramen ovale shuts with first breath

Umb vein becomes ligamentum teres, umbilical ligaments remain from umb arteries

10

What two things close shortly after birth

Ductus arteriosus over a week

Ligamentum arteriosum over a month

11

Path of best o2 in fetus

Umbicilical vein
Ductus venosus
Hepatic vein
Ivc
Foramen ovale
La and lv
Aorta
Brachiocephalic and l common carotid
Right and left sides of brain

12

Path of less o2 blood in fetus

Umb vein
Ductus venosus
Hepatic vein
Ivc
Right atrium, tricuspid, r ventricle
Pulm artery, lungs
Ductus arteriosus
Joins aorta w more o2 blood
Lower body

13

When you exercise what gets less flow

Skin (except when you get hot)
Kidneys
Gi tract

14

Flow same or increase when exercising

Brain same
Extra flow to lungs and muscles
