How blood is pumped by the heart?
The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.
Do all arteries carry oxygen-rich blood?
Most arteries carry oxygenated blood, and most veins carry deoxygenated blood; the pulmonary arteries and veins are the exceptions to this rule.
Which artery contains oxygen rich blood?
The left ventricle (LV) pumps the oxygen-rich blood through the aortic valve (AoV) into the aorta (Ao), the main artery that takes oxygen-rich blood out to the rest of the body.
What veins carry oxygen-poor?
The inferior and superior vena cava bring oxygen-poor blood from the body into the right atrium. The pulmonary artery carries oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium.
Why must blood be pumped nonstop in our bodies?
Your heart is a pumping muscle that works nonstop to keep your body supplied with oxygen-rich blood. Signals from the heart’s electrical system set the speed and pattern of the pump’s rhythm.

Looking at the outside of the heart, you can see that the heart is made of muscle. The strong muscular walls contract (squeeze), pumping blood to the rest of the body. On the surface of the heart, there are coronary arteries, which supply oxygen-rich blood to the heart muscle itself.
What do you call the largest blood vessels in the body?
The largest artery in the body is the aorta, which is connected to the heart and extends down into the abdomen (Figure 7.4. 2). The aorta has high-pressure, oxygenated blood pumped directly into it from the left ventricle of the heart.
What type of blood is carried by blood vessels to lungs?
In general, arteries and arterioles transport oxygenated blood from the lungs to the body and its organs, and veins and venules transport deoxygenated blood from the body to the lungs.

- Compression stockings.
- Manage Blood Pressure.
- See a Vascular Surgeon.
What causes poor blood circulation in legs?
