Do Humans Breathe Oxygen or Carbon Dioxide?

Humans and other animals breathe in oxygen and breathe out carbon dioxide. Oxygen is essential for life. It is taken in through the lungs and is used by cells throughout the body to create energy. Carbon dioxide is a waste product of cellular respiration and is exhaled out of the body.

Oxygen is a colorless, odorless gas that makes up 21 percent of the air. It is essential for the functioning of the human body and is taken in through respiration. Oxygen is used by cells to create energy through a process known as cellular respiration.

Carbon dioxide is a colorless, odorless gas that makes up about 0.04 percent of the air. It is a waste product of cellular respiration and is exhaled out of the body. Carbon dioxide is also absorbed by plants, which use it as a source of energy during photosynthesis.

In conclusion, humans and other animals breathe in oxygen and breathe out carbon dioxide. Oxygen is essential for life and is used by cells to create energy, while carbon dioxide is a waste product of cellular respiration and is exhaled out of the body.
