Answer 2

2 veins viz. superior & inferior vena cavae open into ----------- Right atrium which is 1st chamber of the heart ---------(tricuspid valve) ------------ Right ventricle --------- (pulmonary semilunar valve) --------- Pulmonary artery ---------- lungs ----------- 4 pulmonary veins open into ---------- Left atrium -------------- (Bicuspid valve- also known as mitral valve) ------------ Left ventricle ----------- (aortic semilunar valve) ------------ Aorta.

P.S.- All valves are in brackets.
