The VEINS are blood vessels that usually carry oxygen-poor blood, while the ARTERIES carry oxygen-rich blood.
- The arteries are blood vessels that transport oxygen-rich blood from the heart to all the cells of the body.
- This element (oxygen) is then used by body cells to carry out cellular respiration and thus obtain energy (ATP).
- Conversely, veins are blood vessels that return deoxygenated blood collected in the capillaries from all body cells to the heart.
In conclusion, the VEINS are blood vessels that usually carry oxygen-poor blood, while the ARTERIES carry oxygen-rich blood.
