The cardiovascular system is a two-loop system because blood circulates through two loops: the pulmonary circulation loop and the systemic circulation loop. In the pulmonary circuit, blood is pumped from the heart to the lungs to pick up oxygen and release carbon dioxide. In the systemic circuit, oxygen-rich blood is carried from the heart to the rest of the body to deliver oxygen and nutrients. This two-loop system allows for efficient delivery of oxygen and nutrients to the body's tissues.

The job of a blood cell is to pick up oxygen from the lungs and carrying oxygen to the other cells in the body.
They are transported to an oxygen rich environment, the lungs. It is there that they pick up their oxygen.
The red blood cells pick up oxygen from the air that is inhaled into the lungs. When the red cells pick up the oxygen from the air, they expel carbon dioxide into the lungs to be exhaled.
Blood moves through the heart in a continuous loop, starting with the right atrium receiving deoxygenated blood from the body. The blood then flows into the right ventricle, which pumps it to the lungs to pick up oxygen. Oxygenated blood returns to the left atrium, then moves to the left ventricle, which pumps it out to the rest of the body. This cycle repeats with each heartbeat, ensuring that oxygen-rich blood reaches all parts of the body.
In the lungs, in the alveolar capillaries
Blood picks up oxygen in the lungs when it diffuses across the thin walls of the alveoli into the bloodstream. This oxygen is then carried by red blood cells to tissues throughout the body.
