Zoology - Body Fluids and Circulation Question with Solution | TestHub

Double circulation in mammalian heart is as follows:

Superior and inferior vena cava bring deoxygenated blood$\to$right auricle → right ventricle → pulmonary artery → lungs → pulmonary vein → left auricle → left ventricle → aorta → body.
The valves present are tricuspid (between right auricle and ventricle), pulmonary semilunar valve (between right ventricle and pulmonary artery), bicuspid valve between left auricle and ventricle and aortic valve between left ventricle and aorta. In the anatomy of the heart the aortic valve is on the right side of bicuspid valve.
