Left Atrium
The structure that sticks out from the cells surface and allows it to move is known as cilia. Some cells also use flagellum to move.

The aortic valve allows the blood to leave the left ventricle.
No, the tricuspid valve permits one-way blood flow from the right atrium to the right ventricle. There is no valve or natural opening that allows blood flow from the right atrium to the left atrium.
the left atrium is above the left ventricle. the blood which has been oxygenated from the lungs due to the gas exchange between the alveoli and capillaries comes here from the pulmonary artery this blood then gets sent to the left ventricle through the bicuspid valve this stops the backflow of blood but it allows the blood to go to the left ventricle but does not allow the blood to go back

The aortic valve allows the blood to leave the left ventricle.
structure allows function. for example, you can walk because you have a skeleton; the structure of your skeleton allows the function of walking.
With the exception of crocodilians, reptiles and amphibians have only two chambers in their hearts: two atria and a single ventricle. The single ventricle allows oxygenated blood to mix with deoxygenated blood.
What structure allows only certain things to pass in And out of the cell
The structure that allows water into and out of the water vascular system is called the madreporite.
An incompetent valve allows backflow of blood.
The structure is the cell membrane.
