The movement of water and electrolytes is primarily regulated between fluid compartments by hydrostatic pressure and osmotic pressure.
The kidneys primarily regulate the movement of water and electrolytes between fluid compartments in the body. They remove waste products, control blood pressure, and maintain electrolyte balance by filtering blood and producing urine.
Sodium. Sodium is a major electrolyte that helps regulate water balance in the body by controlling fluid movement between compartments. It plays a key role in maintaining proper hydration levels and overall electrolyte balance.
Osmotic pressure is the main force that drives fluid movement from intracellular to extracellular spaces. It is influenced by the concentration of solutes inside and outside the cell. Additionally, hydrostatic pressure gradients across cell membranes can also contribute to fluid movement between intracellular and extracellular compartments.
Transcellular fluid includes the water and electrolytes within the body's specialized compartments, such as cerebrospinal fluid, synovial fluid, and intraocular fluid. It is separate from the more generalized extracellular and intracellular fluid compartments.
Interstitial compartments refer to the spaces or areas between cells in tissues where interstitial fluid circulates. This fluid contains nutrients, hormones, and waste products that are exchanged between cells and blood vessels. Interstitial compartments play a crucial role in maintaining the overall homeostasis of the body.

Sodium (Na+) is the most significant solute in determining the distribution of water among fluid compartments through osmosis. It plays a critical role in regulating fluid balance in the body by influencing the movement of water between cells and the extracellular fluid compartments.
Cell membranes separate the intracellular and extracellular fluid compartments. The intracellular fluid is contained within the cells, while the extracellular fluid surrounds the cells. Transport proteins in the cell membrane regulate the movement of substances between these compartments.
Fluid flow between body compartments is determined by a combination of factors such as hydrostatic pressure, osmotic pressure, and permeability of the membrane separating the compartments. These factors influence the movement of water and solutes to maintain fluid balance and osmolarity in different parts of the body.
Sodium. Sodium is a major electrolyte that helps regulate water balance in the body by controlling fluid movement between compartments. It plays a key role in maintaining proper hydration levels and overall electrolyte balance.
The direction of water movement between fluid compartments is determined by the concentration of solutes in each compartment and the relative difference in their osmolarity. Water will move from an area of lower solute concentration to an area of higher solute concentration to try to equalize the concentrations on both sides of a membrane barrier. This process is known as osmosis.
Interstitial fluid, plasma, and transcellular fluid.
Osmotic pressure is the main force that drives fluid movement from intracellular to extracellular spaces. It is influenced by the concentration of solutes inside and outside the cell. Additionally, hydrostatic pressure gradients across cell membranes can also contribute to fluid movement between intracellular and extracellular compartments.
The plasma membrane of cells separates the interstitial fluid (between cells) from the blood plasma. In addition, the blood vessels' walls, composed of endothelial cells, create a physical barrier between the blood and the surrounding interstitial fluid.
Water moves between the intracellular fluid (ICF) and extracellular fluid (ECF) to maintain osmotic balance in the body. This movement occurs through processes such as osmosis and involves the regulation of electrolytes and proteins to ensure the right balance of water inside and outside cells. Hormones like antidiuretic hormone (ADH) also play a role in controlling the movement of water between these compartments.
