Flashcards in Chapter 14 - The Heart Deck (42):
1

Perfusion

Blood flow through tissues

2

Heart murmur

Abnormal sounds associated with the turbulent flow of blood

3

Constriction

Narrowing of the blood vessel diameter

4

Vasculitis

Inflammation of a blood or lymph vessel

5

Dilation

Widening of a blood vessel diameter

6

Capillaries

Single-cell-thick vessels that connect the arterial and venous systems

7

Veins

Vessels that return blood to the heart

8

Arteries

Vessels that carry blood away from the heart

9

Prophylaxis

Prevention

10

Occlusion

Blockage in a vessel or passageway in the body

11

Ischemia

Deficiency in the blood supply

12

Patent

Open

13

Thrombus

Blood clot attached to the interior wall of a vein or artery

14

Necrosis

Death of cells

15

Plaque

Patch or raised area

16

Insufficiency

Inability to preform at proper level

17

Viscosity

Resistance to flow

18

Thrill

Vibration felt on palpation

19

Stenosis

Narrowing

20

Infarction

Localized area of necrosis caused by interrupted blood supply

21

Hemostasis

Control or stoppage of bleeding

22

Tricuspid valve

The right Atrioventricular valve that blood passes through from the right atrium to the right ventricle

23

Pericardium

The double-walled membranous sac enclosing the heart

24

Septum

A partition or wall separating something

25

Transfusion

Introduction of whole blood or blood components into the blood stream of the recipient

26

Cardiomegaly

Heart enlargement

27

Pulmonary arteries

Blood vessels that carry blood from the heart to the lungs

28

Systole

Contraction phase of the heartbeat

29

Diastole

Relaxation phase of the heartbeat

30

Epicardium

The external layer of the heart

31

Mitral valve

The left AV valve also called the bicuspid valve. Blood flows through the valve from the left atrium to the left ventricle

32

Right ventricle

Heart chamber that pumps blood to the lungs

33

Heart chambers?

Atrium and ventricle

34

Sphygmomanometer

Instrument used to measure blood pressure (pressure cuff)

35

Ventricular septal defect

Opening in the wall dividing the right and left ventricles that may allow blood to shunt from the right ventricle to the left ventricle without becoming oxygenated. Abb. VSD

36

Shunt

To bypass or divert

37

Cardiomyopathy

Disease of the heart muscle

38

Coronary arteries

Provides the blood supply to the myocardium

39

Cor pulmonale

Alterations in the structure or function of the right ventricle caused by pulmonary hypertension (pulmonary heart disease) which results in failure of the right ventricle to pump blood properly

40

Lumen

The opening in a vessel through which fluid flows

41

What does COR mean?

Heart

42

iatrogenic

Disease produced by treatment
