yes it is in your blood. about 90% water
plasma
Interstitial fluid, plasma, and transcellular fluid.
Serum is a fluid similar to plasma but lacks plasma proteins like fibrinogen. Serum is obtained by allowing blood to clot, which results in the removal of fibrinogen and other clotting factors that are present in plasma.
Plasma, Lymph, interstitial Fluid and cerebrospinal fluid.
Extracellular fluid (extra-outside)
Blood plasma, extracellular fluid, and lymph are all components of the body's fluid compartments and are interconnected in the circulatory and lymphatic systems. Blood plasma is the liquid portion of blood, which circulates nutrients, gases, and waste. Extracellular fluid encompasses all fluid outside of cells, including interstitial fluid, which is derived from plasma and bathes cells. Lymph, formed from interstitial fluid, returns excess fluid and proteins to the bloodstream, thus maintaining fluid balance and facilitating immune responses.
Plasma is the fluid portion of unclotted blood. After blood clots, the fluid that remains is referred to as serum.
Plasma is considered a fluid because it can flow and change its shape, similar to liquids and gases. It is made up of charged particles, such as ions and electrons, that can move freely, giving plasma its fluid-like properties. Plasma is often referred to as the fourth state of matter, along with solids, liquids, and gases.
white blood cells
blood pressure in the cappilaries forces part of the plasma out through the walls .the fluid which escapes is not blood or neither plasma but is called tissue fluid by Rachael magro
Plasma is considered part of the extracellular fluid compartment, which also includes fluid within the interstitial spaces, lymph, and cerebrospinal fluid. Extracellular fluid is further classified into intravascular (plasma) and interstitial fluids.
The most widely distributed mineral in plasma and tissue fluid is sodium.
