Oxygenated blood flows from the lungs to the left atrium contractions (heart muscle) cause the blood to leave the atrium and enter the left ventricle. Further contraction causes the blood to leave the atrium and enter the aorta.

What does the blood travel through?
arteries and veins
How does the capacity of the blood vessels change?
The largest arteries are closest to the heart, passing blood to smaller arteries, and then again to even smaller arteries, until finally passing blood in a single file line through the capillaries which allow the nutrients and oxygen to seep out and nourish the organs and tissue.
Do arteries pump blood to your body?
No the heart pumps the blood but it does pump the blood through the arteries.
Why blood is transfused only through vein but not through arteries?
Because the arteries wouldn't be able to have blood flow through your body unlike arteries veins are through out your whole body so they can transport blood through your whole body, veins keep your blood circulating
Why are deposits inside arteries a problem for the human circulatory system?
Because they restrict the amount of blood passing through the arteries. If there are fatty deposits around the edges of the artery or vein, then there is less room for the blood to get through. This would mean that less blood would get through with each heart beat, and could cause more serious injuries - for example, a heart attack.
How does your blood travel through you heart?
through arteries
What structures in the body enable blood flow?
heart! ! the pulses through both ventricles and atria passing through the valves like the tricuspid make the pulses. the aorta and other arteries bring the blood to the body organs.
What forces the blood through the arteries?
Blood is pumped by the heart.
What two ways are veins structurally different from arteries?
blood travels away from the heart through arteries and blood travels to the heart through the veins
What passes through the arteries?
oxygenated blood
What happens in the arteries?
The blood runs through them
Where does blood travel after the right auricle?
It travels to the right ventricle passing through the tricuspid valve. Then it travels to the lungs via pulmonary arteries. The oxygenated blood from the lungs returns to the heart (into the left auricle). From the left auricle the blood travels to the left ventricle. The left ventricle pumps it to aorta. The blood travels through the arteries and veins, then it returns to the right auricle of heart.
