yes
Veins carry blood to the heart. They usually carry oxygen-poor blood.
Veins are the blood vessels that usually carry oxygen-poor blood. The exception is the pulmonary vein, which carries oxygenated blood.
Usually veins carry blood low in oxygen back to the heart except for the pulmonary veins. They carry blood higher in oxygen.
The lungs, where they become oxygen-rich blood
Systemic veins, not to be confused with pulmonary veins, carry oxygen poor blood back to the heart.
Arteries carry oxygen-poor blood from the heart; veins carry oxygen-poor blood back to the heart.
The pulmonary veins do not carry oxygen-poor blood to the right ventricle. Instead, the pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart.
Arteries carry oxygen-poor blood from the heart; veins carry oxygen-poor blood back to the heart.
Pulmonary alveolus!
Aorta carry that. And the veins carry the oxygen poor blood back to the heart and lungs.
Arteries always carry blood away from the heart. Veinsalways carry blood back to the heart.Most arteries are high in oxygen except for the pulmonary arteries. Most veins are low in O2.And then there are the pulmonary veins. The only veins that carry blood high in oxygen.
Veins carry blood back to the heart, while arteries carry blood away from the heart. Veins have valves to prevent backflow, while arteries do not. Arteries have thicker walls and carry oxygen-rich blood, while veins have thinner walls and carry oxygen-poor blood.
