Water, ions, nutrients, and waste products constantly flow inside a cell to maintain its internal environment and support cellular processes. This movement occurs through various channels, transporters, and pumps on the cell membrane.
A nerve fiber becomes polarized when the resting potential of the membrane changes. It starts out with an unequal distribution of charges- the outside is more positive and the inside is less positive. (Sodium (Na+) is in a higher concentration on the outside of the membrane and Potassium (K+) is in a lower concentration on the inside of the membrane.) A stimulus changes the gradient- when more Na+ flows in, the resting potential changes and polarization occurs, allowing for an action potential to be propagated down the axon.

Water flows into a cell in a hypotonic environment because there is a higher concentration of solutes inside the cell than outside. This creates a concentration gradient that drives water into the cell through osmosis in an attempt to balance the concentrations on both sides of the cell membrane.
potassium The answer of potassium is dead wrong. Sodium is the electrolyte that flows into the cell to initiate depolarization. Potassium flows into the cell during repolarization.

It's mostly water, and it's called cytoplasm.

The Vatican is a state that exists inside the city of Rome and the river that flows through Rome is the Tiber.

* Oxygenated hemolymph (blood), coming from ctenidia, flows into heart's atria, * then it flows into heart's ventricle, which pumps the hemolymph into arteries, * from arteries, hemolymph flows into the hemocoel; * then it's caught again inside veins and brought directly into afferent ctenidial vessels or into accessory branchial hearts, which pump it inside ctenidia again, for oxygenation. Hemolymph flows also into the pericardium, the celomatic membrane wich contains the systemic heart, and, from it, hemolymph reaches and flows into the excretory ducts.
