Respiratory, muscular, and cardiovascular/circulatory systems.

There are many organ systems that work together, but the main ones are the respiratory system, the muscular system, and the cardiovascular/circulatory system. The respiratory systems intakes the oxygen. The muscular system make this possible. An example would be the diaphragm, which helps the lungs to take in the oxygen. The cardiovascular system transports the oxygen to the cells through the blood.

The organ systems that must work together to bring oxygen to the body's cells are the circulatory system, respiratory system, and cardiovascular system.

What is an Organ system?

An organ system may be defined as a biological system comprising a cluster of organs that significantly work together in order to perform one or more specific functions.

The circulatory system deals with the flow of blood, oxygen, and nutrients to each and every cell of the organism. But this oxygen that we inhale is the functional mechanism of the respiratory system.

The heart, arteries, capillaries, etc. are the parts of the cardiovascular system. The heart, blood, and blood vessels significantly work together in order to deliver the amount of oxygen to the body's cells.

Therefore, the organ systems that must work together to bring oxygen to the body's cells are the circulatory system, respiratory system, and cardiovascular system.
