Function: The Circulatory System helps get the oxygen and blood you need to your body, It also helps get blood to your heart. Your Veins carry blood towards your heart while. And arteries carry blood away to transfer it somewhere else.  Arteries and veins are called blood vessels.  Blood vessels carry blood throughout your whole body.  Oxygen is required through your body so the blood transports oxygen by us consuming oxygen when we breathe in and then the heart pumps blood into your lungs so it can pick up the oxygen. Once that's happened the oxygenated blood leaves and separates throughout your body.

Organs:
Heart - The heart pumps blood for the circulatory system to bring around the body. This organ has 4 different chambers. The heart never stops beating and pumping blood. The heart is the center of the circulatory system because thats where bloods starts to be pumped throughout the body.
Lung - Lungs are responsible for bringing oxygen to the body. The red blood cells traveling from the heart to the lungs pick up the oxygen. This happens so that the oxygenated red blood cells can bring oxygen and blood to the whole body.
Veins - The Veins are responsible for taking blood to the heart. So the blood returns to the heart and the circulatory system continues. This is the opposite of what the arteries do rather than taking the blood away from the heart.
Arteries - Arteries bring blood away from the heart. Rather than taking it to the heart like the veins the arteries take the blood and oxygenated red blood cells throughout the whole body. Arteries are responsible for the spread of blood and oxygen throughout the cells.
Capillaries - These are responsible for transferring dissolved gases and compounds. The capillaries are like little vessels. The walls of the capillaries are thin and small so that nutrients,carbon dioxide,glucose and waste products.

Interaction With Other Systems:
The Circulatory system works with the respiratory system because when you breathe in the oxygen you get oxygen in your lungs so that you will be able to have the red blood cells absorb the oxygen. And when the oxygen gets into the red blood cells you get oxygenated red blood cell which goes through the body delivering blood and oxygen.

Analogy:
My analogy is a water slide because its like the Circulatory system. Its like the Circulatory system because the water is continuously flowing like the heart and its blood and the people who get on act as the oxygenated blood cells as they travel through the maze of tunnels to the end of the slide. After the end of the slide it leads to a ladder where the kid can chose to go again. So its a continuous process. And then once another kid goes down the slide its as if more oxygenated blood cells are being transported.

Structure And Function:
The heart is the center of all the circulatory system. Because the heart is what pumps blood into the lungs so the red blood cells can absorb the oxygen and when this happened the red blood cells will become oxygenated. Once they are oxygenated they will take a long route through the body by travel of Veins and Arteries. Then it travels trhough the body spreading blood and oxygen. If the heart stop beating or stops doing its funtioni it could mean the end of the human and the system.
