Tendons are the structures that prevents valves from turning inside-out.
The valve between your RIGHT atrium and ventricle is called the TRICUSPID VALVUE and the valve between your LEFT atrium and ventricle is called the MITRAL or BICUSPID VALVUE.
The semi lunar valves control the flow of blood coming back into the Right Atrium.
Although sheep and human organs are similar in number, name, and structure, the organs found in sheep are smaller and somewhat different than those of their human counterparts. In spite of the similarities, one cannot exchange organs between the two species.
To ensure that the AV valves do not evert (turn inside-out), they are attached to (anchored by) small papillary muscles by tough tendons called the cordae tendineae or chordae tendineae cordis.

The valves in the veins
In the heart/arteries, the Aortic valve prevents blood from flowing backwards. In the systemic veins, eustachean valves prevent the backwards flow of blood.

veins contain valves that prevents blood flowing backwards between heartbeats.There are valves in the veins that stop the blood from flowing backwards.
