Verified step by step guidance

Understand the primary functions of blood in the human body. Blood is a vital fluid that performs several key roles essential for maintaining homeostasis.

Recognize that one of the main functions of blood is to protect the body against infections. This is achieved through the immune system components present in the blood, such as white blood cells and antibodies.

Acknowledge that blood plays a crucial role in regulating body temperature. It does this by distributing heat throughout the body and adjusting blood flow to the skin to release or conserve heat.

Identify that blood is responsible for transporting oxygen and nutrients to cells. Red blood cells carry oxygen from the lungs to the rest of the body, while plasma transports nutrients absorbed from the digestive tract.

Clarify that producing hormones is not a function of blood. Hormones are produced by endocrine glands and are transported by the blood to target organs, but the production itself is not a function of blood.
