Final answer:
The term for various substances in the blood, including gases, plasma proteins, hormones, wastes, nutrients, and electrolytes is plasma. It is essential for material transport and homeostatic regulation in the body.
Step-by-step explanation:
The term for gases, plasma proteins, hormones, wastes, nutrients, and electrolytes in the blood is plasma. Blood plasma is the liquid component of blood, of which more than 90 percent is water. The remainder consists largely of plasma proteins, including albumin, globulins, and fibrinogen, as well as other dissolved solutes like glucose, lipids, electrolytes, and dissolved gases. This complex mixture plays a critical role in transporting materials throughout the body, including blood cells, and is essential for maintaining homeostatic regulation of pH, temperature, and other internal conditions.
