Detailed explanation-1: -Answer. Blood with fresh oxygen is carried from your lungs to the left side of your heart, which pumps blood around your body through the arteries. Blood without oxygen returns through the veins, to the right side of your heart.

Detailed explanation-2: -Without blood, the body’s organs couldn’t get the oxygen and nutrients they need to survive, we couldn’t keep warm or cool off, fight infections, or get rid of our own waste products. Without enough blood, we’d weaken and die. Here are the basics about the life-sustaining fluid called blood.

Detailed explanation-3: -From there, the blood flows through the right and left pulmonary arteries into the lungs. In the lungs, oxygen is put into the blood and carbon dioxide is taken out of the blood during the process of breathing. After the blood gets oxygen in the lungs, it is called oxygen-rich blood.
