Question

describe gaseous change in human body​

Answer 1

Answer:

In a human body, exchange of gases takes place in the human lungs, and more precisely in alveoli in the lungs. As we take in O2 from our nose, it passes through the wind pipe and trachea and reaches the lungs. The oxygen diffuses out from the alveoli to the blood and blood is oxygenated and then carried to heart by pulmonary artery. The carbon-di-oxide diffuses from blood into the alveoli which is then expelled by the lungs.

Answer 2

• The biological process through which gases are transported across cell membranes to enter or exit the blood is known as gas exchange.
• For aerobic cellular respiration, cells require oxygen all of the time, and the same mechanism produces carbon dioxide as a waste product all of the time.
• Throughout the body, oxygen leaves the blood and enters the cells, while carbon dioxide exits the cells and enters the blood.
• The blood and the air in the lungs also interchange gases, with oxygen entering the blood from breathed air and carbon dioxide exiting the blood and entering the air to be expelled from the lungs.
