two circuits of heart

pulmonary, systemic

1

circuit of heart to lungs and back and oxygenates blood

pulmonary

2

circuit of heart that is to body and back and delivers oxygen to tissues

systemic

3

the heart is inside the blank

pericardial cavity

4

heart is inside blank

mediastinum

5

the heart is blank tipped toward the inferior and left

apex

6

double serous membrane with fibrous coat that is made of several layers

pericardium

7

two layers of pericardium

parietal pericardium, epicardium

8

this is between layers of pericardium and contains serous fluid

pericardial cavity

9

outer layer of pericardium that is the outer layer and has a fibrous and areolar layer

parietal pericardium

10

this is known as the visceral pericardium and functions as a protective outer layer

epicardium

11

middle layer of the heart that is responsible for contractions and made of cardiac muscle

myocardium

12

this is the inner layer of the heart and lines and protects chambers and valves and is continuous with endothelium of heart blood vessels

endocardium

13

cells of heart are all connected by blank

intercalated discs

14

these are superior to the ventricles and receive blood from blank

atria, veins

15

atria have blank which are flaps where blood pools

auricles

16

these are inferior chambers of heart that force blood out to arteries

ventricles

17

left ventricles are blank than right

thicker/stronger
