Cuspid valves are right and left atrioventricular (AV) valves.
yes
They prevent blood from backing up, or going backwards, into the atria.
Blood veins have valves that prevent blood from flowing backwards.
That is so true! In fact it is the function of the heart valves.
Valves.
Chordae tendineae - attached to the valves between both atria and ventricles... these structures are attached to papillary muscles in the bottom of the ventricles. these contract when the valves contract, this keeps the blood from going back up into the atria.
Valves are needed to prevent blood flowing backwards into the heart.
Heart valves help prevent blood from flowing backwards through the chambers of the heart. They open only one way to allow blood to flow through to the next chamber, and close against flow of blood from the other directon.
Veins have valves which stop the blood from flowing backwards
yes they are, only separated by small valves,which are there to prevent the backwards flow of blood
Atrioventricular valves prevent backwards flow of blood inside the heart, i.e. flow from the ventricles back to the atria. Semilunar valves prevent backwards flow of blood into the heart from the aorta (left ventricle) or the pulmonary arteries (right ventricle).
