Circulatory System: Heart

Question 1

What is the Flow of deoxygenated blood through the heart?

Answer 1

-Deoxygenated blood enter the RIGHT ATRIUM via SUPERIOR & INFERIOR VENA CAVA
-DO blood is pumped from RA to the RIGHT VENTRICLE
-DO blood is pumped from RV to the lungs and to be oxygenated.

Question 2

What is the flow of oxygenated blood through the heart?

Answer 2

OXYGENATED blood enter the LEFT ATRIUM from the lungs via the RIGHT AND LEFT PULMONARY VEINS
