Circulatory system
It is one system that works together, but it is a double system. It is made up of the Pulmonary Circulatory System, which carries blood to the lungs to swap deoxygenated blood for oxygenated blood and the Systemic Circulatory System, which carries blood from the heart to the rest of the body. This is why the heart has four chambers - because it is a double system.
The blood travels through the human body by way of the circulatory system. The circulatory system is made up of the heart, the lungs, and blood vessels (arteries, veins, and capillaries.)
Human blood is a tissue. It is made of different cells working together for a common function.
