the body
Contractions and relaxation of heart chambers make the blood flow inside the tubes or blood vessel.

yes :)
The heart pumps blood rapidly, letting it flow through the body.
blood flows into the veins quiet slowly as they are much wider compared to the flow of blood in the arteries which are rather narrow.because of the low pressure of blood on the flow inside the veins there are great possibilities that the blood is likely to flow backwards which may cause complications in the flow of blood.to prevent this from happening the veins contain valves that stop the back flow of blood
Clots inside the blood vessels block the flow of blood to major organs and cause heart attacks and strokes.
when the blood flow is disturbed it stops heat travelling
The valves in the veins
it depends upon the size of blood vessels,some are small in size and some are big,in this situation there is alteration of blood flow,so the speed of blood inside the vessels wont be constant
Blood doesn't clot inside of the body because it is all working together. Some blood may clot in the body, which causes blood clots. This is caused by blockages. Blood that doesn't clot has a wide flow.
The blood in veins is not under direct pressure from the heart. It has little valves inside to prevent blood from flowing backwards away from the heart. These valves inside the veins prevent the backflow of blood in veins. They encourage the one-directional flow of blood to the heart.
Heart valves help prevent blood from flowing backwards through the chambers of the heart. They open only one way to allow blood to flow through to the next chamber, and close against flow of blood from the other directon.
