Document Summary
Anterior of the eye is the area where the pupil, iris and cornea are. The posterior is where the optic nerve is. Closest to the center are the ganglion. Uid within a cell is called intracellular uid. Fluid that surrounds a cell is extracellular uid. Uid found in tissues is called interstitial uid. Extracellular and interstitial both refer to the uid outside the cells. However, if you are thinking about an entire tissue, it is more common to use interstitial uid. We talk about blood in terms of the whole tissue (whole blood) or its parts: Buffy coat (white blood cells-leukocytes; and platelets) Whole blood - plasma = formed elements (cells and cellular material in the blood) When we take it out of the body, we will often separate it and they will fall into three categories based on density: And the plasma, which is the least dense and most liquid.
