Question

Blood emptied into heart by vena cava sequentially passes through which valve ?

• A. Bicuspid valve aortic arch-semilunar valve-mitral valve-pulmonary semilunar valve
• B. Bicuspid valve-pulmonary semilunar valve – mitral valve-aortic arch-semilunar valve
• C. Tricuspid valve- pulmonary semilunar valve-bicuspid valve-aortic arch-semilunar valve
• D. Tricuspid valve- pulmonary semilunar valve-aortic arch-semilunar valve-mitral valve

Answer 1

The correct option is C Tricuspid valve- pulmonary semilunar valve-bicuspid valve-aortic arch-semilunar valve

Blood emptied into right atrium of heart by vena cava which passes through tricuspid valve.
The tricuspid valve is situated between the right atrium and right ventricle. Blood flows from right atrium into right ventricle through tricuspid valve.
The pulmonary valve is present between the right ventricle and the pulmonary artery. The mitral valve is present between the left atrium and left ventricle. The aortic valve is between the left ventricle and the aorta.
So, sequence of valve through which blood passes is- Tricuspid valve- pulmonary semilunar valve-bicuspid valve-aortic arch-semilunar valve.
