The path which the blood flows through during pulmonary circulation is : (i) RA → RV Pulmonary arteries → Lungs → Pulmonary veins → LA
RA- The sequence starts from right auricle. Deoxygenated blood from various parts of body is brought to the right auricle through the aorta.
RV- Deoxygenated blood from RA is poured into RV as bicuspid valve opens.
Pulmonary arteries- From RV, deoxygenated blood flows into pulmonary arteries as the semilunar valve opens.
Lungs- Deoxygenated blood is oxygenated in the lungs.
Pulmonary veins- Oxygenated blood from lungs flows into pulmonary veins.
LA- Oxygenated blood reaches left ventricle through pulmonary veins. From LV, blood flows into LA.
