Question

Which of the following would be the problem when tricuspid valve of human heart is ruptured? a)During ventricular systole, oxygenated blood will go back to left atrium b)Oxygenated and deoxygenated blood will be mixed c)During atrial systole, blood will not be poured into left ventricle d)During ventricular systole, deoxygenated blood will come back to the right atrium

Answer 1

Answer:

b). Oxygenated and de-oxygenated blood will be mixed

Answer 2

When the tricuspid valve of the human heart rupture, the deoxygenated blood will come back to the right atrium during ventricular systole. (Option d)

• The tricuspid valve is present on the right dorsal side of the human heart that is, between the right atrium and right ventricle.
• The role of this valve is to prevent the flow of blood backward,  from the ventricle to the auricle during systole or the contraction of the ventricle.
• So, if the valve ruptures, the blood will flow backward and this will de-oxygenated blood.
• Thus, this valve is a one-way valve.
• If the backflow of blood occurs for a prolonged period of time, it can lead to failure of the right heart.
