1

Location of the heart?

Mediastinum

2

Pointed end of the heart.

Apex

3

What are the main structures of the heart? (5)

-Pericardium
-Wall
-Chambers
-Valves
-Great vessels

4

3 parts that make up the parietal pericardium

-Fibrous connective tissue
-Mesothelium
-Areolar tissue

5

Also called the epicardium

Visceral Pericardium

6

2 parts that make up the visceral pericardium.

-Meosthelium
-Areolar tissue

7

Layers of the heart wall (3)

-Epicardium
-Myocardium
-Endocardium

8

OUTER layer of heart wall also called visceral pericardium.

Epicardium

9

MIDDLE layer of heart wall that is composed of cardiac muscle tissue.

Myocardium

10

Thin DEEP layer of heart wall made up of simple squamouse endothelium and areolar tissue that lines the inside of the myocardium.

Endocardium

11

Chamber of the heart that receives deoxygenated blood from superior and inferior vena cava and the foramen of the coronary sinus.

Right Atrium

12

Chamber of the heart that receives oxygenated blood from two left and two right pulmonary veins.

Left Atrium

13

Chamber of the heart that pumps deoxygenated blood into the lungs.

Right Ventricle

14

Chamber of the heart that is a thicker ventricle and pumps oxygenated blood through the systemic circuit.

Left Ventricle

15

Separates the two atria.

Interatrial septum

16

Opening in the septum during fetal development.

Foramen ovale

17

Small depression in the septum resulting from the closer of the foramen ovale after birth.

Fossa ovalis

18

Muscles in anterior of atrial wall.

Pectinate muscles

19

Expandable sections in both the left and right atria.

Auricles

20

Wall separating the two ventricles.

Interventricular septum

21

Ridged inner surface of both ventricles

Trabeculae carneae

22

Tendons that attach each cusp of the atrioventricular valves to the papillary muscles.

Chordae tendineae

23

Muscles in ventricles which contract to tighten the chordae tendineae to limit the movements of the valves and anchor cusps of atrioventricular valves to heart wall.

Papillary muscles

24

4 valves of the heart

-Right atrioventricular valve
-Left atrioventricular vavle
-Pulmonary semilunar valve
-Aortic semilunar valve

25

Tricuspid valve

Right atrioventricular valve

26

Biscupid valve or mitral valve

Left atrioventricular valve
