In the human body, carbon dioxide (CO2) is produced as a byproduct of cellular respiration, primarily in the mitochondria of cells. It diffuses into the bloodstream, where it is transported to the lungs primarily in three forms: dissolved in plasma, bound to hemoglobin, and as bicarbonate ions. In the lungs, CO2 is expelled from the blood into the alveoli, from where it is exhaled during respiration. This process is crucial for maintaining acid-base balance and ensuring efficient gas exchange.
The driving force behind gas exchange in the human body is the concentration gradient of gases such as oxygen and carbon dioxide between the alveoli in the lungs and the blood in the pulmonary capillaries. Oxygen moves from the alveoli into the blood, while carbon dioxide moves from the blood into the alveoli, driven by differences in their partial pressures.

Oxygen and carbon dioxide are the two main gases present in the human body. Oxygen is essential for cellular respiration and is carried by red blood cells, while carbon dioxide is a waste product produced by cells and is removed from the body through exhalation.
When we breathe in, air enters our lungs through the trachea (windpipe) and moves into smaller airways called bronchi, bronchioles, and finally, into tiny air sacs called alveoli. In the alveoli, oxygen from the air passes into capillaries to enter the bloodstream, while carbon dioxide moves from the blood into the alveoli to be exhaled when we breathe out. This gas exchange process allows oxygen to be delivered to cells throughout the body and removes carbon dioxide waste.
It transfers food to the stomach, connects to the lungs for the inhalation of oxygen and the exhalation of carbon dioxide.

The respiratory system moves oxygen in and carbon dioxide (CO2) out.

CO2 and carbon dioxide
The circulatory system, which includes the heart, blood vessels, and blood, moves glucose, oxygen, and carbon dioxide around the body. Blood carries glucose and oxygen to cells for energy production, and carbon dioxide is transported back to the lungs to be exhaled.

Oxygen diffuses into cells. Carbon dioxide diffuses out.
Yes, oxygen and carbon dioxide are exchanged in the human body through the process of respiration. When we inhale, we take in oxygen from the air which is used by our cells for energy production. Carbon dioxide, a waste product of this process, is then expelled from the body when we exhale.
