Flashcards in Heart Circulation Deck (38):
1

Mediastinum

Space between the lungs

2

Myocardium

Heard Muscle

3

Pericardium

Surrounding Membrane of the heart

4

Serous Paricardium

Inner membrane of paricardium

5

Visceral layer

Inner layer of the Serous Paricardium. EPICARDIUM

6

Parietal Layer

Outer layer of the Serous Paricardium.

7

Paricardial Fluid

Fluid within paricardial sac

8

Myocardial Infarction

Complete blockage of an artery that supplies oxygen to the heart muscle.

9

Interatrial Septum

Seperates the two atria down the middle.

10

Interventricular Septum

Seperates the two ventricles down the middle.

11

Ventricles

Lower portions of the heart. PUMPS blood to the body.

12

Atriums

Upper portions of the heart. RECEIVES blood from the body.

13

Coronary Sinus

Veins that collect blood that is returning from the walls of the heart.

14

Foramen Ovale

Opening between the two atria that is present in the fetus.

15

Atrioventricular Valves

Valves that are between that atria and ventricle.

16

Tricuspid Valve

Seperates RIGHT ATRIUM and RIGHT VENTRICLE

17

Mitral Valve

Seperates LEFT ATRIUM and LEFT VENTRICLE

18

Semilunar Valves

Between the ARTERIES and VENTRICLES.

19

Pulmonic Valve

Between the right ventricle and pulmonary arterie. Prevent Backflow.

20

Aortic Valve

Between the left ventricle and the aorta (systemic arterie). Prevent Backflow.

21

Superior Vena Cava

Returns deoxygenated blood from the UPPER BODY to heart via the right atrium.

22

Inferior Vena Cava

Returns deoxygenated blood from the LOWER BODY to heart via the right atrium.

23

AORTA

Largest artery in body.

24

Left Ventricle

Largest of the four cardiac chambers, and is responsible for pumping blood to the entire body.

25

Left Atrium

Receives oxygenated blood from lungs.

26

Right Atrium

Receives deoxygenated blood from body.

27

Right Ventricle

Pumps deoxygenated blood to the lungs.

28

S1

lub. CONTRACTION. Closure of the mitral and tricuspid valves.

29

S2

DUB. RELAXATION. Closure of the pulmonic and aortic valves.

30

S3

da. After S2. Soft and low pitched. "lub-DUB-da". Typically rapid ventricular filling due to inrush of blood. Can be an indication of heart failure.

31

S4

bla. Before S1. Increased arterial pressure OR decreased compliance of the left ventricle.

32

Paricarditis

Infection or Inflammation of the paricardial membrane. Chest pain!

33

Pericardial Effusion

Pericardial Sac fills with too much fluid

34

Pericardial Tamponade

Pericardial Effusion with shock due to the hearts inability to fill effectively.

35

Pericardiocentesis

Needle placed into the pericardial sac to remove fluid.

36

Rheumatic Fever

Damage to aortic and mitral valves. Forward blood flow is decreased. Normally in young adults or children.

37

Ischemia

Damage to cells. Arterial blood flow to heart tissue is decreased resulting in a lack of oxygen to that site.

38

Endocarditis

Infection of heart valve.
