- The respiratory system's main job is to move fresh air into your body while removing waste gases. Once in the lungs, oxygen is moved into the bloodstream and carried through your body. At each cell in your body, oxygen is exchanged for a waste gas called carbon dioxide.

Oct 22, 2024 · Human respiratory system - Circulation, Metabolism, Oxygen: The interplay of respiration, circulation, and metabolism is the key to the functioning of the respiratory system as a whole. Cells set the demand for oxygen uptake and carbon dioxide discharge, that is, for gas exchange in the lungs.
Apr 14, 2017 · The transportation route relies on red blood cells which contain oxygen-binding molecules called hemoglobin. Every second, your body churns about 2.5 million blood cells, so the oxygen sent to your lungs has a vast amount of transportation.

Oxygen-deficient, carbon dioxide-rich blood returns to the right side of the heart through two large veins, the superior vena cava and the inferior vena cava. Then the blood is pumped through the pulmonary artery to the lungs, where it picks up oxygen and releases carbon dioxide.
In your body, oxygen forms a vital role in the production of energy in most cells. But if gases can only efficiently diffuse across tiny distances, how does oxygen reach the cells deep inside your body? Enda Butler tracks the surprisingly complex journey of oxygen through your body.
Aug 6, 2018 · Body cells use oxygen to convert stored energy. This process, which is called cellular respiration, allows the cells to harness energy to perform vital functions such as the movement of materials into and out of cells. Without oxygen in the body, cells can function for only a limited period.
How does oxygen travel into blood? Air is breathed into the lungs through the windpipe called the trachea. The trachea divides into two tubes called the bronchi.
Oct 18, 2024 · The transport of oxygen (O2) and carbon dioxide (CO2) in the blood is a vital aspect of respiratory physiology, ensuring that tissues receive enough oxygen for metabolic processes and that waste products, such as carbon dioxide, are efficiently removed from the body.
