ANATOMY

Detailed explanation-1: -Plasma serves as a transport medium for delivering nutrients to the cells of the various organs of the body and for transporting waste products derived from cellular metabolism to the kidneys, liver, and lungs for excretion.

Detailed explanation-2: -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.

Detailed explanation-3: -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.

Detailed explanation-4: -Digested food:-Plasma carries digested food to respiring cells for energy. Urea:-Urea is a waste substance and is carried by plasma to the kidneys for excretion.
