How fast does blood travel through the aorta?
10 mph
Do the veins rely on any other body part to work?
yes. they are situated close to muscles, when the muscles contract and relax this causes the blood to flow through them. blood is low pressure through veins therefore does not move fast, it relies on the muscle movement to move the blood through them. the valves prevent backflow of the blood.
Why veins have valves and arteries don't?
Arteries do not have valves because the heart provides the pressure needed to send blood through the system. Veins have valves because venous pressure is often not great enough (as the blood must overcome gravity and other forces) to return the blood to the heart.
How fast does blood travel?
Blood travels at three feet per second when it leaves the heart, but it slows down as it reaches smaller arteries and capillaries. Blood takes one minute to travel through the body.
How fast do red blood cells travel?
325mph
Where does sound travel fast through?

Why do veins have low blood pressure?
Fish have one circuit and two heart chambers in their circulatory system. Blood collects in the atrium and moves to the ventricle where it is pumped first to the gills to collect oxygen, then to the body to deliver the oxygen to tissues. Since the blood does not return to the heart after moving through the gills, it has low pressure as it moves through the body.
Is the blood flowing through capillaries going fast or slow?
Fast
What material does sound travel fast through?
Solids
How fast travel sound through water?

How does the blood pumped from the heart to the rest of the body and back again?
The heart sends deoxygenated blood to the lungs, via the pulmonary arteries - thus this system is called the pulmonary circuit De-oxygenated blood flows from right ventricle of heart to lungs through two pulmonary arteries for oxygenation. After oxygenation the blood now travels through the pulmonary veins to left auricle of heart. Two pulmonary veins from each lung reach the heart making a total of four pulmonary veins. This circulation of blood to and from lungs is called pulmonary circulation. The pulmonary vein is thus the only vein which carries oxygenated blood and pulmonary artery in the same way the only artery to carry deoxygenated blood.
How fast does information travel through the nervous system?
