The functions of blood in the human body include:

  1. Transports oxygen, nutrients, wastes, hormones: Blood is responsible for transporting essential substances such as oxygen from the lungs to the tissues, nutrients from the digestive tract to cells, and waste products from cells to excretory organs. It also carries hormones from glands to target organs.

  2. Defends the body against pathogens: Blood contains white blood cells and antibodies that are crucial for the immune response, helping to protect the body against infections and diseases.

  3. Defends the body against blood loss: Blood contains platelets and clotting factors that are essential for the coagulation process, which helps to prevent excessive blood loss when injuries occur.

  4. Plays an important role in homeostasis by regulating body temperature: Blood helps to regulate body temperature by distributing heat throughout the body and adjusting the flow to the skin's surface to release or conserve heat.

The other options are not functions of blood:

  • Produces heat: Blood does not produce heat; it helps in the distribution of heat generated by metabolic processes in the body.

  • Produces hormones: Blood does not produce hormones; it transports them. Hormones are produced by endocrine glands.

  • Excretes waste such as carbon dioxide: Blood transports carbon dioxide to the lungs for exhalation but does not excrete it directly.

In summary, the correct functions of blood include transporting substances, defending against pathogens and blood loss, and regulating body temperature.
