Question

What is meant by Breathing ?​

Answer 1

breathing:- BREATHING IS ALSO KNOW AS EXTERNAL RESPIRATION. IT INVOLVES TWO STEPS :- INHALING AND EXHALING...

DURING INHALATION WE TAKE IN AIR RICH IN OXYGEN AND DURING EXHALATION WE EXHALE OUT AIR RICH IN CARBON DIOXIDE WHICH IS THE END PRODUCT OF OUR INTERNAL RESPIRATION ..

Answer 2

• Breathing (or ventilation) is the act of moving air out and in the lungs to permit gas exchange with the internal environment, primarily to remove carbon dioxide and introduce oxygen.
• All aerobic animals require oxygen for cellular respiration, which creates carbon dioxide as a waste product from the interaction of oxygen with molecules received from food.
• Breathing, often known as "external respiration," is the process of bringing air into the lungs, where it is diffused into the alveoli, where gas exchange occurs.
• These gases are transported to and from the cells through the circulatory system, which is where "cellular respiration" takes place.
