Human cells need oxygen for respiration. What system of the body is responsible for transporting an oxygen molecule to different locations throughout the body?

The skeletal system provides structure and support to the body but does not have a role in transporting oxygen. Its primary function is to protect vital organs, facilitate movement through attachment to muscles, and store minerals, rather than engaging in the transportation of gases like oxygen.

The lymphatic system is primarily involved in immune functions and the maintenance of fluid balance in the body. It transports lymph, which contains white blood cells, but it does not play a direct role in the transport of oxygen molecules. Oxygen transport is specifically the function of the circulatory system through blood.

While the respiratory system is responsible for the intake of oxygen into the body and the expulsion of carbon dioxide, it does not transport oxygen throughout the body. Instead, it facilitates the exchange of gases in the lungs, where oxygen is then taken up by the blood in the circulatory system for distribution.
