Final answer:
Red blood cells, or erythrocytes, are responsible for absorbing oxygen and depositing carbon dioxide in the lungs.
Step-by-step explanation:
The blood cells responsible for absorbing oxygen to be distributed to the body and depositing carbon dioxide into the lungs are red blood cells, also known as erythrocytes. Red blood cells contain a molecule called hemoglobin, which binds to oxygen in the lungs and carries it to the body tissues. As they pass through the capillaries in the tissues, oxygen molecules detach from hemoglobin and enter the cells.
In exchange, red blood cells pick up carbon dioxide produced by cells and transport it back to the lungs, where it is exhaled. This exchange of gases occurs in the respiratory system, specifically within the alveoli of the lungs and the body's capillaries.
It is worth noting that there are also other blood cells involved in the immune response and blood clotting, such as white blood cells (leukocytes) and platelets (thrombocytes).
