What is the primary function of plasma in blood?

The primary function of plasma in blood is indeed centered around transporting nutrients. Plasma is the liquid component of blood and constitutes about 55% of its volume. It serves as a medium for transporting a variety of substances throughout the body, including nutrients such as glucose, amino acids, and lipids that are essential for cellular metabolism and energy production.

In addition to nutrients, plasma also carries hormones, proteins, waste products, and other necessary substances, making it crucial for maintaining homeostasis. The presence of proteins like albumin in the plasma helps to maintain osmotic pressure, which is vital for proper fluid balance in the body.

While plasma plays a role in transporting nutrients, its functions extend beyond that, including the transport of hormones and waste products. However, the specific role in nutrient transport is a defining aspect of plasma's contribution to overall bodily functions.
