Answer 2

Hii There!!

Pulmonary Circulation:-
◆starts from right ventricle, which sends the blood into the pulmonary artery to reach lungs. From lungs, oxygenated blood returns to the left auricle of the heart through pulmonary veins.
◆Thus, pulmonary circulation starts from right ventricle and end at left auricle of the heart.



Double Circulation:- The blood comes twice to the heart in each cardaic cycle, means from body to body . The blood comes two times in the Heart.
