9

ox/i

10

thromb/o

11

Heart

The Center of the cardiovascular system, wt. 300g, circulated the blood through the heart, lungs, and the rest of the body.

12

Arteries

Branching system of vessels that transports blood from the right and left ventricles to all body parts. Transports blood away from the heart.

13

Veins

Transports blood from peripheral tissues back to the heart

14

Capillaries

Microscopic blood vessels that connect arterioles with venues; facilitate passages of life-sustaining fluids containing oxygen and nutrients to cell bodies and the removal of accumulated waste and carbon dioxide

15

Blood

Fluid consisting of formed elements and plasma. Specialized bodily fluid that delivers necessary substances to the body's cells. Blood is circulated through blood vessels by the pumping action of the heart.

16

Endocardium

Inner lining of the heart.

17

Myocardium

Muscular middle layer of the heart

18

Pericardium

The outer membranous sac surrounding the heart

19

Septum

The divider of the right and left sides of the heart

20

Atria

The upper chambers of the heart

21

Ventricles

The lower chambers of the heart

22

Right atrium

Upper right portion of the heart.

23

Superior vena cava and inferior vena cava

Bring deoxygenated blood into the right atrium

24

Rt. ventricle

Right lower portion of the heart. It receives blood from the rt. atrium through the tricuspid valve

25

Pulmonary artery

The only artery in the body to carry deoxygenated blood.

26

Left atrium

Receives oxygen rich blood from the lungs via the right and left pulmonary veins. The pressure from the oxygen forces open the bicuspid (mitral) valve and fills the left ventricle

27

Left Ventricle

Left lower portion of the heart. It receives blood from the left atrium through the mitral valve or bicuspid valve. The oxygenated blood from the LV flows through the aortic valve and into the aorta to all parts of the body.

28

Tricuspid or right atrioventricular valve

Guards the opening between the right atrium and right ventricle

29

Pulmonary (semilunar) valve

The exit point for blood leaving the right ventricle

30

Bicuspid or mitral valve

The valve between the left atrium and ventricle

31

Aortic or semilunar valve

Blood exits the left ventricle through this between the left ventricle and aorta

32

Anastomosis

Surgical condition between blood vessels or the joining of one hollow or tubular organ to another.

33

Aneurysm

Abnormal widening or ballooning of a portion of a artery due to weakness in the wall of the blood vessel.

34

Angiogram

X-Ray record of the size, shape and location of the heart and it's blood vessels after radiopaque contrast

35

Angioplasty

Surgical repair of a blood vessel

36

Arrhythmia

Loss of rhythm of the heartbeat, also called dysrhythmia.

37

Arteriosclerosis

Hardening of arteries.

38

Atheroma

Tumor of a artery containing a fatty substance

39

Auscultation

Method of physical assessment using a stephoscope to listen to the sounds within the chest.
