Review for Cardiovascular system part 1 notes Flashcards
Systemic Circulation-
delivers the blood to all body cells and carries away waste
Pulmonary circulation-
eliminates carbon dioxide and oxygenates blood (lung pathway)
Arteries-
carry blood AWAY from the heart
Veins-
return blood to the heart
What is the heart size?
about 14 cm x 9 cm (the size of a fist)
What does the Visceral Pericardium do?
IT encloses the heart (like a bag) very thin layer
What does the pericardial cavity do?
It contains the fluid for the heart to float in and enables the heart to have little to no friction
What are the layers of the heart?
Epicardium- outer layer, reduces fricion
Myocardium- middle layer, mostly cardiac muscle
Endocardium- inner layer, blood vessels and Purkinje fiber
