Anatomy and Physiology 2013-06-19T00:00:00Z They provide nutrients and other substances to neurons, regulate the concentrations of ions and chemicals in the extracellular fluid, and provide structural support for synapses. Biology for AP Courses 2022-06-09T00:00:00Z The water concentration of the body is monitored by osmoreceptors in the hypothalamus, which detect the concentration of electrolytes in the extracellular fluid. Biology for AP Courses 2022-06-09T00:00:00Z In an isotonic solution, the extracellular fluid has the same osmolarity as the cell. Concepts of Biology 2013-04-25T00:00:00Z Each separate substance in a medium, such as the extracellular fluid, has its own concentration gradient, independent of the concentration gradients of other materials.

Anatomy and Physiology 2013-06-19T00:00:00Z These carbohydrate complexes help the cell bind substances that the cell needs in the extracellular fluid. Biology for AP Courses 2022-06-09T00:00:00Z This allows the material that is needed by the cell to be removed from the extracellular fluid. Biology for AP Courses 2022-06-09T00:00:00Z If the concentration of solutes of the cell matches that of the extracellular fluid, there will be no net movement of water into or out of the cell. Concepts of Biology 2013-04-25T00:00:00Z Although receptor-mediated endocytosis is designed to bring specific substances that are normally found in the extracellular fluid into the cell, other substances may gain entry into the cell at the same site. Biology for AP Courses 2022-06-09T00:00:00Z These signals are sent by the endocrine organs, which secrete chemicals—the hormone—into the extracellular fluid. Anatomy and Physiology 2013-06-19T00:00:00Z In a hypotonic situation, the extracellular fluid has lower osmolarity than the fluid inside the cell, and water enters the cell. Biology for AP Courses 2022-06-09T00:00:00Z It also means that the extracellular fluid has a higher concentration of water in the solution than does the cell. Biology for AP Courses 2022-06-09T00:00:00Z In all vertebrate organisms this is a closed-loop system, in which the blood is largely separated from the body’s other extracellular fluid compartment, the interstitial fluid, which is the fluid bathing the cells. Concepts of Biology 2013-04-25T00:00:00Z Exocytosis is the opposite of the processes discussed above in that its purpose is to expel material from the cell into the extracellular fluid. Biology for AP Courses 2022-06-09T00:00:00Z Calcium ions are supplied by the SR in the fibers and by sequestration from the extracellular fluid through membrane indentations called calveoli. Anatomy and Physiology 2013-06-19T00:00:00Z If the osmolarity of the cell matches that of the extracellular fluid, there will be no net movement of water into or out of the cell, although water will still move in and out. Biology for AP Courses 2022-06-09T00:00:00Z Pinocytosis imports substances that the cell needs from the extracellular fluid. Biology for AP Courses 2022-06-09T00:00:00Z Conversly, if the plant is not watered, the extracellular fluid will become hypertonic, causing water to leave the cell. Biology for AP Courses 2022-06-09T00:00:00Z This literally means “cell drinking” and was named at a time when the assumption was that the cell was purposefully taking in extracellular fluid. Biology for AP Courses 2022-06-09T00:00:00Z Several synthetic drugs, including dopamine and isoproterenol, have been developed that mimic the effects of epinephrine and NE by stimulating the influx of calcium ions from the extracellular fluid. Anatomy and Physiology 2013-06-19T00:00:00Z Because the lipid tails are hydrophobic, they meet in the inner region of the membrane, excluding watery intracellular and extracellular fluid from this space. Anatomy and Physiology 2013-06-19T00:00:00Z In the case of carbon dioxide, as the concentration of CO2 in the blood increases, it readily diffuses across the blood-brain barrier, where it collects in the extracellular fluid.
