How does the circulatory system work with the respiratory system and the nervous system?

The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Your nervous system interacts with every other system in your body, all of your tissues and organs require instruction and direction from the nervous system.

The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.
