Question

Help please.. Will fan and give medal.

Answer 1

Consider the roles of valves and blood vessel walls in moving blood through the body. If you were given a piece of flexible tubing and a small piece of plastic, how might you design a simple model that would simulate those roles?

Answer 2

The plastic probably need to be fixed at the end of the flexible tubing, because the valves control the direction of blood flow..

Answer 3

the tube is like a blood vessel, and the plastic is just like the valves. The plastic piece in the tube opens when the water flows in correct direction and close when water backflows
