Blood Flow through the Heart in 2 MINUTES
Neural Academy・2 minutes read
Veins carry deoxygenated blood back to the heart, while arteries carry oxygenated blood away from the heart. The heart's four chambers and valves ensure blood flows correctly from the body to the heart, then to the lungs for oxygenation, and back out to the rest of the body through the aorta.
Insights
- Veins carry blood to the heart, while arteries carry blood away from the heart, with deoxygenated blood represented by blue vessels and oxygenated blood by red vessels.
- The heart's four chambers and valves ensure blood flows correctly, with a complex system guiding blood from the body to the heart for oxygenation and then distributing it back through the aorta to all parts of the body.

Recent questions
What do veins and arteries do?
Veins carry blood to the heart, while arteries carry blood away from the heart.
How does blood flow through the heart?
Blood flows from the right atrium to the right ventricle, then to the lungs for oxygenation, returning to the left atrium and ventricle before being distributed to the body.
What is the function of the superior vena cava?
The superior vena cava receives blood from the head, neck, upper limbs, and chest, delivering it to the heart.
How many chambers and valves does the heart have?
The heart has four chambers and four valves to regulate blood flow.
What is the largest artery in the body?
The aorta is the largest artery in the body, distributing oxygenated blood to various parts of the body.

Blood Circulation Through Heart and Body
- Veins carry blood to the heart, while arteries carry blood away from the heart. Deoxygenated blood is represented by blue vessels, while red vessels contain oxygenated blood. The superior vena cava receives blood from the head, neck, upper limbs, and chest, while the inferior vena cava receives blood from the trunk, viscera, and lower limbs, both ending in the right atrium of the heart.
- The heart has four chambers and four valves to ensure blood flows in the correct direction. Blood travels from the right atrium to the right ventricle through the tricuspid valve, then through the pulmonary valve into the pulmonary artery. After gas exchange in the lungs, oxygenated blood returns through the pulmonary veins to the left atrium, then to the left ventricle through the mitral valve. Finally, oxygenated blood leaves the left ventricle through the aortic semi-lunar valve into the aortic arch, distributing blood to the body through the largest artery, the aorta, with branches supplying the head, arms, pelvis, and legs.
