Unit 4- Cardiovascular Pathways Flashcards
(34 cards)
The contraction of the left ventricle is the driving force for the systemic circulation. Systemic arteries are _____________. The oxygen traveling within systemic arteries diffuses ____________ tissues from ___________ capillary beds. Systemic veins carry less-oxygenated blood to the _______________ side of the heart.
oxygenated
unsure/ systemic
right
The contraction of the right ventricle is the driving force for the pulmonary circulation. Pulmonary arteries are ______________. Oxygenation occurs in _______________ capillary beds within the lungs. Pulmonary veins carry oxygenated blood to the ________ side of the heart.
deoxygenated
pulmonary
left
Compare the thickness of the two ventricular walls. Why are they of different thickness?
Right ventricular wall in thin because it only pumps blood to the lungs and blood pressure in pulmonary trunk and arteries is low
Left ventricular wall is thick because is pumps blood to the entire body and the blood pressure in aorta and systemic arteries is high
