PATHOLOGY

Detailed explanation-1: -Plasma carries water, salts and enzymes. The main role of plasma is to take nutrients, hormones, and proteins to the parts of the body that need it. Cells also put their waste products into the plasma. The plasma then helps remove this waste from the body.

Detailed explanation-2: -Ions make up only about 1% by weight of human plasma. However, they are the major contributors to plasma molarity, since their molecular weights are much less than those of proteins. Thus, ions are important in preventing blood cells from bursting by taking up excess water in osmosis.
