They prevent backflow of blood back into the Left and Right Ventricles
the blood comes in the through the superior and inferior vena cava. it then passes through the right atrium and is pushed through by the bicuspid valves. it enters the right ventricles and exits the heart through the right semi lunar valves and the pulmonary arteries and into the lungs. it is then brought back in through the pulmonary veins and passes through the left atrium. it is pushed through by the bicuspid valves and into the left atrimu and exits through the left semi lunar valves and out through the aorta to the rest of the body.
what takes place is that zekrom and reshiram start to fight and then kyurem joins in the fight hence black and white and in between there is gray just like truth and ideals and bouandry's of the fight between pokemon.
The valves between the chambers of the heart are there to prevent the backflow of blood between the atria and the ventricles. (Bicuspid and Tricuspid Valves) and to prevent the backflow of blood between the Aorta and the ventricle on the left side and the ventricle and the pulmonary artery on the right side. (Semi lunar valves) If there are problems with valves, this can lead to varicous veins.
You can breed a Lunar Eclipse dragon using the following combinations: Lunar Eclipse and Lunar Eclipse, Lunar Eclipse and Solstice, Equinox and Lunar Eclipse, Blue Moon and Lunar Eclipse, Lunar Eclipse and Solar Eclipse, Lunar Eclipse and Moon, and Lunar Eclipse and Sun.
the semi lunar valves stop the blood flowing the wrong way !
There are 3
semi-lunar valves
Semilunar valves are open when the blood is being pumped. The AV valves are closed when the semilunar valves are open.
Open so the ventricle can receive more blood to pump.
The semi-lunar valves
lub dub lub is when the av valves close and dub is when the semi lunar valves close
bicuspid valve tricuspid valve semi lunar valve
they are found at the entrance of the main aorta and the pulmonary artery
semi lunar valves
you should have listened to your teacher when she was explaining kiddo.
your semi lunar valves stop slop from entering your left aorta and your lunar valves stop crud from entering your right ventricle. this is the purpose of your valves. but this is different in dogs as your septum helps fight against testicular torsion.
