Blood stabilizes the body temperature when it consumes the heat that is released by active skeletal muscles and quickly resends it to other tissues. For example if the temperature if the body is high, the heat will be released through skin, sweating for instance. When the body temperature is low, the warm blood is directed to the brain and to other temperature sensitive organs (Martini, 2012, p. 653). The blood defends the body against Pathogens and toxins by providing the body with white blood cells and antibodies. The white blood cells migrate into tissues that are specifically designed to fight infections and get rid of any debris. Pathogens however are proteins that attack organisms. The blood also transports gases, nutrients, hormones and metabolic wastes. The blood is able to transport gases to the lungs, receives its nutrients from the digestive tract and transports wastes from tissue cells into the kidneys to be ejected.
