Low oxygen/de-oxygenated blood is carried by:
To transport blood.
Arteries and the pulmonary vein transport oxygen-rich blood through the body.
HR changes in response to workload, the harder you work the more oxygen is needed. Blood is the transport vessel for that oxygen. Faster HR = more blood and therefore more oxygen.
red blood cells transport oxygen :)
The ventral blood vessel is responsible for pumping blood throughout the body of certain invertebrate animals, such as earthworms. It is a part of the circulatory system and helps transport oxygen and nutrients to various tissues and organs.

Blood vessels that carry blood back to the heart are the veins. Blood vessels that carry blood away from the heart are called arteries. veins
The umbilical vein carries oxygen-rich blood from the placenta to the fetus, making it the fetal blood vessel with the highest oxygen concentration.
pulmonary vein
This artery is called the dorsal aorta and it is a main artery leading from the heart. It divides and branches out to smaller arteries that ensure that all of the body is supplied with oxygen.
