At the capillary level of our cardiovascular system tiny vessels pick up waste products from cells.
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.

Capillaries
In exchange, the blood picks up waste from the cells, including carbon dioxide, heat and excess water. The heart pumps blood throughout the body through a closed system of tubes. These tubes that carry the blood are called blood vessels. There are three types of blood vessels: arteries, veins, and capillaries. LESSON 1.1 -
In the small intestine.
In muscles and other body tissues, there are capillary beds which connect arterial supply and venous return. Arteries end as capillaries in the body tissue, where blood dumps oxygen and nutrients for use by muscles. At this point they are considered arterial. They may also pick up waste products to carry away. By the end of the capillary beds, they are depleted and considered venous. They flow continuously into the veins which flow back to the heart. The heart sends this blood to the lungs to pick up oxygen and the cycle continues.
The lungs
The pulmonary system is connected to the pulmonary system in two ways. First the circulatory system does the same for the pulmonary system as it does for every other part of the body -- it supplies food and oxygen and removes waste products and CO2. But, in addition the heart pumps blood through the lungs to remove CO2 and pick up oxygen.
The blood picks up oxygen in the lungs and gives it to all the organs in the body that needs it.
It's the side that receives blood from your body and sends blood to the lungs to pick up oxygen.
The entire purpose behind the human heart is to pump deoxygenated blood to the lungs to pick up oxygen and oxygenated blood to peripheral tissues to supply them with oxygen. With no human heart there would be no way to deliver oxygen to cells and get rid of carbon dioxide from them.
The job of a blood cell is to pick up oxygen from the lungs and carrying oxygen to the other cells in the body.
