Blood picks up multiple things from cells. They pick up waste products like carbon dioxide and water, and they also pick up oxygen from the lungs.

lungs
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.
Red blood cells pick up oxygen and deposit carbon dioxide at the lungs

Yes, red blood cells pick up oxygen in the lungs through a process called oxygenation. Oxygen binds to hemoglobin, a protein in red blood cells, and is then carried to tissues throughout the body for cellular respiration.
At the capillary level of our cardiovascular system tiny vessels pick up waste products from cells.
The job of a blood cell is to pick up oxygen from the lungs and carrying oxygen to the other cells in the body.
