Verified step by step guidance

Identify the primary functions of blood in the human body. Blood is responsible for several critical functions, including transportation, regulation, and protection.

Focus on the transportation function of blood. Blood transports oxygen from the lungs to the cells of the body and carries carbon dioxide from the cells back to the lungs for exhalation.

Consider the role of blood in nutrient transport. Blood carries nutrients absorbed from the digestive tract to cells throughout the body, providing the necessary components for energy and growth.

Evaluate the other options provided: Generating electrical impulses is primarily a function of the nervous system, storing calcium is a function of bones, and producing hormones is a function of endocrine glands.

Conclude that the primary function of blood, among the options given, is transporting oxygen and nutrients to cells, as this is a fundamental role of the circulatory system in maintaining homeostasis.
