Veins carry blood

TOWARD the heart

*they receive blood from nearby structures.

Veins to...

Arteries

7

Tunica intima are ________ cells

Endothelial

8

Tunica intima:endothelial calls

Subendothelial layer of loose connective tissue,
Deepest layer, closest to blood

9

Tunica media are _______ cells

Smooth muscle

10

Tunica media: smooth muscle cells

Elastic and collagen fibers,
Separated by internal elastic lamina

*veins so not have internal elastic lamina

11

Arteriovenuos malformation defined

Direct connection of arterial and venous circulation

12

Arteries carry blood

AWAY from the heart

*they supply blood to structures

13

Arterial anastomosis-

Two arteries join..

What is the advantage?

Arteries that DO NOT follow the "classic" circulation pattern.

Together to feed an anatomical area

The body thinks 2 arteries should go into that area.

14

Arteriovenous malformation defined-

Distributed-

Participate-

Direct connection of arterial and venous circulation.

Throughout body in small vessels.

In several physiologic processes.

15

The 3 layers of arteries

Tunica intima-deep
Tunica media-middle
Tunica adventitia-outer

16

The tunica media and tunica intima are seperated by
And
The tunica media and tunic adventitia are seperated by

Internal elastic lamina
Exernal elastic lamina

17

Vasa vosorum

Vessel within a vessel
*small vessels within that supply the adventitia

18

Major arteries AWAY from the heart

Aortic arch->brachiocephalic artery which branches into right common carotid and right subclavian


Aortic arch->left common carotid and left subclavian
