Verified step by step guidance

Step 1: Begin by reviewing the major functions of blood in the human body. Blood is a vital fluid that performs several essential roles, including transportation, regulation, and protection.

Step 2: Understand the transportation function of blood. Blood transports oxygen from the lungs to tissues, nutrients from the digestive system to cells, and waste products to organs for excretion. This aligns with the option 'Transporting oxygen and nutrients to tissues.'

Step 3: Examine the regulatory function of blood. Blood helps regulate body temperature by redistributing heat throughout the body and maintaining homeostasis. This corresponds to the option 'Regulating body temperature.'

Step 4: Explore the protective function of blood. Blood contains white blood cells and antibodies that help protect the body against infection. This matches the option 'Protecting the body against infection.'

Step 5: Evaluate the option 'Producing hormones for endocrine signaling.' Blood does not produce hormones; instead, it transports hormones produced by endocrine glands to target tissues. Therefore, this is NOT a major function of blood.
