State that blood is pumped away from the heart in arteries and returns to the heart in veins
Answered step-by-step
Blood is pumped away from the heart in arteries and returns to the heart in veins.
- Arteries: These blood vessels carry oxygen-rich blood away from the heart to various parts of the body. The main artery, the aorta, branches into smaller arteries that distribute oxygen and nutrients to tissues and organs.
- Veins: After delivering oxygen and nutrients, blood becomes deoxygenated and returns to the heart through veins. Major veins, such as the superior and inferior vena cavae, bring this oxygen-poor blood back to the right atrium of the heart, completing the circulatory loop.
This system ensures continuous circulation of blood, providing essential substances to cells while removing waste products.
