What solutes can be found in plasma?

Plasma, the liquid component of blood, contains a variety of solutes that play crucial roles in maintaining physiological functions. The correct answer highlights that plasma is composed of proteins, electrolytes, and waste products.

Proteins in plasma include albumin, globulins, and fibrinogen, which are essential for functions such as maintaining osmotic pressure, immune responses, and blood clotting. Electrolytes, such as sodium, potassium, calcium, and chloride, are vital for maintaining fluid balance, nerve function, and muscle contractions. Waste products like urea, creatinine, and bilirubin are produced from cellular metabolism and are transported in the plasma to be excreted by the kidneys or the liver.

This broad range of solutes is crucial for the overall homeostasis of the body, as they contribute to various physiological processes, including nutrient transport, pH balance, and waste removal. Other options provided do not encompass the comprehensive range of solutes present in plasma, limiting the understanding of its complex composition and functions within the body.
