atmosphere
CO2 - Carbon dioxide.
exhaled
This gas is carbon dioxide, which is produced by cells during metabolism. It is transported back to the heart through the bloodstream, where it is then pumped to the lungs. In the lungs, carbon dioxide is exchanged for oxygen during respiration and is released into the atmosphere when we exhale. This process is essential for maintaining the body’s acid-base balance and overall respiratory function.
Oxygen is primarily carried to the cells by hemoglobin in red blood cells, which binds oxygen in the lungs and transports it through the bloodstream. Once it reaches the cells, oxygen is released and utilized for cellular respiration to produce energy. Afterward, carbon dioxide, a waste product of this process, is carried away from the cells back to the lungs for exhalation.
The carbon dioxide diffuses into the plasma portion of the blood and is carried to the heart. From there it is carried to the lungs where it is released when you exhale.
It is brought back to the heart to be pumped through the lungs to be exhaled.
As the blood passes though the pulmonary circulation, oxygen within the lungs binds with the hemoglobin and is carried from the lungs back to the heart and then from there on to the active tissues of the body.
Waste gases, primarily carbon dioxide, are released from the lungs during the process of respiration. When we inhale, oxygen enters the lungs and is transported to the bloodstream, where it is used by cells for energy production. As a byproduct of this process, carbon dioxide is produced and carried back to the lungs via the bloodstream. During exhalation, the diaphragm and other respiratory muscles contract, pushing the carbon dioxide-rich air out of the lungs, thereby removing waste gases from the body.
Carbon dioxide is the molecule produced in the citric acid cycle as a byproduct of glucose oxidation. It is subsequently released into the bloodstream and carried to the lungs, where it is removed from the body through exhalation.
from nose through airway in throat into lungs
Gas is carried mostly by the plasma in the blood. The plasma contains dissolved gases such as oxygen and carbon dioxide, which are transported to different parts of the body. Oxygen is transported from the lungs to the tissues, while carbon dioxide is carried from the tissues back to the lungs for elimination.
