Body Fluids and Fluid Compartments | Anatomy and Physiology II. If that capillary membrane is permeable to the contrast agent, it will rapidly leave the vessel and diffuse into the perivascular interstitial fluid space.The image above shows the composition of the cell membrane that separates the extracellular fluid of a cell from the intracellular fluid (cytoplasm). sodium moves out of the cell and potassium is pumped in) and maintain the gradients inside and outside the cell. The pumps are powered by adenosine triphosphate (ATP) to provide the energy to move the ions against their concentration gradients (i.e. The infusion has reduced its speed or it has. The dressing applied over the IV site is either damp or wet. The skin around the IV site is blanche and cool. Intense pain is experienced by the patient. While water moves passively via osmosis, sodium and potassium ions move in and out of cells using active transport ion pumps. These are the most common signs and symptoms of the IV infiltration: Inflammation at or near the site of insertion. The plasma has high concentrations of sodium, chloride, and bicarbonate, but lower levels of protein as compared to the ICF. The ICF has higher amounts of potassium, phosphate, magnesium, and protein compared to the ECF. The Movement of Solutes Between Compartments In mammals, milk is also considered an extracellular fluid. The balance consists of cerebrospinal fluid, lymph, the synovial fluid in the joints, pleural fluid in the pleural cavities (lungs), pericardial fluid around the heart, peritoneal fluid in the peritoneal cavity (abdomen), and the aqueous humor of the eye. The two main components of ECF are plasma and interstitial fluid (IF). ECFs are any body fluids that are not inside cells.
