Carbon dioxide.
the answer is quite simple ...... carbon dioxide is the waste gas and it leaves the blood and then leaves the body when you exhale.
carbon dioxide
Because to carry out the process of diffusion of gas.
Oxygen is the gas that enters the blood during inspiration. It is taken into the lungs from the outside air and then diffuses into the blood vessels in the lungs.
It is carbon dioxide which is collected from different organs of the body by blood
The answer to this very question is simply gas. When blood leaves the heart deoxygenated it immediately goes to the lungs to receive oxygen which is a gas and this gas goes to the left side of the heart.
During expiration, the percentage of carbon dioxide is higher compared to other gases such as oxygen and nitrogen. This is because carbon dioxide is a waste product of cellular respiration and needs to be exhaled from the body.
they are connected to a densed network of blood vessels which keeps the oxygen moist
oxygen
•The normal airway is distended by alveolar attachments during expiration, allowing alveolar emptying and lung deflation. In COPD, these attachments are disrupted because of emphysema, thus contributing to airway closure during expiration, trapping gas in the alveoli and resulting in hyperinflation
Normal inspiration and expiration is directly related to contraction and relaxation of the diaphragm. This is involuntary act, normally.
The spongy layer in plant leaves helps with gas exchange, allowing for the exchange of carbon dioxide and oxygen during photosynthesis.
