Answer:
Pulmonary circuit
Explanation:
Pulmonary circuit of blood circulation serves to carry the deoxygenated blood from the right ventricle of the heart to the lungs and then returns the oxygenated blood from the lungs to the left atrium of the heart. The pulmonary trunk carries the deoxygenated blood from the right ventricle to the lungs.
The right pulmonary artery and the left pulmonary artery of the pulmonary trunk carry the blood to the right and left lung respectively. After the gaseous exchange, the pulmonary capillaries unite to form venules and finally the pulmonary veins which in turn carry the oxygenated blood to the left atrium.
