The use of the valves in the heart is to have blood flow regularly through the heart. The valves pump blood out of the heart into the body.
the blood travel through blood vessels is the Artrium or atria. :-)
Because of the one-way valves.
The reason why we need we need valves in our heart is because the valves in our heart will open and close. When the valves in our heart open, they allow blood to go into places in our body where blood is needed. When the blood passes through, the valve closes. They regulate the blood flow.
yes
No the way the valves of the heart are set up causes the blood to move in one direction only.

Hormones travel In the blood because they need to travel in the body.
The valves stop the blood flowing backwards through the circulatory system.
I guess no because they prevent the backflow of blood.
They are called valves, or leaflet valves in the veins, that interlock to prevent backflow of the blood.
The aortic valve does that job.
