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

Identify that blood plays a 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 as needed.

Note that producing hormones is not a function of blood. Hormones are produced by endocrine glands and then transported by the blood to target organs and tissues.
