Answer
The deoxygenated blood first enters the right atrium then it goes to following parts :
1. atrioventricular tricuspid valve
2. right ventricle
3. semilunar pulmonic valve
4. pulmonary artery
5. lungs
Lungs provides oxygen to the blood and oxygenates it. From there the oxygenated blood moves to following parts goes to pulmonary veins which takes it to the left atrium.
This circuit which takes deoxygenated blood from right atrium and oxygenates it and deposits it to the left atrium is called the pulmonary circuit.
