How they travel They then go into the pulmonary valve into the pulmonary artery to the lungs to pick up oxygen. From there they come back to the heart and are pumped into the aorta. While they are in the aorta the blood cells get split up in the arteries which take them to all different locations in the body.
What do they do When they get to all these different location, the arteries become smaller and smaller and turn into capillaries. Then they give their oxygen to all the organs in the body.
How they end their journey The red blood cells then head toward the heart in the capillaries which turn larger and larger and become arteries. From there they past through the liver and spleen. The liver and spleen get rid of all the blood cells that don’t work anymore. Then they get to the heart and do the it all over again. The heart The end
