1

Major function of the cardiovascular system

Transportation

2

Delivery route is through the heart...

vessels

3

Transport medium of the heart is through

blood

4

outermost loose fitting, superficial part of the sac

fibrous pericardium

5

What is the double sac wall that encloses the heart

pericardium

6

What are the roles of the fibrous pericaridum?

Protects the heart, anchors the heart to surrounding structures, prevents overfilling the heart with blood.

7

Deep to the fibrous pericardium

serous pericardium

8

lines the internal surface of the fibrous pericardium

pariteal layer

9

At the base of the heart the parietal layer reflect back covering the external surface of the heart

Visecreal layer or epipericardium

10

What two layers make up the serous pericardium?

Partieal layer and visecreal layer

11

What are the three layers that make up the walls of the heart

epicardium, myocardium, endocardium

12

The outer layer, which is also the visceral pericardium“upon the heart”

epicardium

13

Known as the "heart muscle"

Myocardium

14

Middle and thickest layer composed mainly of cardiac muscle

Myocardium

15

Known as the "inside of the heart"

Endocardium

16

Inner lining that covers the heart valves and is continuous with the inner lining of the great vessels

Endocardium

17

Continuous with the endothelial lining of blood vessels

Endocardium

18

How many chambers are in the heart

4

19

How are the four chambers of the heart divided?

2 superior atria and 2 inferior ventricles

20

divides the atria chambers

Interatrial septum

21

divides the ventricle chambers

interventricle septum

22

How are chambers of the heart divided ?

Longitudinally by a septum

23

eceiving chambers and ineffective pumps

Atria

24

Thick wall discharging chambers of the heart

ventricles

25

Two visible grooves on the surface indicating boundaries of chambers and carry blood vessels

cornary sulcus and the anterior interventricle sulcus

26

encircles junction of the atria and ventricles like a crown

cornary sulcus

27

what seperates the right and left ventricles

anterior interventricle sulcus

28

What are the four heart valves

Atrioventricular valves, semilunar valves, Tricuspid valve, mitral valve.

29

Valve between atrium and ventricle

Atrioventricular valve

30

Between the ventricle and great vessel

semilunar valve
