20 Points! Question:
Study the illustration. The small blue spheres represent water molecules.

In which direction will water molecules move across the membrane?

Water will move from A to B.

Water will move from B to A.

There will be no net movement of water.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

nucleus

would be most reasonable answer tbh
