The circulatory system and immune system serve the same, yet complementary purpose, to keep the entire body alive. The circulatory system does this by delivering oxygen from the lungs to every organ and cell in the body. The immune system does this by consuming foreign substances before they can damage the body. The connection between the circulatory system and immune system lies in the fact that the immune system travels through the entire body, inside the circulatory system. The circulatory system has three major components: the heart, the lungs, and blood vessels.
Organs of the Immune System: significance of the lymphatic and circulatory systems. Many organs are involved in the immune response like the lymphatic system, bone marrow, the spleen, and the thymus.Bone marrow, the spongy tissue inside of the bone, is the birthing ground for white blood cells. cells mature in the bone marrow, but T cells travel to the thymus to grow. Just like blood travels through veins and arteries, the cells of the immune system have their own transportation system where they perform many functions. This is called the lymphatic system.
