sodium transport
Sodium transport refers to the movement of sodium ions across cell membranes, which is essential for various body functions like nerve signaling and maintaining fluid balance. Cells use specialized proteins called sodium channels and pumps to move sodium in and out, often using energy in the process. For example, sodium enters nerve cells to help transmit signals, while the sodium-potassium pump moves sodium out and potassium in to keep the cell's environment stable. This regulated transport is vital for overall health and proper functioning of tissues.
