1

blunt rounded point of heart

apex

2

larger flat part

base

3

located in

thoracic cavity

4

formed by the pericardium

pericardial caivty

5

anchors heart within mediastinum

pericardial cavity

6

2 layers of pericardium

fibrous and serous

7

tissue that surrounds the heart

pericardium

8

tough fibrous outer layer of CT
layer of pericardium

fibrous

9

inner layer of epithelial cells
layer of pericardium

serous

10

portion of the serous pericardium lining the fibrous pericardium

Parietal pericardium –

11

portion covering the heart

Visceral pericardium or Epicardium –

12

– produced by serous pericardium
-helps reduce friction as the heart moves within the pericardium

pericardial fluid

13

separates atria from ventricles

Coronary sulcus –

14

grooves which indicate the division between right and left ventricles

Anterior and posterior interventricular sulcus –

15

Veins carrying blood to the heart

superior and inferior vena cava
pulmonary veins

16

Arteries carrying blood away from the heart

aorta and pulmonary trunj

17

-receive blood from veins
-primarily function as reservoirs
-contraction of the__ forces blood into the ventricles

atria

18

Right atrium receives blood through 3 major openings:

SVC, IVC, Coronary sinus

19

Left atrium receives blood through

pulmonary veins

20

partition separating the two atria

Interatrial septum –

21

– pumps blood into pulmonary trunk

right ventricle

22

pumps blood into aorta

left ventricle

23

- partition separating the two ventricles

Interventricular septum

24

between right atrium and right ventricle and between left atrium and left ventricle
-allow blood to flow from the atria

Atrioventricular valves –

25

cone-shaped, muscular pillars in each ventricle

Papillary muscles –

26

– three, pocketlike semilunar cusps
-possessed by aorta and pulmonary trunk

semilunar valves

27

– plate of CT
-consists of fibrous rings that surround the AV and semilunar valves

cardiac skeleton

28

– supply blood to the wall of the heart
-originate from the base of the aorta

coronary arteries

29

3 Major Branches of left coronary artery

1. Anterior interventricular artery
2. Circumflex artery
3. Left marginal artery

30

Major Branches of right coronary artery

1. Posterior interventricular artery
2. Right marginal artery
