Verified step by step guidance

Begin by identifying the major functions of blood in the human body. Blood is responsible for several critical functions, including transportation, regulation, and protection.

Consider the transportation function: Blood transports nutrients, gases (such as oxygen and carbon dioxide), hormones, and waste products throughout the body.

Next, examine the regulation function: Blood helps regulate body temperature by distributing heat throughout the body and maintaining homeostasis.

Then, look at the protection function: Blood plays a key role in protecting the body against infections through the immune system components, such as white blood cells and antibodies.

Finally, evaluate the synthesis of hormones: Hormone synthesis is primarily a function of endocrine glands, not blood. Blood transports hormones but does not synthesize them, making this option not a major function of blood.
