After blood leaves the left ventricle, it goes through the aortic valve to be pumped throughout the body.
pulmonary trunk of the heart
if blood entering the heart gets mixed with blood leaving the heart the the blood leaving the heart will get poluted. the blood entering the heart is poluted when it enters the heart, the heart cleans it up; so when the blood leaves the heart it is clean so if it gets polluted the person may get sick and this leads to his/her death.
The pulmonary artery, which takes deoxygenated blood from the right side of the heart to the lung to be reoxygenated. The pulmonary vein then carries oxygenated blood back to the left side of the heart to be pumped back to the rest of the body.
From the vena cava, blood travels into the right atrium, then the right ventricle. The right ventricle pumps the blood through the pulmonary arteries to the lungs. The pulmonary vein carries the oxygenated blood back to the left atrium. The blood flows from the left atrium into the left ventricle which pumps the blood through the aorta and to the rest of the body.
Four main blood vessels enter/exit the heart: two veins and two arteries. Oxygenated blood enters the left ventricle through the pulmonary vein. This same blood is then pumped out of the left atrium via the aorta. Meanwhile, de-oxygenated blood enters the heart in the vena cava; before leaving through the pulmonary artery.
As blood leaves the heart it travels through the arteries. The first one will be either the pulmonary artery (for blood leaving the right side of the heart) or the aorta (for blood leaving the left side of the heart).
pulmonary trunk of the heart
The pulmonary arteries leave the right ventricle to travel to the heart, so carry deunoxygenated blood. The name "arteries" is used because the vessels are leaving the heart.The pulmonary veins, conversely, are coming back into the heart, so are veins, but they are carrying oxygenated blood.
The blood leaving the kidneys have most of the waste products removed. The kidneys do use some of the oxygen in the blood, but only a tiny amount, so the outflow is essentially clean arterial blood.
The two atria (right atrium and left atrium) of the heart travel (force blood) to the ventricles (right ventricle and left ventricle), respectively.

Firstly blood returns to the heart by the continuous pumping of the heart itself as blood is continously pushed from the chambers of the heart. Secondly the veins have valves which prevent the blood from flowing backwards. Thirdly the contraction of the muscles help to push the blood back to the heart. Hope this helps.
the blood in the right side is de oxginated blood
Blood enters the heart through the right atrium, then flows into the right ventricle. From there, it is pumped to the lungs to pick up oxygen. Oxygenated blood returns to the heart through the left atrium, then moves into the left ventricle. Finally, the left ventricle pumps the oxygen-rich blood out to the rest of the body.
2 valves: pulmonary valve- blood leaving from the right ventricle passes through it towards the lungs; aortic valve- blood leaving from the left ventricle passes through it to the body (by way of the aorta)
After leaving the right ventricle, blood goes into the pulmonary artery. This vessel carries the blood to the lungs, where gas exchange occurs.
