Flashcards in The Heart #2 Block 1 Deck (55):
1

what will happen if the right side of the heart became large? more than 1/3

you would think that the right ventricle could be enlarged

2

how much of the heart is on the left side

2/3

3

the heart has what kind of axis?

usually anterior and downward, oblique

4

the electrical axis of the heart is how much?

60 degrees

5

artria and verntricals are separated by what?

atrioventricular groove ( sulcus)

6

what separates the left and right ventricle

the inter ventricular groove

7

what is inside the interventicular groove?

blood vessels

8

what is the shape of the heart

tilted pyramid

9

how many borders are in the heart

4

10

what is the apex formed by

the inferolateral part of the left ventricle

11

where is the apex located

posterior to the 5th intercostal space in ADULTS

12

when listening to apex you can hear?

mitral valve

13

if you put your finger on the 5th intercostal space you can feel a heart beat why

because that is where the apex is beating

14

where is the base of the heart

the left atrium

15

the base of the heart faces what?

posteriorly to the body of T6-T9

16

what is the base of the heart separated from

the pericardium

17

where is hard to access on the heart

the base of heart

18

what s located superiorly to the bifurcation of the pulmonary trunk

the base of the heart

19

what is the VENOUS portion of the heart

the base of the hear

20

what are the four surfaces of the heart

anterior surface inferiror surface(diaphragmatic) right surface left surface

21

anterior surface of the heart is mainly formed by what

the right ventricle

22

inferior surface of the heart is mainly made of

left and right ventricle

23

what forms the right surface of the heart

the right atrium

24

left surface of the heart is formed by?

left ventricle

25

knowing what surface of the heart you are placing an electrode helps what?

where in the heart you are getting electrical impulse

26

there are four borders of the heart what are they

right inferior left border

27

the right border of the heart is formed by what

right atrium

28

the inferior border is formed by?

right ventricle

29

left border is formed by?

left ventricle

30

superior border is formed by?

right and left atria

31

where is transverse pericardial sinus located

behind the superior border of the chest

32

what is dextrocardia

when the heart is on the right side of the body because of abnormal folding of the embryonic heart

33

dextrocardia may be associated with what

problems of the lungs and problems of the vessels attached to the heart

34

what is a mirror image positioning of the great vessels and the arch of the aorta?

dextocardia

35

if heart is on the right side is this a problem

this is fine usually, unless the other organs are also located on the opposite side

36

situs inversus is what?

when the organs are on the opposite side of the body

37

Katagener syndrome?

this is when a patient has inverted internal organs and the cilia of the bronchi is not working properly, resulting in patient suffering for inflammation in bronchi and frequent pneumonia. Stomach can be on the right side instead of the left.

38

isolated dextocardia

everything is on the right side of the body except for the heart

39

is isolated dextcardia able to be fixed

yes you cut and reattach the parts to the correct origin locations

40

the right atrium has blood coming from where

superior and interior vena cava and the CORONARY SINUS

41

the opening of the coronary sinus is where

in the right atrium

42

he posterior wall of the atrium is formed by?

walls of the superior and inferior vena cava

43

the posterior wall of the right atrium is smooth why

because the walls of the superior and inferior vena cava are smooth

44

anterior wall of the right atrium is formed by what

the pectinate muscles

45

pectinate muscle is what texture

rough, making the anterior wall of the right atrium rough

46

smooth and rough portions of the atrial wall are separated by what?

the crista terminals which is an internal vertical ridge

47

what is the oval, thumbprint size depression that separates the intertribal septum

the fossa ovalis

48

forman oval should be what?

closed, but it isn't always

49

what is in the right atrium?

SA Node

50

can you find an SA node on the right atrium of the heart?

not usually

51

what is the back up node to the SA node

the Atroventicualr node

52

where is the AV node

between right atria and right ventrical

53

where is the bundle of his

in the middle of the right and left ventricle

54
