Essay On Extracellular Fluid

Human cells are partially made up of liquids that are both inside and outside of our cells. The water inside the cell is called intracellular fluid (ICF) and makes up about 42% of the total body weight. On the other hand, extracellular fluids (ECF) usually denote all body fluid outside of the cells. In order to define which area the fluids are based, they are determined by its location to the cell membrane. For instance, if the fluids are found to be on the outside of the cell membrane, it would signify that we are viewing ECF. Just the opposite, if the fluids are on the inside, we can conclude it is ICF. If we were to look at these fluids in-depth, intracellular fluids are high in potassium and magnesium and low in sodium and chloride ions, whereas extracellular is mostly sodium and chloride.

Moreover, water moves inside and around the cell by osmotic pressure within each compartment and pulls fluid from one area to the other. The level of osmotic pressure remains approximately the same in ICF and ECF. Osmotic pressure can also be defined as the attraction of water to

Positive feedback, for example, increases the magnitude of a change and sends body chemistry further away from the set point. On the other hand, if any of the homeostatic values become disrupted, the body will begin to work towards the set point. This process, called negative feedback, counteracts a change that is or has occurred and brings a variable back to set point. One case is blood, which helps to regulate a variety of levels in the body to maintain homeostasis by ensuring that pH and electrolyte values are within normal parameters for proper cell functioning. Another instance would be when the pancreas secretes insulin in response to rising blood sugar. Survival depends on the body’s ability to maintain homeostasis and promoting good health will increase your chances to a long and healthy
