1

Return blood to the heart.

Veins

2

Carry blood away from the heart.

Arteries

3

What are the 3 parts of the aorta?

-Ascending aorta
-Aortic arch
-Descending aorta

4

What are the 3 major vessels that the aortic arch branches off into?

-Brachiocephalic trunk
-Left common carotid artery
-Left subclavian artery

5

2 branches of the brachiocephalic trunk?

-Right subclavian artery
-Right common carotid artery

6

Formed by the internal carotid artery, anterior and posterior cerebral arteries, (but not middle) and communicating arteries.

Circle of Willis

7

NOT part of the circle of Willis

Middle cerebral arteries

8

Begins at T5 and extends to T12.

Thoracic aorta

9

Begins inferior to diaphragm.

Abdominal aorta

10

Receives blood from organs in the superior part of the body (neck, head, chest, shoulders, and upper limbs)

Superior vena cava

11

Receives blood from organs inferior to the diaphragm (Abdominal organs and lower limbs)

Inferior vena cava

12

Exchanges nutrients, wastes and gases (O2/CO2) between fetal and maternal blood.

Placenta

13

Functions of Umbilical arteries?

-Blood enters umbilical cord from the internal iliac arteries of fetus.
-Carries fetal blood to the placenta (This blood is O2 poor and CO2 rich)
-Become lateral bladder ligaments

14

Functions of Umbilical vein?

-Carries blood from the placenta through the umbilical cord to the fetus (This blood is O2 and nutrient rich)
-Umbilical vein drains into the ductus venosus
-Ductus venosus drains into the inferior vena cava
-Umbilical vein becomes the round ligament of the liver

15

What are the 3 shunts of the fetal heart?

-Ductus venosus
-Foramen ovale
-Ductus arteriosus

16

Opening in the interatria septum that allows blood to bypass the lungs.

Foramen ovale

17

Connects the pulmonary trunk with the aorta to allow blood to bypass the lungs.

Ductus arteriosus
