Answer 1

membrane sac of fibrous tissue fixed to mediastinum that surrounds heart and prevents cardiac tissue overstretching

Question 2

organisation of pericardium

Answer 2

endocardium, myocardium, visceral pericardium, parietal pericardium, fibrous pericardium

Question 3

Answer 3

Question 4

myocardium

Answer 4

thick layer of cardiac muscle cells

Question 5

visceral pericardium

Answer 5

epicardium; layer of serious tissue between myocardium and pericardial space, separating muscle from pericardial fluid

Question 6

parietal pericardium

Answer 6

layer of serous tissue lining fibrous pericardium and facing pericardial space

Question 7

fibrous pericadrium

Answer 7

connective tissue to protect heart and hold its position, as well as prevent overfilling

Question 8

what is in the pericardial space

Answer 8

pericardial fluid (allows lubrication between visceral and parietal pericardium)

Question 9
