Detailed explanation-1: -Two distinct fluids move through the circulatory system: blood and lymph. Blood carries oxygen and nutrients to the body’s cells, and carries waste materials away. Blood also carries hormones, which control body processes, and antibodies, to fight invading germs.

Detailed explanation-2: -The immune system is made up of two parts: the innate, (general) immune system and the adaptive (specialized) immune system. These two systems work closely together and take on different tasks.

Detailed explanation-3: -Your immune system relies on specialized cells to fight off threats to your health. One of the most important ways your circulatory system supports your immune system is by carrying immune cells to their destinations. Without your blood vessels and arteries, these important cells could not do their job correctly.

Detailed explanation-4: -The immune system is like a small police force that constantly patrols every organ and tissue in your body. It works closely with the circulatory system for transportation needs and the lymphatic system for production of lymphocytes.
