Question

breathing and exchange of gases of all question​

Answer 1

Answer: The trachea branches into two bronchi, each leading into a lung. Each bronchus divides into smaller bronchi, and again into even smaller tubes called bronchioles. At the end of the bronchioles are air sacs called alveoli, and this is where gas exchange occurs. An important structure of respiration is the diaphragm.
