Arteries

Blood from the heart to the body

1

Veins

Blood from the body to the heart

2

Arterioles

Small arteries

3

Capillaries

Smallest arterial vessels.

4

Venules

Where vnous return starts at the capillary level... Very small veins... Deoxygenated blood!

5

Tunica Intima

Inner lining of blood vessels (endothelium)

6

Tunica Media

Middle layer of the vessel. Includes smooth muscle portion and is the thickest of layers.

7

Tunica Adventitia

Outer layer of the vessel.

8

Coronary arteries

Artery that supplies the heart muscle (myocardium)

9

Right coronary artery

Devides into branches on the right side of heart.
The branches supply the blood flow to RIGHT ATRIUM and RIGHT VENTRICLE, and under (inferior portion) of the LEFT VENTRICLE.
It also supplied blood to the conduction system(SINUS AND AV NODES)

10

Left coronary artery

Divides into two branches.
Supplies blood to most of the left ventricle, intraventricular septum, and sometimes the AV node.

11

Two branches of the LEFT coronary artery


Left Anterior Descending
Circumflex Coronary Arteries

13

Ascending Aorta

Arises from the lest ventricle. Has two branches (left and right main coronary arteries)

14

Aortic arch

Three major arteries arise from the aortic arch:
brachiocephalic artery
left common carotid artery
left subclavian artery.

15

Descending aorta

Longest portion of the aorta.

Consists of Thoracic and Abdominal aorta.

16

Brachiocephalic

First vessel to branch from the aorta
Divides into right subclavian and right carotid.

17

Carotid bifurcation

Point of division at which the common carotid artery branches into the internal and external carotid.

18

Carotid Sinus

Superior to the carotid bifurcation.... Regulates blood pressure

19

Arteriosclerosis

Calcium deposits in the arterial walls.
Hardens the arteries.
Reduction in blood flow.
Part of coronary artery disease

20

Pulmonary Circulation

Carries blood to the lungs

21

Systemic Circulation

Carries blood to the body (system)

22

Ascending aorta

Arises from the left ventricle and consists of the right and left coronary arteries. CIRCULATION TO THE HEART MUSCLE

23

Carotid Bifurcation

Where the carotid divides into the internal and external carotids

24

Carotid Sinus

In the Carotid Bifurcation. Important in regulating blood pressure.

25

Basilar Artery

Where the left and right vertebral arteries meet.

26

Pons

Mass of nerve fibers at the end of the medulla oblongata

27

Cerebellum

Part of the brain that is dorsal to the Pons and is responsible for coordination and balance.

28

Carotid Canals

Where the arotid arteries enter the cranial vault

29

Cerebral Arteries

Supply blood to the large portions of the brain cortex.

30

Circle of Willis

Interconnection of arteries delivering blood to the brain.

31

Palmer arches

Arteries in the hand from the radial artery and ulnar artery.

32

Visceral Arteries ]

Supply blood to the organs

33

Parietal Arteries

Supply blood to the walls.

34

Raynauds Phenomenon

While and Cool fingertips from stress or cold exposure.

35

Femoral Arteries

big artery by the femur

36

Dorsalis Pedis Artery

Pedal pulse spot. artery on the superior portion of the foot.

37

Mesenteric Angine

Blockage of arterial blood flow to the digestive system.

38

Venous Sinuses

Drain blood from the brain into the internal jugular vein.

39

Hepatic Portal System

Part of the venous system. Drains blood from the liver, stomach, intestines, and spleen.

40

Phlebitis

Inflammation of superficial and small veins

41

Thrombi

Blood clots

42

Pulmonary embolism

Embolism travels into the lungs
