First the deoxygenated blood enters the heart through the superior vena cava, then it goes through the tricuspid valve into the right ventricle. From there it goes through the pulmonary valve and the pulmonary artery into the lungs to get oxygenated. Once it's oxygenated, it comes back from the lungs and goes through the left atrium and enters the left ventricle though mirtal valve. From there it leaves the heart through the aorta and is transported through the rest of the body.

Which side does deoxygenated blood go to?

Back to the lungs via veins to be re-oxygenated


What is the function of the pulmonary artery?

To carry deoxygenated blood from the right ventricle of the heart to the lungs where it will be reoxygenated.


What blood does pulmonary vein carry?

Oxygenated blood from the lungs to the heart. This is unusual as almost all veins carry deoxygenated blood.


Where does blood go next after passing the right ventricle?

The right ventricle empties into the pulmonary arteries which carry the deoxygenated blood to the lungs to be re-oxygenated.


When deoxygenated blood leaves the heart where does it go?

Freshly oxygenated blood from the lungs goes directly to the heart. From there, approximately 50% of the blood goes directly to the brain and head while the other half is distributed to the rest of the body.


Where is the blood oxgenated?

veins (exept pulmonary vein, wich brings back oxygenated blood from the lungs to the heart, were it will be pumped in the body) en route back to the heart to get pumped to the lungs were it will be reoxygenated and then go into the arteries to deliver oxygen back to the organs. You can also find deoxygenated blood int the pulmonary artery, since it brings the deoxygenated blood from the heart to the lungs. 60% of the blood is found in the veins. Therefore most of the blood is deoxygenated.


What is the sequence of oxygen carbon dioxide and the blood stream?

When we inhale, the blood in the capillaries in our lungs will get the oxygen (the blood will be oxygenated) and it will go to the heart, first in the left atrium,mitral valve,left ventricle and to the aortic valve that will transport it to the different parts of body. Then, when the blood is deoxygenated, it will go to the inferior vena cava, right atrium,tricuspid valve,right ventricle, and pulmonary veins and the deoxygenated blood will go to the capillaries in our lungs and transport the carbon dioxide to the alveoli and we exhale it.


Do veins carry oxygenated blood or deoxygenated blood?

Deoxygenated With the exception of the pulmonary vessels, veins carry deoxygenated blood; arteries carry oxygenated blood.


What returns oxygen-poor blood to the heart?

Yes, the blood from the lungs is rich in oxygen. Since you breathe in oxygen and nutrients through your nose/mouth to the lungs, the oxygen and nutrients are absorbed in the lungs and go through the blood stream into the heart


What do human arteries do?

Arteries are the major blood vessels that carry blood away from the heart. Except for the pulmonary arteries which go from the atrium to the lungs, arteries carry oxygenated blood. The veins bring blood back into the heart. Except for the pulmonary veins that connect the lungs to the ventricles of the heart, veins carry deoxygenated blood.

Why are pulmonary arteries called arteries?

It is called a artery because arteries are vessels that stem from the heart and deliver blood to the organs. The pulmonary artery is still an artery, even though it carries deoxygenated blood, because it is coming from the heart to the lungs.Veins collect blood from organs and transport it back to the heart. Veins do not have a pulsating pressure, while arteries do, because arteries are still feeling the rhythmic push from the heart.Arteries carry blood away from the heart. They usually contain oxygen rich blood, except for the pulmonary artery, which carries deoxygenated blood to the lungs.Veins carry blood to the heart. They usually contain deoxygenated blood, but the pulmonary veins carry oxygenated blood (because they're coming from the lungs).
