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 lungs, which carry out this exchange of gases as we breathe. Red blood cells collect the oxygen from the lungs and carry it to the parts of the body where it is needed, according to the American Lung Association. During the process, the red blood cells collect the carbon dioxide and transport it back to the lungs, where it leaves the body when we exhale.

The human body needs oxygen to sustain itself. A decrease in oxygen is known as hypoxia and a complete lack of oxygen is known as anoxia and, according to MedLine Plus. Prehistoric Van Goghs: Artists Used Pointillism 38,000 Years Ago Nineteenth-century artists, such as Georges Seurat and Vincent van Gogh, weren't the first to use pointillism, according to a discovery of 38,000-year-old decorated limestone tablets in France.

The gas exchange process is performed by the lungs and respiratory system. Air, a mix of oxygen and other gases, is inhaled.

In the throat, the trachea, or windpipe, filters the air. The trachea branches into two bronchi, tubes that lead to the lungs. Once in the lungs, oxygen is moved into the bloodstream. Red blood cells collect carbon dioxide from the body’s cells and transports it back to the lungs. An exchange of oxygen and carbon dioxide takes place in the alveoli, small structures within the lungs.

The diaphragm is a dome-shaped muscle below the lungs that controls breathing. Related:
