Answer:
Respiratory system
The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are the lungs, which carry out this exchange of gases as we breathe.
The lungs work with the circulatory system to pump oxygen-rich blood to all cells in the body . The blood then collects carbon dioxide and other waste products and transports them back to the lungs, where they are pumped out of the body when we exhale.
The human body needs oxygen to sustain itself.
Hope it's useful to you !!
