How to make a model of a circulatory system?

Question

it should be made of thermocoles [optional] but just write to me how to make it.

Answer 1

Cut the bottom out of a plastic bottle with scissors. Be careful with the sharp edges. The bottom of the bottle will be used as the valve. Cut the middle of the bottom three ways to represent the tricuspid valve (Fig. 1). Invert the valve and place it in the lower portion of the bottle. Cut three feet and two feet section of the 7/8 inch tubing. Cut 7 one-foot section of the 5/16 inch tubing. The three feet section represents the arteries. The two feet section represents the veins and the 7 one foot sections represent the capillaries. Place some glue around the opening of the bottle, insert the three feet tube into the bottle. Arrange the 7 one foot sections as shown below (Fig. 2). Tie the tubes together and superglue the tubes to each other two inches at the top and bottom. Remove the ties when the glue dries. Carefully insert the top glued tubes into the artery and bottom into the veins. Mix the syrup and water in a 1:3 ratio to make four liters of blood. Place the blood into the model and record the data.
