know the components of blood plasma

percentage of **water** in blood plasma

92%

percentage of **plasma protein** in blood plasma

7%

percentage of remaining in blood plasma

1% - everything else

water:

* a pale yellow sticky fluid that contains over 100 different dissolved items such as nutrients, gases hormones, wastes, ions, and proteins
* similar to tissue fluid but more proteins

plasma protein

* made by liver
* albumin, globulin, fibrinogen

albunin (plasma protein)

acts as a **carrier** to move lipids, hormones, and ions through circulation

* it is an important blood buffer to main proper pH
* helps maintain the correct plasma osmotic pressure which keeps water in bloodstream

globulins (plasma protein)

acts as **transport** proteins that bind to hydrophobic molecules

* act as antibodies to fight infection

fibronogen (plasma protein)

**clotting protein** - helps form fibrin threads for blood clotting

everything else - (remaining in blood plasma)

* organic wastes (lactic acid, urea, creatine, biliruben)
* organic nutrients (glucose, carbohydrates, amino acids, triglycerides)
* electrolytes (Na+, K+, Ca2+, CI-, HCO3-)
* respiratory gases → O2 & CO2
* hormones
